论文摘要
兴奋至Rydberg状态的光学捕获原子的阵列最近已成为量子模拟和计算的竞争物理平台，在该平台中，已经证明了高保真状态的制备和读数，量子逻辑门以及超过100码的控制量子动力学。这些系统现在正在接近具有数百吨和实际的数千个具有较低错误率的多Quarit门的可靠量子计算，应首次达到较低的误差率。在本文中，我们概述了Rydberg Quantum工具箱，强调了编码Qubits，执行量子操作和工程量子多体型Hamiltonians的高度灵活性。然后，我们回顾有关高保真量子操作和逻辑门以及多体制方案中的量子模拟的最先进的。最后，我们讨论了特别适合Rydberg平台的计算方案，以及通用通用量子模拟器和量子计算机的剩余挑战。
Arrays of optically trapped atoms excited to Rydberg states have recently emerged as a competitive physical platform for quantum simulation and computing, where high-fidelity state preparation and readout, quantum logic gates and controlled quantum dynamics of more than 100 qubits have all been demonstrated. These systems are now approaching the point where reliable quantum computations with hundreds of qubits and realistically thousands of multiqubit gates with low error rates should be within reach for the first time. In this article we give an overview of the Rydberg quantum toolbox, emphasizing the high degree of flexibility for encoding qubits, performing quantum operations and engineering quantum many-body Hamiltonians. We then review the state-of-the-art concerning high-fidelity quantum operations and logic gates as well as quantum simulations in many-body regimes. Finally, we discuss computing schemes that are particularly suited to the Rydberg platform and some of the remaining challenges on the road to general purpose quantum simulators and quantum computers.
