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…
Effect of Stacking Order on the Electronic State of 1T-TaS
Zongxiu Wu, Kunliang Bu, Wenhao Zhang +7
New theoretical proposals and experimental findings on transition metal dichalcogenide 1T-TaS have revived interests in its possible Mott insulating state. We perform a compreh…
Reconcile the Bulk Metallic and Surface Insulating state in 1T-TaSe
Wenhao Zhang, Zongxiu Wu, Kunliang Bu +7
The transition metal dichalcogenides 1T-TaS and 1T-TaSe have been extensively studied for the complicated correlated electronic properties. The origin of different surface…
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…
