Determination of Molecular Energies via Quantum Imaginary Time Evolution in a Superconducting Qubit System
Zhiwen Zong, Sainan Huai, Tianqi Cai +10
As a valid tool for solving ground state problems, imaginary time evolution (ITE) is widely used in physical and chemical simulations. Different ITE-based algorithms in their quant…
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…
Experimental Determination of Electronic States via Digitized Shortcut-to-Adiabaticity and Sequential Digitized Adiabaticity
Ze Zhan, Chongxin Run, Zhiwen Zong +9
A combination of the digitized shortcut-to-adiabaticity (STA) and the sequential digitized adiabaticity is implemented in a superconducting quantum device to determine electronic s…
Experimental realization of nonadiabatic geometric gates with a superconducting Xmon qubit
P. Z. Zhao, Zhangjingzi Dong, Zhenxing Zhang +3
Geometric phases are only dependent on evolution paths but independent of evolution details so that they own some intrinsic noise-resilience features. Based on different geometric…
