量子光学无规行走:量子化规则与渐近性的量子模拟

Quantum Optical Random Walk: Quantization Rules and Quantum Simulation of Asymptotics

Demosthenes Ellinas, Ioannis Smyrnakis

摘要:

量子化经典随机游走的步行者+硬币部分的规则是通过将它们视为相互作用的量子系统来提供的。通过一个新的规则,将影响硬币状态的量子或经典噪声作为量子化的源,引入了量子光学随机游走(QORW)。与经典情形相比,QORW walker位置的长期渐近统计量显示出增强的扩散速率,精确地解决了。量子光学腔实现的步行提供了量子模拟的渐近统计的框架。模拟利用相互作用的二能级原子和/或激光随机脉动场与波动参数。

英文摘要:

Rules for quantizing the walker+coin parts of a classical random walk are provided by treating them as interacting quantum systems. A quantum optical random walk (QORW), is introduced by means of a new rule that treats quantum or classical noise affecting the coin's state, as sources of quantization. The long term asymptotic statistics of QORW walker's position that shows enhanced diffusion rates as compared to classical case, is exactly solved. A quantum optical cavity implementation of the walk provides the framework for quantum simulation of its asymptotic statistics. The simulation utilizes interacting two-level atoms and/or laser randomly pulsating fields with fluctuating parameters.
