Fewest qubits required for the discrete logarithm problem and integer factorization
According to a paper from 2002, the most efficient circuit to factor an $n$-bit integer requires $2n+3$ qubits and $O(n^{3}\lg(n))$ elementary quantum gates, assuming ideal qubits. Later on, according ...

Comparing quantum computing resources to break the DLP on elliptic curve group vs Schnorr group
Take an elliptic curve group of 256-bit prime order $n$ over a 256-bit prime field in which the Discrete Logarithm Problem is believed hard, e.g. secp256r1. Build an isomorphic Schnorr group by taking ...

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 ...

A highly space-efficient embedding of prime factorization problem using the Ising model
I hope this is not off-topic for this SE, as it directly relates to the RSA problem. My background is in quantum information and computation, so please excuse me if my notation doesn't match your ...

Is Proof-of-Authority (PoA) protocol a post quantum consensus?
Is PoA persistent against quantum attacks? If not, How can we make it post quantum?
I mean the PoA used with blockchains that delivers comparatively fast transactions through a consensus mechanism ...

Using two or more encryption algorithms together, how do we compute the strength of the final encryption?
If two or more encryption algorithms are used together, how do we compute the strength of the final encryption?
And how would the application perform against quantum computers?
The first two tables ...
