@Mithrandir24601 Seems like a good call. Especially during closed beta, it's kinda hard to imagine chat getting spammed too hard even if both feeds were enabled.

@Mithrandir24601 i'd be in favor of a meta feed, like in the hbar.

I wonder if we can set up the top left corner notifications on quantum-computing questions from a. the main site b. quantum-computing tag(s) on physics/cs/tcs like there are in the hbar

please no ticker :(

Someone with the right privileges can set up a feed though. If enough people want a ticker, then that becomes the rule, but I have to admit, I'm not a huge fan of it either

Q: Are there any experimental groups currently measuring quantum contextuality?

I work as a theorist with my current research interests in "quantum contextuality". For those perusing the question, this is essentially a generalization of non-locality where we can show a quantum system does not admit a hidden-variable model. So in some sense, it's impossible to look at the pro...

This question doesn't seem to be about quantum computing. Right?

Q: How do we deal with big-list type questions on this site?

As we know, big-list type questions are not very suitable for the Stack Exchange Q&A format. The answers to such questions to some degree depend subjective opinions and have no definitive answers. However, some sites like Physics SE have figured out policies to deal with such questions. Of course...

@Mithrandir24601 Does this seem suitable for the site-faq?

Q: If quantum gates are reversible how can they possibly perform irreversible classical AND and OR operations?

Quantum gates are said to be unitary and reversible. However, classical gates can be irreversible, like the logical AND and logical OR gates. Then, how is it possible to model irreversible classical AND and OR gates using quantum gates?

It doesn't seem a very intro-level question, but I guess it will be a common question asked by the beginners

I'm surprised that somebody downvoted it XD

@Blue hmm... I'm not sure... In my mind, it's a borderline case - yes as it's a type of "here's a gate that's conceptually important" but no because it's not (quite) something that's necessary to know to program a QC, which in my mind is what site-faq is for

I mean, I like that tag, but I don't think it's a good idea to overuse it. I guess it depends on how 'frequently asked' it is...

@Blue I'm not so sure about what the reversibility-irreversibility tag would be used for though?

With regards to quantumcomputing.stackexchange.com/q/120/55: The OP included in the question that "contextuality can often be formulated as a resource for quantum computation-- which is the reason why we're interested in it". It may be true that the answer to the question would not directly involve QC, but given that there is a clear link between quantum contextuality and QC it seems to be a slippery slope to close it.

Especially because it seems that it would be enough to add a few more background sentences including the words "quantum computing" to make it on-topic enough to most people, without really changing the answer

(this kind of questions is why I think it is not a great idea to try and have "quantum computing" excluding the other branches of quantum information science, which are all so intertwined with one another)

@Mithrandir24601 Agreed. I have removed the site-faq tag.

Anonymous

Also removed the other two tags "unitarity" and "reversibility-irreversiblity". But I think it would be nice to have a tag related to discussions of reversibility of quantum computations. Not exactly sure how to frame it.

@glS Thanks for pointing the mistake in my answer to the error correcting codes question.

@Blue np!

It's been just about a month or two since I started learning about QC. So it is very much possible that'll I'll often have no idea what I'm speaking about. Constructive criticism is always appreciated. :)

@glS I tentatively agree with this to some extent, so long as we don't go too far in the opposite direction

Hello everyone, My name is Andrew and I'm the physicist at Strangeworks. I'm looking forward to participating and generating more interest in quantum computing.

heather

hello @Andrew and welcome! do you want to provide a brief summary of what Strangeworks does?

Mithrandir24601

@AndrewO hi! Thanks for getting this off the ground! :)

heather

@Mithrandir24601 hello =)

Daniel Burkhart

@AndrewO Hello, welcome! Any interesting news from Strangeworks?

Mithrandir24601

@heather hi! long time, no chat

(Now I'm remembering why I started to use rytsas and ni hao - saying 'hi!' All the time feels a tad boring)

heather

rytsas then =)

Mithrandir24601

And bother autocorrect :P

@AndrewO Hi! I noticed that you are the only physicist at Strangeworks (?) Could you tell us a bit more about the company. The website you guys have is quite cryptic. :P

Anonymous

Are there plans to bring in more experts into the company?

vzn

@AndrewO hey welcome! was wondering/ hoping someone from strangeworks would show up. we cited some articles back in the transcript & are all very curious, there is very little info available so far... plz encourage your colleagues to join also :) fyi plz let me know if you or anyone from strangeworks may be interested in a scheduled meet/ greet/ intro chat session like this physics.meta.stackexchange.com/questions/7783/…

@AndrewO One of things that we were worried about is that this site was pulled out of Area 51 midway, during the commitment phase. So there might not be enough users to ask and answer questions in the long run. How's Strangeworks planning to overcome that?

heather

@Mithrandir24601 you know how I asked you once upon a time about non-unitary gates in quantum computing?

I'm posting a general question about it, thought it might be nice to add to the site. just a heads up =)

Anonymous

@heather That would be a interesting question. Here's something relevant I guess: arxiv.org/abs/quant-ph/0304061

Andrew O

Sorry for the delay, juggling a few things at the moment.

We'll be updating the website with more about what we do in the future. Can't spill the beans just yet.

Strangeworks is still working hard at SxSW on interviews and things, not to mention recovering from our launch party on Tuesday. :)

@Blue I am the only physicist at Strangeworks for now. ;)

@vzn I think a few members of the technical staff have joined but we're all still pretty busy at SxSW. I'm home with a baby so I have a bit more time to jump on start answering questions.

@vzn We're very interested in doing a meet and greet at some point.

As for the the number of users answering questions, I'm working on networking with my contacts in academia to get some quality researchers involved. However as more people becoming interested in quantum computing, I imagine this becoming the place to go for questions on the subject.

@AndrewO Thank you. That's great. I'd love to see this site succeed in the coming days.

Keep updating us :)

@heather Excellent! :D

@Blue This looks an awful lot like postselection (at first glance)

@AndrewO it will be great to try to understand the SE sponsorship model better, theres very little info on that & its uncommon on SE. re launch party sounds very fun plz feel free to share any info/ links/ pictures on that etc. reminds me of another recent "launch party" as indicated by another eminent QC engr... o_O (google!)

@AndrewO ok cool. so can you elaborate some on your own bkg/ connection to QC/ strangeworks etc? ps congrats on new addition to your family, boy or girl? :)

@vnz I have a PhD in computational physics from Texas A&M University. The bulk of my research was algorithms and benchmarking the D-Wave machines. I met Whurley last year in Japan at the Adiabatic Quantum Computing conference and we kept in touch. Just had a baby girl in January.

@Blue Is there a reason that the is Q# on topic question needs the meta-faq?

@AndrewO very interesting are you on some arxiv papers? see a AJ Ochoa there, you? arxiv.org/find/cond-mat/1/au:+Ochoa_A/0/1/0/all/0/1 did you work on a dwave benchmark paper?
