Quantum Cryptography Using Single Particle Entanglement
arXiv:quant-ph/0301131 · doi:10.1103/PhysRevA.68.012324
Abstract
A quantum cryptography scheme based on entanglement between a single particle state and a vacuum state is proposed. The scheme utilizes linear optics devices to detect the superposition of the vacuum and single particle states. Existence of an eavesdropper can be detected by using a variant of Bell's inequality.
