论文摘要
数字量子模拟使用量子计算机的功能来确定量子系统的动力学，这超出了现代经典计算机的可计算性。众所周知，该领域的一个挑战性的任务是描述量子多体系统中非平衡动力学的描述。在这里，我们使用IBM量子计算机来模拟很少的自旋和费米管系统的非平衡动力学。我们的结果表明，通过减轻误差，噪声外推和优化初始状态准备的结合，人们可以解决现代量子设备的最重要缺点。我们模拟的系统表明，在不久的将来进行了大规模量子模拟的大规模量子模拟。
Digital quantum simulation uses the capabilities of quantum computers to determine the dynamics of quantum systems, which are beyond the computability of modern classical computers. A notoriously challenging task in this field is the description of non-equilibrium dynamics in quantum many-body systems. Here we use the IBM quantum computers to simulate the non-equilibrium dynamics of few spin and fermionic systems. Our results reveal, that with a combination of error mitigation, noise extrapolation and optimized initial state preparation, one can tackle the most important drawbacks of modern quantum devices. The systems we simulate demonstrate the potential for large scale quantum simulations of light-matter interactions in the near future.
