Everybody seems to recommend Nielsen&Chuang as an introductory book for quantum computation/information/communication. quora.com/… makes me feel that a more up-to-date book might be nicer. Is there one that is almost as good?

Ack!

Ack ack ack!

Nielson and Chuang is ok from the perspective of someone only interested in the mathy algorithm side of quantum computing.

I did my MSc in physics (quantum physics, mostly nanoelectronics with bits and pieces of quantum computation) and am currently working towards a PhD in information theory/combinatorics/computer science/whatever, and quantum computing/information/communication/whatever feels too much like a nice combination of these to know almost nothing about. Mostly I'd study just for fun, but if possible, I'd also like to be ready if a professional opportunity to work with related things arises.

It says nothing of any use about how quantum computing actually works.

Guys, what's with all the Jim jokes?

@alarge This is completely false :-)

Physicists with hardware skills are in demand and get paid a lot.

This is especially true if you don't mind working in the military industrial complex, but even outside of it physicists who can build things are highly sought after.

@GeorgeSmyridis please talk to me about the job issue. Most of the people you're talking to here are theorists and might not have an accurate picture of what it's like to work in applied industries as a physicist.

@JiK If you're interested in how quantum computing works I'd recommend learning basic quantum mechanics first.

4:02 AM

@DanielSank I can attest to the high salary offers. But I never got offered the job despite having spent my grad school days and post docs on a mixture of design-n-builds and assorted computer programing tasks around going from signals on a board to data on a disk to physics in a paper.

4:32 AM

@dmckee This is hard for me to believe. What kinds of jobs did you look for? What do you mean by saying you can attest to high salary offers but never got offered "the job".

@EmilioPisanty (and everyone) just so you know, the recommendation from SE is that whenever something is spam (i.e. promotional and irrelevant), just flag it as spam, rather than editing out the link and/or using another flag

10:45 AM

@DavidZ I think there is a question lurking there, though. Mediocre at best but still on-topic.

Or at least with a chance of being on-topic.

11:07 AM

Yeah, I suppose so. But an account that posts blatant spam is unlikely (in my experience, and that of other network mods) to ever contribute anything legitimate. So it helps out the automatic spam filter to just flag it. You can always leave a comment if you do think the user is salvageable, but it's best to have them make a new post.

11:27 AM

@ChrisWhite Why the rollback? Do you dislike precision? Are you even a real physicist?

Q: How is quantization related to commutation?

How are commutation (of observables) and quantization related? Reading about the Stone-Von Neumann Theorem, it seems that commutativity is the classical limit of quantum mechanics, and hence non-quantization, but I don't understand the intuition behind the fact that commutativity of operators sho...

@dmckee Without pedantry there is no accuracy. Without accuracy science is a joke. You are a joke, Mr. Despot Mod.

@dmckee You take no responsibility for the truth. Understood.

The brave user 12... has shown us the ugly reality: the SE moderators are enemies of the truth!

1:57 PM

@0celo7 Or enemies of incoherent babble

Why the fuck would you sign a petition and only include your street name and number...how the fuck are we supposed to know the town, state or zip code?

@0celo7 Look at the towns & states around the blanked one & impute

@KyleKanos Incoherent because you deny it outright as the truth. Just because it doesn't appear in your "peer reviewed" journals does not affect veracity.

Who are these "peers" anyway? Members of the scientific oligarchy, no doubt.

@KyleKanos That's funny.

People just write down everyone they know.

Hmm. Considering scientists are the ones who do science, not sure they'd qualify as an oligarchy since it's really "everyone involved" & not a "select few"

@KyleKanos Typical academic lackey.

@KyleKanos What's also maddening are people who sign where it says "name". I can't read people's signatures accurately.

Also people who only write the town and state. We need a street address to count the signature. Also people who don't write the zip code...why?

2:05 PM

@0celo7 You are beginning to make me question Kay's observation

Men in Black - People

@0celo7 Google Maps is the best (double true)

@KyleKanos It's unnecessary work.

True. But you should really be complaining to/about the people getting the signatures and not the people signing the form

I'm just delivering a PSA here.

Well I don't sign petitions because they're usually meaningless

@KyleKanos I don't get it.

Why am I making you do that?

2:10 PM

@0celo7 You're either making a poor joke or trying to rehearse for your high school speech in a fake tone of machismo.

@Gaurav High school speech? I'm not even in high school...

@0celo7 Because persons are being dumb

@0celo7 Then don't act like one.

@Gaurav What?

