Quantum cryptography with continuous alphabet

Quantum Physics 2007-05-23 v1

Abstract

A new quantum cryptography protocol, based on all unselected states of a qubit as a sort of alphabet with continuous set of letters, is proposed. Its effectiveness is calculated and shown to be essentially higher than those of the other known protocols.
