论文摘要
我们通过采用量子力学中操作员的非交通性概念来提出量子相干性的度量。我们分析了这种非交通一致性的行为，并强调了其相似性以及与常规量子相干性测量的差异。最大非交通态的状态与传统所认为的最大相干状态相去甚远。我们认为，量子相估计算法的效率（在shor分解算法中的重要磁发）可能与非交通一致性的度量有关。
We present a measure of quantum coherence by employing the concept of noncommutativity of operators in quantum mechanics. We analyse the behaviour of this noncommutative coherence and underline its similarities and differences with the conventional measures of quantum coherence. The maximally noncommutative coherent states turn out to be far removed from the conventionally considered maximally coherent states. We argue that the efficiency of the quantum phase estimation algorithm, an important rung in the Shor factorisation algorithm, is potentially related to the measure of noncommutative coherence.
