量子密码中相对论性量子态的可分辨性

On the Distinguishability of Relativistic Quantum States in Quantum Cryptography

R. Laiho, S. N. Molotkov, S. S. Nazin

摘要:

相对论量子场论对量子态的可解释性施加了额外的基本限制。由于闵可夫斯基时空中量子场态的不可避免的离域性,正交态的可靠(单位概率)可验证性形式上需要无限的时间。对于时间有限的密码协议,后者意味着即使在理想的通信信道中也存在有效的"噪声“,因为量子场态的非局部化性。

英文摘要:

Relativistic quantum field theory imposes additional fundamental restrictions on the distinguishability of quantum states. Because of the unavoidable delocalization of the quantum field states in the Minkowski space-time, the reliable (with unit probability) distinguishability of orthogonal states formally requires infinite time. For the cryptographic protocols which are finite in time the latter means that the effective ``noise'' is present even in the ideal communication channel because of the non-localizability of the quantum field states.