@KyleKanos I still don't get it.

Which exact part are you questioning?

Okay....Kay's observation is A person is smart, but people are dumb... You are giving examples of persons being dumb

(dumb because they cannot follow directions)

2:16 PM

@KyleKanos I thought he meant people think they are smart, but are actually dumb.

He's talking about the difference between an individual and a collective. The former can be smart while the latter usually is not (e.g. "mob mentality")

I see.

Holy crap....I just realized that you weren't even born when that movie came out

Today is Leibniz's Birthday.

user image

Dat hair

Better than @ChrisWhite's.

user54412

lol

user image

@skillpatrol Were Leibnitz-era mathematicians aware of $\mathrm{i}$?

Also $(n)_i$ is senseless. Why the parenthesis?

3:01 PM

$i$ as in imaginary number? If so, yes: en.wikipedia.org/wiki/Imaginary_number#History

@0celo7 it's a pronunciation thing

Is that integral even sensible?

@KyleKanos I think you mean $\mathrm{i}$.

@KyleKanos If one of those symbols is a 1-form, perhaps.

user54412

Or it's a Lebesgue integral...

@0celo7 No way, $i$.

3:06 PM

@ChrisWhite You still have to specify the measure, no?

@KyleKanos $i$ is just some confusingly named variable.

user54412

It always seemed to be omitted in all my analysis courses, probably because we only ever used the usual measure on $\mathbb{R}$

@0celo7 $i^2=-1$, duh

@ChrisWhite That's just lazy notation.

user54412

@0celo7 Welcome to Physics!

@ChrisWhite Says the fake physicist...

@KyleKanos So $i^2=\mathrm{i}^2$, which implies $i=\pm\mathrm{i}$.

3:10 PM

what is real?

@skillpatrol Defining clocks and ~~time~~ duration rigorously.

@skillpatrol Spacetime, according to Brian Greene

tough questions :(

user54412

@0celo7 Hard to do, what with that leap second and all.

@ChrisWhite Humans are so selfish, we literally changed time.

3:12 PM

@0celo7 Pfft, we defined time

@KyleKanos Not according to Mr. user 12...

@0celo7 I'm pretty sure he's defined time in an arbitrarily complex and useless way

@skillpatrol

user image

Mirrors and eyes are on the list of "not real" things.

@KyleKanos Precision is not arbitrary. Freaking engineers taking over physics.

@0celo7 I'd argue he's not being precise

@KyleKanos Defend your claim.

Extraordinary claims require extraordinary proof.

3:18 PM

It's basically semantics. He's taking the same definitions as everyone else and changing the verbiage.

He then is completely careless with his math

Like defining $\hat{E}=i\hbar\partial_r$ and then applying it to some $\mathcal A$ and then just dropping the $i\hbar$ terms because the result should be classical & not QM

@KyleKanos How so?

@KyleKanos Makes sense to me.

Well that's not really mathematically rigorous, is it?

Just like going from GR to SR, to go from QM to CM, remove the $\mathrm{i}\hbar$.

@KyleKanos Mathematical rigor is dictated by physics.

@KyleKanos In all seriousness, he did that?

I queried him about it and he said something to the effect of "Oh, there's a phase term, $\phi\sim e^{i\hbar r}$ that cancels the $i\hbar$"

@0celo7 Yes: physics.stackexchange.com/questions/190959/…

oO

3:24 PM

Shit...well the phase I wrote was wrong but is in the link above

Why are there $\hbar$s in a classical question

Because everything is QM?

Fuck his notation, seriously.

What is this stuff?

Well the downvote alt-text does say This answer is not useful, so if you think his notation is useless, vote that way

I want to know how he got the right answer!!

What?? How does any of that work?

3:28 PM

He fudged his math, duh?

He might be on to something...this must be investigated!

user image

@KyleKanos You don't think this has merit?

@0celo7 No. He's reinventing the wheel and making it square instead of round

And then pretending it's round and trying to convince everyone that it is round by hiding it behind obscurity

@KyleKanos See my comment.

3:36 PM

Are you trying to humor him with "fantasic work" so that he is more agreeable than defensive?

Or are you serious about that?

@KyleKanos Why would I do that?

@KyleKanos If he can prove SR follows from QM, you bet it's fantastic work.

Because he gets really defensive really quickly and basically calls you a know-nothing

Of course, we both know that's bullshit.

@KyleKanos Cool, I could use the lols.

Also: he has no idea that Chat allows MathJax, so please don't encourage him

@KyleKanos Huh?

