High-Precision Calibration Workflow Achieves Above CZ Gate Fidelity on a Scalable Superconducting Processor
Huili Zhang, Meiling Li, Shuang Yang +6
High-fidelity universal two-qubit gates are critical for building fault-tolerant quantum computers. In scalable superconducting processors, shortened coherence times introduce more…
Demonstration of Maxwell Demon-assistant Einstein-Podolsky-Rosen Steering via Superconducting Quantum Processor
Z. T. Wang, Ruixia Wang, Peng Zhao +8
The concept of Maxwell demon plays an essential role in connecting thermodynamics and information theory, while entanglement and non-locality are fundamental features of quantum th…
Quantum computation of conical intersections on a programmable superconducting quantum processor
Shoukuan Zhao, Diandong Tang, Xiaoxiao Xiao +7
Conical intersections (CIs) are pivotal in many photochemical processes. Traditional quantum chemistry methods, such as the state-average multi-configurational methods, face comput…
Quantum Compiling with Reinforcement Learning on a Superconducting Processor
Z. T. Wang, Qiuhao Chen, Yuxuan Du +16
To effectively implement quantum algorithms on noisy intermediate-scale quantum (NISQ) processors is a central task in modern quantum technology. NISQ processors feature tens to a…
