单模双光子（Qutrits）的操作性双光子性条件
Operationalistic Orthogonality Condition for Single-Mode Biphotons (Qutrits)
摘要：
研究了单模双光子的任意偏振态。给出了这些态正交性的可操作性判据。它可以从一组正交于它的双光子中分离出一个具有任意偏振度的双光子，这是实现基于三能级系统的量子密码协议所必需的。对这一判据的实验检验相当于观察到了任意偏振态双光子的双光子相干效应。
英文摘要：
An arbitrary polarization state of a single-mode biphoton is considered. The operationalistic criterion is formulated for the orthogonality og these states. It can be used to separate a biphoton with an arbitrary degree of polarization from a set of biphotons orthogonal to it. This is necessary fro the implementation of quantum cryptography protocol based on three-level systems. The experimental test of this criterion amounts to the observation of the anticorrelation effect for a biphoton with an arbitraty polarization state.