3:39 PM

You'll eventually get the "Take this to Chat" message

If you do get there & opt for it, don't inform him about how ChatJax works

Because otherwise he's going to spend his time here and annoy us

We can block him...

Hmm, true

I'll butter him up, don't worry.

I will attempt to troll the troll.

Never attempt to "troll a troll"

@skillpatrol How do you know I'm not trolling you right now? Maybe I am that user...

Only KK knows who I am.

The rest of you have no clue...

3:46 PM

He'll drag you down to his level and beat you with experience ;-)

I know half of what you look like

@KyleKanos You have seen the fabled iPad.

@skillpatrol I can tango with the devil just fine.

I have played enough fps games on Xbox Live.

This is true, I've seen the back of the iPad

I should have brought a textbook or something. Extra verification.

Next hearing. Any preferences?

All I'm saying is let sleeping dogs sleep

11 mins ago, by Kyle Kanos

Because otherwise he's going to spend his time here and annoy us

3:51 PM

@skillpatrol Aw fuck, I should have gotten Sleeping Dogs during the Steam sale!!!!

I totally forgot LA Noire as well.

So many games I want to play!

BTW, GTA 5 was fantastic.

Some questionable design choices and the story wasn't as good as 4's, but still a very, very good game.

I think I now know what people mean when they say a game is a "console port".

What do they mean?

user54412

LA Noire was clearly ported, in that it couldn't even run with default settings on a PC. The devs didn't know how multi-core processors worked. Once you restrict it to a single core, it runs fine.

user54412

@skillpatrol The interface is the most noticeable thing. Something that works for ~10 buttons will not work for a keyboard+mouse, ever. But lazy porters don't redesign interfaces.

@skillpatrol The menu is totally console, for one. Also, the world, while big, is missing interiors to accommodate shitty console RAM.

@ChrisWhite wat

I see, thanks.

3:58 PM

Does GTA 4 work fine?

user54412

Never tried.

That's my first buy next time it goes on sale.

GTA 5 gfx are confusing. I'm only using 70% of my GPU, but when I up any settings my fps crashes to 20.

user54412

Just keep in mind if things don't work there is almost always a fix for a PC.

@ChrisWhite I'm running Win on a Mac, I've already had issues with that.

user54412

@0celo7 Laptop GPU? Maybe it's overheating? Could always be more subtle, like memory access bandwidth not being enough because they got lazy and coded inefficiently or something.

user54412

4:02 PM

Crysis wasn't GPU intensive because it had more features than other games at the time, it simply had worse programmers.

@ChrisWhite It's running 30 degrees below the built-in cutoff.

user54412

Probably something more subtle then. Though it might be fun to check if your CPU is being overheated by the GPU.

@ChrisWhite So a CPU issue?

I know I can run older games on absolutely max settings fine and the GPU goes up to 95% output.

user54412

not saying it is, just saying it would be an interesting data point

I wish more games had an fps lock.

I want to do ultra, but the variable fps is killer.

Even if it stays above 30, it's terrible.

@ChrisWhite I think the lighting and shadows are the issue, not the textures. The fps drops at night in GTA when I put it on "high" (which increases shadow detail and reflections).

4:14 PM

why is $\epsilon_{abcd}\epsilon^{fbcd}= 12 \delta^f_a$ when I use the formula for the contraction of levi civita symbols, I have the number of contracted indices $p=3$ and the dimension of the symbols is $n=4 \implies n-p=1$ Hence the coefficient $p!(n-p)!=3! 1 ! =6$. I am probably missing a factor of $2$.

@gonenc Work it out explicitly!

when i do that i get the correct answer but my question is why I fail to use the formula.

What is the formula?

user image

@gonenc Do you have another source for that?

It's good to verify.

4:19 PM

this is sean carroll

i think it is also in penroses road to relativity

I figured, but he's not immune to typos.

@0celo7 en.wikipedia.org/wiki/Levi-Civita_symbol equation #8

i can swear that ive seen it in the penrose's book but cannot find it :)

Ok, that's strange.

I get your answer.

And you swear working it out explicitly gives you 12?

if im not lost in calculation yes

i begin to think it could also be 6 :D

It's 6.

user54412

4:28 PM

Consider $a = f = 0$. Then the only contributions to the sum will be when $b,c,d = 1,2,3$ in some order. There are 6 permutations, so...

