标题： Infinitely fast critical dynamics: Teleportation through temporal rare regions in monitored quantum circuits

摘要： 我们研究了测量率随时间波动的可监测量子电路中的由测量诱导的相变。 测量率的空间关联涨落破坏了低测量率下的体积律相；在临界测量率下，它们导致具有“超快”动力学的纠缠相变，即时空（$x,t$）尺度的$\log x \sim t^{ψ_τ}$。 临界点处的超快动力学可以看作是无限随机性临界点的一个时空旋转版本；尽管动力学具有空间局域性，但由于测量诱导的量子隐形传态，超快的信息传播成为可能。 我们在这一临界点两侧识别出时间上的Griffiths相。 我们为这些相提供了物理解释，并通过稳定器电路中信息传播和纠缠动力学的广泛数值模拟对其进行了支持。 显示英文摘要

摘要： We consider measurement-induced phase transitions in monitored quantum circuits with a measurement rate that fluctuates in time. The spatially correlated fluctuations in the measurement rate disrupt the volume-law phase for low measurement rates; at a critical measurement rate, they give rise to an entanglement phase transition with ``ultrafast'' dynamics, i.e., spacetime ($x,t$) scaling $\log x \sim t^{ψ_τ}$. The ultrafast dynamics at the critical point can be viewed as a spacetime-rotated version of an infinite-randomness critical point; despite the spatial locality of the dynamics, ultrafast information propagation is possible because of measurement-induced quantum teleportation. We identify temporal Griffiths phases on either side of this critical point. We provide a physical interpretation of these phases, and support it with extensive numerical simulations of information propagation and entanglement dynamics in stabilizer circuits.
