利用steering打破局部量子速度极限

Breaking local quantum speed limits with steering

Federico Centrone, Manuel Gessner

AI总结:

本文提出利用量子关联和steering,通过局部测量与经典通信打破物理过程的局部量子速度极限,为研究量子关联对动力学性质的影响开辟新途径。

摘要:

我们展示了量子关联如何仅通过共享纠缠态的双方间的局部测量和经典通信,打破物理过程的局部速度极限。通过对远程系统的测量结果进行条件化,在存在steering的情况下,可以违反由能量涨落约束量子态演化最短时间的不等式。我们的结果为研究量子关联如何影响态和可观测量的动力学性质开辟了新途径。

英文摘要:

We show how quantum correlations allow us to break the local speed limits of physical processes using only local measurements and classical communication between two parties that share an entangled state. Inequalities that bound the minimal time of evolution of a quantum state by energy fluctuations can be violated in the presence of steering by conditioning on the measurement outcomes of a remote system. Our results open up new pathways for studying how quantum correlations influence the dynamical properties of states and observables.
