光波导晶格退相干的量子模拟

Quantum simulation of decoherence in optical waveguide lattices

Stefano Longhi

摘要:

我们认为,非经典光在光波导晶格中的传播可以提供一个实验室工具来模拟具有高度非马尔可夫特征的量子退相干现象。作为例子,我们研究的退相干的光学薛定谔猫在晶格中,模仿一个耗散的量子谐振子耦合到一个量子浴,显示分数退相干的强耦合制度,和布洛赫振荡的光学薛定谔猫,阻尼复苏的相干性可以观察到。

英文摘要:

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.
