How will the world learn that Q-Day has arrived?
I wonder how the world will come to know that scalable, fully fault-tolerant quantum computers capable of running Shor's algorithm have arrived. The day when this happens has been referred to as "...

Are there any full alternatives to RSA that are quantum-resistant
By full alternatives I mean things that can do everything RSA can, namely establish secure security without privately sharing information prior. Something which AES can't do.
In other words, I'm ...

Quantum computer threats to modern cryptography
I am having a university assignment that requires me to study on the threats that quantum computer poses to modern cryptography.
At the moment, I know that modern symmetric encryption will reduce ...

New paper claims quantum polylog time attack on AES
It is well known that Grover's algorithm can solve AES in $O(\sqrt{n})$ time, which is why symmetric key length needs to be double to maintain their security level in the face of a quantum adversary. ...

Are Memory-Hard Functions de-facto quantum resistant?
Searches have returned absolutely no results on this question. With that in mind, I assume the answer is either painfully obvious ('of course quantum computers get no advantage when it comes to ...

Differences between Extractors and Privacy Amplification for Quantum Random Generators
We know that for the last step of QRNG: we need to separate quantum and classical noises from each other so we use extractors, after extractor we need privacy amplification step. At this point: if ...

Are MAC algorithms and digital signatures secure from quantum computers? If not, why?
I understand that asymmetric encryption is fundamentally deemed useless under Shor's Algorithm, and understand that symmetric encryption is somewhat quantum-resistant as long as the key-length is ...
