论文摘要
我们表明,当前的噪声量子计算机是通用开放系统中量子多体动力学模拟的理想平台。我们使用IBM量子计算机作为实验平台来证明这一点,以证实[Phys的理论预测。 Rev. Lett.124,100604(2020)]在涉及不同数量的量子的多体观察物的休闲时间尺度上的新兴层次结构。使用不同的协议,我们利用负责门误差的机器的内在耗散,实施对局部耗散相互作用的通用(即无结构)的量子模拟。
We show that current noisy quantum computers are ideal platforms for the simulation of quantum many-body dynamics in generic open systems. We demonstrate this using the IBM Quantum Computer as an experimental platform for confirming the theoretical prediction from [Phys. Rev. Lett.124, 100604 (2020)] of an emergent hierarchy of relaxation timescales of many-body observables involving different numbers of qubits. Using different protocols, we leverage the intrinsic dissipation of the machine responsible for gate errors, to implement a quantum simulation of generic (i.e. structureless) local dissipative interactions.