Wiki confirms, look at the very last set of equations.

yup

:D

@ChrisWhite Well when you put it like that

@KyleKanos No response from user12..., and I know he's been online.

user54412

4:43 PM

@0celo7 You can often set this directly on your GPU. There are various vendor-provided interfaces for this.

@ChrisWhite Remember, custom Mac drivers.

user54412

oh, hmm, never tried it on a mac

I'm using MSi Afterburner to monitor system stats and it has a blank where my driver version should be.

Also when I go to the ATI/AMD website to update the drivers, I get an error.

No clue how I would lock fps.

I'd totally do 30fps if that meant a stable game on ultra settings.

user54412

yeah, I think afterburner should be able to lock fps, if only it knew what your graphics card was

I knows the card, just not the driver version.

It will let me overclock it. I probably shouldn't do that.

user54412

4:56 PM

so device manager doesn't list a driver for the card?

user54412

you can manually select the appropriate driver from the website then

@ChrisWhite Not at home, will look when that is the case.

@ChrisWhite I don't think that's possible. OSX Boot Camp installs drivers to interface with Mac hardware.

user54412

The amd download site says "For [...] Apple Boot Camp systems [...] please select your driver using the selection menus below."

oO

Computer wizard

I think I have something called "AMD Catalyst" somewhere

I've seen that before while exploring

@0celo7 The present mods kept the community together through the greatest of crises that affected PSE. If it were not for them, the site might have well failed. I think they've displayed remarkable responsibility and maturity in handling affairs. For this reason, I think your reference to one of them as being "a joke" is horribly uninformed and quite ridiculous.

5:12 PM

Well I'm of the state of mind that Ocelot was himself joking about that

@Gaurav How could that be taken seriously? I know I'm all about Poe's law, but I'm on good terms with the mods...

What "great crisis" is that?

And, assuming that you're referring to Ron et al's leaving, I'm not sure that I'd categorize that as a crisis.

I have tied @ACuriousMind in Reopen queue on Meta!

And I'm 4 reviews away from 6k Close Reviews o.O

@KyleKanos I don't know how anything could be a "crisis" here.

@KyleKanos I have 5% as many.

@0celo7 I'd say shutting down the site would constitute a crisis.

@KyleKanos Besides that.

5:27 PM

Besides that...hmm, the community voting to allow HW questions. That would be a crisis

Most of the good/prolific answerers would stop showing up

@KyleKanos MSE gets along fine with great answerers

They've accepted the fact that the only way to help people understand math is to help them do HW

We don't think that's the case with Physics

(Also, it took me a few moments to realize you meant Math & not Mother Meta)

@KyleKanos I don't understand why there can't be a balance between homework and concept.

Maybe give people an allotment of homework questions so they don't ask only homework questions.

The line is often blurry (especially when people show their effort into the post)

But I think the "safe side" is to not allow it than to try cleaning up the blurry line

@KyleKanos I think "I have no clue how to do X" has a conceptual component, but gets swept under the rug of homework.

5:38 PM

@0celo7 There's usually a concept there, yes. Are they asking that? No

A commenter should immediately ask "Well what don't you get about it?"

This will (help) draw out the concept

Saying, "I don't know how to do this" isn't helpful because it's obvious & uninformative, really. If they knew how to do it, they wouldn't ask the question.

So what really they mean "How do you solve this?"

Then by asking "What don't you understand?" or "What have you tried?" someone is trying to see what concept it is that is stopping them from doing it or understanding it

Based on my teaching and SE experience, it feels a lot easier to give people reasonable hints for math homework than for physics homework. But that might be just because my students have been better in mathematics than in physics, and because I've never had the possibility to think about an unanswered Physics.SE question that I understand.

@JiK Suggestion: answer an answered question if your answer would give a slightly different analogy or perspective

6:04 PM

@KyleKanos I might try ... if I see a question I think I can answer before forgetting your suggestion.

I still have hundreds of pages of signatures.

HUNDREDS

Then there's questions like physics.stackexchange.com/questions/147455/… for which I immediately know the answer, but I have no idea whether it'd take me 2, 30, or 500 minutes to write an answer that's both understandable by the OP and technically correct.

@JiK Is he asking about swimming through air?

I don't know what swimming through air is.

What exactly is he asking then?

Seems to me he wants to move his body in such a way that he overcomes gravity.

Apparently he needs to be buff to do this.

6:24 PM

Yes, the idea is that having parts of the body to rotate seems to prevent them from falling* or make them easier to lift. (*Here I'd like to take the opportunity to blame English for using the same word for going down or rotating about an axis below your centre of mass.)

