Actually you can't compose quantum crypto protocols like you can classical ones - the composed protocol needs a new security analysis. Entanglement across protocols often kills the composition! Interestingly (to me!) it took a while in

ChatGPT suggests (and cites your paper): Give the humans an order 1,2,3,…, and let a referee read them in that order. Person k tosses one fair coin and reports H/T. The referee stops at the first time the reported heads exceed the repo

Yeah sorry, pretty vague, and I'm not sure what the "rules" precisely should be. Roughly I mean something that involves an infinite number of humans but where the workload per human is finite (perhaps only in expectation?) an

Asher Peres told me that Bill Wootters should be given 99% of the credit for the teleportation discovery (and this is in the context that most of us around at the time presumed the majority of the credit should go to Peres and Wootters who

Fun read! I have an extremely vague question; Is there one of these "stupid" ways of computing pi that doesn't involve an infeasible (to humans) infinity? I'm comparing to the "have pick people random integers and t

This was interesting thanks - makes me wish I had the time to study your examples. But of course I don't, without just turning to an LLM.... If for any of these topics you do manage to get a summary you'd agree with from a (futu

This proposal requires exponential energy! But you can factorize numbers with only one photon (a tiny amount of energy). Oh yeah, you’ll need an exponential number of modes (you just build a very-low-loss interferometer that does the unit

I suspect you are right - but multiple Nobel prizes have gone to people who got there only very slightly ahead of others in the race. Would be tough to argue that there are many prizes which are for work that wouldn't have been done wi

Surely Wofram deserves the Nobel as much as Hopfield and Hinton? Not for this stuff of course (which I doubt many take seriously), but because he also provided us with an amazing computational tool without which physics would be very far be

It is possible to make quantitative statements that I think capture many of the intuitions you assert. Here was one attempt: https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.10... That particular pro

Is this known to be true? Its obviously not true for arbitrary irrational numbers

Random question from a very-much-not-computer savvy person on the off chance someone cares to answer: If a tiny charge was levied every time a webserver delivered a page to me would it cure this kind of problem? I'm imagining e.g. my b

Given access to repeated uses of a coin of unknown bias "p" (which is not 0 or 1) you can (eventually) always generate a new coin flip with bias given (exactly) by: 1. 1/2 (i.e fair - von Neumann) 2. p^2 3. p^2/(p^2+(1-p

Perhaps it helps to imagine someone had a "screwy thumb" and the coin only precesses when they "flip" it (in fact people can train themselves to do this, and its very difficult for you, the sucker, to see in the air th

Unfortunately I don't have a github account, but in case you will take a report from here. In this paper of mine: https://ar5iv.labs.arxiv.org/html/2303.05514 The references come inline and not well separated from

Its a great start! It seems to be using the bibtex tags for the inline citations. They don't stand out clearly enough for my liking, and they also have me worried: have I ever used a tag for someones paper like "XXXnonsense"

Perhaps I would quit if things deteriorated to the point I was seriously considered the best option for such!

Presumably talking to the wind here as this thread is old, but nonlocal hidden variables do not break causality! This can be seen explicitly in Bell's trivial model, where the state of a system is just the regular quantum state plus a

Can't resist mentioning my personal favorite expansion of a sqrt: sqrt(1-x) = 1- \sum_n C(n)/2^(2n+1) x^(n+1) where x is in (0,1) and C(n)=binomial(2n,n)/(n+1) is the n'th catalan number. [Learned this from http:/&

Great - yet another misaligned incentive to throw into the often stressful mix of how lead authorship should be determined!

Agree with this - the jury is still out on "reality" or otherwise of a wavefunction, and people expend their "real" research efforts differently according to their opinion! Saying "well everything is just mathematic

There is a fun generalization of the game. Assume the penny has (unknown) bias p. You want to output a new flip with bias some function f(p). So f(p)=1/2 is what you described, ie how to get a fair flip. For some functions it can be ev

Not OP, and I don't have time (hah) to do the calculation but a rough rule of thumb is that if you take a "normal size" of a quantity (mass, speed, etc) then relativistic effects become measurable when you scale it by c^2, ie

Thanks for buying! Any money I make eventually works its way back to Malawi where I grew up, so it not going to be squandered :) A few weeks ago a high school physics teacher who used the book for some extension classes sent me some python

Actually its not quite that simple. The approaches are "equivalent" (in terms of operational/statistical predictions) but not "isomorphic" (even if we restrict the regular linear algebra approach to the same gates a
