测量速率的时间调制是一种通过测量反作用控制开放系统动力学的强大机制。我们在一个可精确求解的最简模型中演示了该机制，该模型为处于切换晶格上的连续监测量子粒子。我们推导了周期切换和随机切换下长时间电流的精确解析表达式，揭示了共同的慢切换极限，并确定了测量诱导的、由芝诺到反芝诺主导的输运机制间的交叉，该交叉可控制电流方向。
英文摘要
Temporal modulation of the measurement rate provides a powerful mechanism for controlling open-system dynamics through measurement backaction. We demonstrate this mechanism in a minimal exactly solvable model of a continuously monitored quantum particle on a switching lattice. We derive exact analytical expressions for the long-time current under both periodic and stochastic switching, revealing a common slow-switching limit and identifying a measurement-induced crossover between Zeno- and anti-Zeno-dominated transport regimes that controls the direction of the current.
