我科学家展示实现拓扑量子计算新方法
拓扑量子计算 仲费米子零模 魔术态萃取
2021/8/11
中国科学技术大学郭光灿院士团队李传锋、韩永建、许金时等人与合作者研究发现：仲费米子零模编织过程对局域噪声免疫，并且保持量子互文资源守恒，因此有望通过编织操作和魔术态萃取等手段进行普适、容错的量子计算。该成果8月9日以研究长文的形式在线发表在美国物理学会期刊《PRX量子》上，并被选为编辑推荐文章。

该研究工作提出新的数值积分方法，有效地应用于后牛顿非线性系统。在黑洞或者中子星等致密星的强引力系统下，后牛顿近似方法可以有效地描述相对论性的二体或者限制三体问题的动力学和引力波。高阶的后牛顿拉格朗日形式运动方程是高度非线性的，同时也伴随着丰富的混沌现象，传统的数值积分器在长期积分中由于舍入误差的累积，导致丧失系统的运动积分稳定性而积分结果不可靠。在前期的研究基础上，作者们提出扩大相空间拉格朗日类辛...
