IBM 硬件上量子核几何存活率测试

研究人员在 IBM 量子硬件上研究了四量子比特量子核内几何信息的存活情况。该研究聚焦于一种特定的冻结 ZZ 特征映射核,并分析了其在三种执行配置下的性能:基线、动力学解耦和门旋转。结果表明,虽然格拉姆矩阵在执行后普遍存活并能在很大程度上保留状态向量几何,但门旋转被证明是最忠实的方法。然而,最忠实配置与目标标签的对齐度最低,这表明在当前的量子机器学习研究中,实现保真度与任务相关性之间存在脱节。 AI

    基于状态向量的四量子比特ZZ量子核在IBM量子硬件上的几何存活:三种执行配置的固定子集诊断

    arXiv:2607.20377v1 Announce Type: cross Abstract: Quantum-kernel methods encode a dataset's geometry in a Gram matrix, so learning claims on hardware kernels assume the intended geometry survives execution. We measure that survival for one frozen four-qubit ZZ feature-map kernel …
