... therefore come as a surprise to learn that quantum mechanical calculations are now routinely carried out to predict accurately the physical and chemical properties of systems containing many hundreds of atoms. These calculations can predict properties such as bond-lengths, phonon frequencies, elasti ...

Quantum Computing: The Risk to Existing Encryption Methods
... The purpose of this paper is not to delve deeply into the physics of quantum computers as it is considerably complicated and unnecessary for discussing the security implications of their existence. However, it is helpful to offer a brief explanation to show the relevance of quantum computing in mode ...
