We suggest that propagation of nonclassical light in lattices of optical waveguides can provide a laboratory tool to simulate quantum decoherence phenomena with high non-Markovian features. As examples, we study decoherence of optical Schrödinger cats in a lattice that mimics a dissipative quantum harmonic oscillator coupled to a quantum bath, showing fractional decoherence in the strong coupling regime, and Bloch oscillations of optical Schrödinger cats, where damped revivals of the coherence can be observed.
我们提出，在光导波的晶格中传播非经典光，可以提供一个实验室工具来模拟具有高非马尔可夫特征的量子退相干现象。作为例子，我们研究了在模拟耗散量子谐振子与量子浴耦合的晶格中的光学薛定谔猫的退相干，在强耦合 regime 中表现出分数退相干，并且观察到光学薛定谔猫的布洛赫振荡，其中可以观察到相干的阻尼恢复。
