Millikelvin digital-to-analog converter for superconducting quantum processors
Ruizi Hu, Zongyuan Li, Zhancheng Yao +19
Scaling superconducting quantum processors is increasingly constrained by the wiring, heat load, and calibration overhead associated with delivering high-resolution analog signals…
Scalable Fluxonium Quantum Processors via Tunable-Coupler Architecture
Ze Zhan, Zishuo Li, Fei Wang +24
Superconducting quantum processors have largely converged on transmon-based architectures, while alternative qubit modalities with intrinsic error protection have lacked a demonstr…
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…
