In quantum teleportation, between Alice and Bob, at the end of the protocol, what happens to the qubit that Alice wanted to transmit to Bob? As described in this wiki, does "destroyed" mean that its state has been changed? And so, if Alice were to measure it, it would be different state than if Bob measured the qubit he received?

@TedShifrin I see, thanks!

What does function F : [0,1] x [0,1] -> $\mathbb{R}$ mean?
That the output of function F is a real number between 0 and 1?

@shaihorowitz Okay, I wasn't sure if I was missing something.
Sep 20, 2016 05:00
I would like to know, in Shine's answer, how he came up with the second to last line. Specifically, why k-1/2 < sqrt(k(k-1))
Sep 20, 2016 04:53
n(n+1)/2

sorry, I meant the inequality, k - 1/2 < sqrt(k(k-1))
Sep 20, 2016 04:48
@shaihorowitz would you mind elaborating? thanks

Where is $k-\frac{1}{2}$ from?

So I'm new to Arxiv.org. Just created an account. Do you think a not-so-serious paper on applying financial engineering to Team Fortress 2 would be welcome? It

@TedShifrin what are you implying here lol
Jan 31, 2015 23:00
Yes, I should probably remove that question now.
Jan 31, 2015 23:00
@TedShifrin Lol I've watched your videos and I have a copy of that text.
Jan 31, 2015 22:57
Btw, you're the Shifrin ?! Awesome

@TedShifrin :/
Jan 31, 2015 22:55
@TedShifrin Yes, that is what I computed. I wasn't confident and it confused me. Thank you.
Jan 31, 2015 22:51
@TedShifrin Okay. Me neither .-.
Jan 31, 2015 22:50
@TedShifrin Would you mind taking a look at the solution I linked? Thanks.
Jan 31, 2015 22:35
@TedShifrin Here is the solution to the problem I am working on. It relies on the fact that $OBW_2$ is $\theta$.
Jan 31, 2015 22:33
Because somehow $\alpha$ would be zero.
Jan 31, 2015 22:33
That was what I am confused about...
Jan 31, 2015 22:30
I feel pretty dumb right now. >.>

It's an isosceles triangle.

Hi, I need someone to tell me if my question is more clear now. It was put on hold.

Looking for an explanation of the math on this page: http://www.trade.tf/faq
Specifically how to calculate item prices for A,B,C,D. I don't understand where the author got the formula from.

I just started self-studying homomorphic encryption, and came across this example on Github. I was wondering if, instead of encrypting the model, could you use the Paillier scheme to encrypt the data and send it to a party with the model. The encrypted prediction is then sent back to you and you decrypt it.

Right,. when all edges have the same weight.
Jun 19, 2016 05:33
It seems possible, since there can be multiple minimum spanning trees
Jun 19, 2016 04:56
Can a graph have more than one maximum spanning tree with the same weight?

Interesting, I'm still fairly new to Qt.
To me Qt Signals/Slots are awesome. lol
Nov 1, 2014 23:15
@Morwenn Much appreciated! I didn't know about the new syntax, in fact almost everything I know about Qt pretty much comes from that one Programming with Qt4 book. ._.

"oxo"?
I'm assuming there were three won grids? For O, then X, then O right?
Nov 1, 2014 01:21
X: Simon O: Engie
It's so bugged. Look at the 2nd grid. It's clearly won, but not marked.