So nice to see the experimental discussion here

@Danu Actually...thinking about that some more, this is totally a textbook case of too-broad.

@KyleKanos I'm not sure.

It's literally asking for a list of ways to replicate 40 ft of water pressure

If asking for a list based on a vague description isn't too broad, I'm not sure what would be too broad

"What would be too broad?" probably would be too broad.

6:34 PM

@KyleKanos I think that's a relatively narrow scope :P

@Danu Seeing how there are 9 answers (some of whom are saying, "Well what do you have?") and at least a few of them are distinct suggestions (I didn't read all of them), I think it's safe to say it's pretty broad

@KyleKanos Sure, pretty broad. I don't think it's too broad.

IMO, if it's pretty broad, has multiple distinct answers, and was protected after 5 hours, it probably is off-topic

(I'm just making that categorization up on the spot, but I do think the question is too broad to be usefully answered here)

@KyleKanos Heh, okay. You're entitled to your opinion ;)

I mean the guy gives zero information outside I need to replicate 17 psi

6:44 PM

The protection is only because it's a hot network question

What the hell is going on for all these damn chat flags!?

@KyleKanos Seriously!

I'm watching the discussion

It's pretty dumb.

@Danu Why don't you give them both 5 minute chat bans?

Reason: for abusing flags in chat

@KyleKanos There are enough people dealing with it.

@Danu In the past I've had some periods of few weeks when I've done something for hour a day, but right now the last time I touched a chess piece was maybe three months ago.

@JiK That barely counts as an enthusiast! ;)

@KyleKanos What?

@0celo7 Shush, 10k stuff.

Chat flags?

7:02 PM

@Danu Oh, that profile text is probably written during such a period.

Q: How should I handle chat flags?

Chat flags cause quite a bit of drama. This FAQ might be useful to help avoid drama by educating those who handle chat flags. As a 10k chat user/chat moderator, I see a small blue circle in chat. What does it mean? How should I handle it? As a diamond moderator, how does this change?

@ACuriousMind Anything interesting in category land?

@0celo7 It's too hot, my brain is melting.

And I heard an absolutely abysmal talk about black hole firewalls today in my seminar.

Even reading the Wikipedia article is more enlightening.

8:14 PM

@ACuriousMind How hot is it? Please us human (F) units.

@ACuriousMind Handwaving galore?

I have roughly 5,000 more signatures to log.

This guy just signed Steve and crossed out the other fields.

@0celo7 About 100 F, I think

@ACuriousMind Germany does not get that hot.

@0celo7 There probably was some handwaving involved, buit I couldn't tell because of the broken English and the indecipherable and structureless stuff on the blackboard.

@ACuriousMind Like my calc class.

That was the greatest damn class I've ever taken.

He taught us how to memorize the quotient rule by relating it to taking off a woman's clothes during sex.

@0celo7 Oh, at the moment it does, we're at 34° to 38° C, check the conversion for yourself, if you like :P

8:20 PM

Google says 84 degrees.

@0celo7 wat

@0celo7 lol

29C in Heidelberg.

Now that the sun is down.

The day was hotter

33 high, so 92.

What is the humidity?

Not very high, fortunately

8:22 PM

DC is a swamp, we get 100F and 90% humidity. My sister who lives in LA said we're too hot out here for her.

42%

You pussy

@ACuriousMind And how to memorize the product rule by gender equality of domestic abuse.

Crazy shit.

It's nice today, about what you got.

@0celo7 As you said, we don't get that hot, usually. I think everything above 80 F is too hot :P

Your "brain melting" is our "nice".

@0celo7 Well, apparently you memorized at least the memory crutches perfectly :D

@ACuriousMind He was a Ph.D. student in computational whatever. He probably had a lot of time on his hands waiting for computations to come up with stuff.

@ACuriousMind Do people still die when it gets hot in Germany? I remember that being a big thing there back in the day.

@0celo7 It's very common for elderly and sick people's mortality rates to go up when there's such a heat wave, yes.

Btw, I just looked up that 104.4 F is the hottest temperature that was ever measured in the last hundred years or so here.

8:34 PM

What did you remove??

I must know

Hahahahaha

You will never know

@ACuriousMind By "back in the day", I meant 4 years ago

Maybe Germans decided ACs are good things

We had ceiling fans

@0celo7 Almost no home has an AC here, that's only something in public buildings.

@ACuriousMind Du bist ein boser Mensch

And, 99% of the time we really would have no use for ACs
