摘要

最近有人指出，IBM量子计算机的一个突出应用是逆转时间之箭(Lesovik et al.， 2019)。在一个双量子位系统耦合到一个共同的结构储层中，在零温度下探索了这种可能性。结果表明，在遥远的过去和遥远的未来，量子态的居群率都是相同的。存在噪声的双量子位系统可以逆转时间之箭。

Population rate of quantum states and the reverse of the arrow of time

Recently it has been pointed out that an outstanding application of an IBM quantum computer is to reverse the arrow of time (Lesovik et al., 2019). It is explored such a possibility in a two qubits system coupled to a common structured reservoir at zero temperature. It is shown that population rates of the quantum states become the same both towards the remote past and towards the remote future. A two qubits system in presence of noise can reverse the arrow of time.
