Quantum key distribution with the deterministic preparation and detection of quantum states

  • S. N. Molotkov
Quantum Information Science

Abstract

A new deterministic optical scheme has been proposed for preparing and detecting quantum states in quantum cryptography. This scheme makes it possible to quadruple the efficiency of the existing systems under the other conditions being equal. Thus, the efficiency of the optical part is increased to the maximum for the preparation and detection of quantum states.
