For decades, the quantum threat to RSA and ECC encryption has been tied to Shor’s algorithm and the assumption that we would need million-qubit quantum computers to make it practical. A newly ...

The amount of quantum computing power needed to crack a common data encryption technique has been reduced tenfold. This makes the encryption method even more vulnerable to quantum computers, which may ...

Will quantum computers crack cryptographic codes and cause a global security disaster? You might certainly get that impression from a lot of news coverage, the latest of which reports new estimates ...

Keith Martin receives funding from EPSRC. Will quantum computers crack cryptographic codes and cause a global security disaster? You might certainly get that impression from a lot of news coverage, ...

Quantum computers could crack a common data encryption technique once they have a million qubits, or quantum bits. While this is still well beyond the capabilities of existing quantum computers, this ...

The RSA algorithm is based on the mathematical difficulty of factoring the product of two large prime numbers. It involves generating a public and private key pair, where the public key is used for ...

This is a pure (and very very simple) java implementation of the RSA algorithm. One file to show you how RSA works (Euler's formula and Euclid's algorithm).

It’ll still be a while before quantum computers become powerful enough to do anything useful, but it’s increasingly likely that we will see full-scale, error-corrected quantum computers become ...
