This claims to be well-documented and secure by default, but I cannot find a link to the documentation (or is it just the README)? What actual algorithm is used for encryption and for signing? The README has a major red…
Oh absolutely, the theory behind QKD is fascinating! And I do think that some day there may be actually secure practical implementations, maybe even ones that are practical for more than a few niche applications. But…
Yes, otherwise how would you know you are indeed communicating with that party? Otherwise the standard Person-in-the-Middle attack would apply: Eve (claiming to be Bob) first runs a full protocol session (quantum +…
> Rather, device-independent quantum key distribution allows you to scale back the assumptions on your implementation to a well-motivated, minimal set. To me, this is already intriguing enough without the need for…
The article suggests that quantum key distribution (QKD) is a replacement for a courier, but that is not true. Distributing an initial small secret key (which allows authenticity of the post-processing of the quantum…
That's simply a logical fallacy: P => Q does not imply (not P) => (not Q). Here: "If it is inaccurate, then it is wrong" does not imply "If it is accurate, then it is right."
No configuration, curve or key-size would protect any of the asymmetric crypto mentioned in the book from quantum computing. You really have to switch to something mentioned in the post-quantum chapter.
This take is rather naive. Those RSA factoring records were done by a large international team of researchers, using well established algorithms and decades of work on implementing those methods as fast as possible. The…
It's broken for me, thanks to the "responsive" design. When the browser window occupies half my screen (1920x1080px), the top-right menus (bell, plus, profile) get replaced with only a bell icon. How am I supposed to…
That is apples to oranges, you're citing a lattice reduction algorithm? Maybe you meant the number field sieve https://en.wikipedia.org/wiki/General_number_field_sieve? In that case the answer is: never. We've tried to…
This study considers seven semi-primes (without justification why these seven) and reports an average(?) runtime of factoring each with D-Wave. No conclusions should be drawn on so few data-points. The proposed "Block…
It's strange that the authors pick integer factorization as the problem to solve on their machine. Although their machine may provide a speedup for optimization problems, these speedups are not relevant for the problem…
Hi Scott, Do you think we will see a Quantum Winter (or even several), similar to how we've had several AI Winters? We see tremendous amounts of funding in academia (and also industry) to build ambitious projects that…
