While there's no reason why a computer should not eventually be manufacturable, Prof. Morello believes this in itself isn't the end of the story. "Most people think the ultimate outcome from a century of research is that we have a computer that works, and it would be a machine that never existed before which can solve problems that could ...

Quantum Computing: The Risk to Existing Encryption Methods

threat of to RSA and other popular methods is discussed, and safe alternatives that can be useful in the post- era are proposed. The basis of modern security relies on methods that are practically impossible, but theoretically possible, to break. The most common is the Rivest-Shamir-Adleman (RSA) cryptosystem, which takes advantage of the ...

An Overview Of Quantum Computing's Possible Impact On Cryptography

To not lose the race between cryptography and the computers, NIST initiated a competition in November 2016 to select computer- cryptographic methods. Of the 82 candidates submitted, 69 were accepted, with 64 effectively entering the race - including 45 or key transport methods and 19 signature methods (Hagemeier, 2019, p. 634).

The Impact of Quantum Computing on Cryptography - ScienceDirect

A computer operates on all qubit values simultaneously; a capability known as parallelism. The computational speed of a computer increases exponentially with the number of qubits, so that an n-qubit computer can compute 2n values at once. This extraordinary speed is attributed to the entangled state in which a ...
