An Attack to Quantum Cryptography from Space
Igor V. Volovich ;
Date 13 Dec 2000
Subject quant-ph
AbstractThe promise of secure cryptographic quantum key distribution schemes is based on the use of quantum effects in the spin space. We point out that in fact in many current quantum cryptography protocols the space part of the wave function is neglected. However exactly the space part of the wave function describes the behaviour of particles in ordinary real three-dimensional space. As a result such schemes can be secure against eavesdropping attacks in the abstract spin space but could be insecure in the real three-dimensional space. We discuss an approach to the security of quantum key distribution in space by using Bell’s inequality and a special preparation of the space part of the wave function.
