Experimental Determination of Multi-Qubit Ground State via a Cluster Mean-Field Algorithm

Ze Zhan, Chongxin Run, Zhiwen Zong +8

A quantum eigensolver is designed under a multi-layer cluster mean-field (CMF) algorithm by partitioning a quantum system into spatially-separated clusters. For each cluster, a red…

Quantify the Non-Markovian Process with Intervening Projections in a Superconducting Processor

Liang Xiang, Zhiwen Zong, Ze Zhan +9

A Markov assumption considers a physical system memoryless to simplify its dynamics. Whereas memory effect or the non-Markovian phenomenon is more general in nature. In the quantum…

Optimization of Controlled-Z Gate with Data-Driven Gradient Ascent Pulse Engineering in a Superconducting Qubit System

Zhiwen Zong, Zhenhai Sun, Zhangjingzi Dong +13

The experimental optimization of a two-qubit controlled-Z (CZ) gate is realized following two different data-driven gradient ascent pulse engineering (GRAPE) protocols in the aim o…

A simultaneous feedback and feed-forward control and its application to realize a random walk on the Bloch sphere in a superconducting Xmon-qubit system

Liang Xiang, Zhiwen Zong, Zhenhai Sun +9

Measurement-based feedback control is central in quantum computing and precise quantum control. Here we realize a fast and flexible field-programmable-gate-array-based feedback con…
