摘要
实现通用容错量子计算是量子信息科学的关键目标。通过对量子信息编码到逻辑量子比特上，可以检测和纠正物理错误，从而实现逻辑错误率的显著降低。然而，能够轻易实现的逻辑操作集合往往受限， necessitating 使用称为“魔态”的特殊资源状态来实现通用、在经典上困难的电路。准备高保真度魔态的关键方法是进行“提炼”，从多个较低保真度输入中制造它们。本文我们在中性原子量子计算机上实现了逻辑魔态提炼。我们的做法利用动态可重构架构对大量逻辑量子比特进行编码和执行量子操作。我们展示了在d=3和d=5颜色码中对魔态进行提炼，观察到输出逻辑魔态的逻辑保真度相对于输入逻辑魔态的提升。这些实验表明了通用容错量子计算的关键构件，标志着向大规模逻辑量子处理器迈进的重要一步。
