论文摘要
我们对IBMQ处理器中的频镜两冲程热发动机进行了量子模拟。该系统由使用变异量子热量算法在不同温度下在不同温度下制备的量子自旋链组成，该量子自旋链在其边界处连接起来。动力学在热量和工作冲程之间交替，可以使用独立的量子电路分别设计。结果表明，与理论预测相吻合，将IBMQ展示为研究量子制度中热力学的有力工具，以及在现实世界中量子计算机中的变异量子算法的实施。它还打开了模拟跨链几何和相互作用的量子热传输的可能性。
We put forth a quantum simulation of a stroboscopic two-stroke thermal engine in the IBMQ processor. The system consists of a quantum spin chain connected to two baths at their boundaries, prepared at different temperatures using the variational quantum thermalizer algorithm. The dynamics alternates between heat and work strokes, which can be separately designed using independent quantum circuits. The results show good agreement with theoretical predictions, showcasing IBMQ as a powerful tool to study thermodynamics in the quantum regime, as well as the implementation of variational quantum algorithms in real-world quantum computers. It also opens the possibility of simulating quantum heat transport across a broad range of chain geometries and interactions.
