QCORE: A Quantum-Control-Oriented Real-Time Execution Architecture with Extensible Closed-Loop Services and Shared AI Acceleration
Heyue Li, Yanshu Guo, Qichun Liu +3
Scalable quantum processors require control, readout, feedback, calibration, and error correction to coexist under bounded latency and shared-resource constraints, whereas existing…
Collective Coherent Perfect Absorption in a Synthetic Photon-Phonon Lattice
Sihan Wang, Qichun Liu, Bo Song +3
Coherent perfect absorption (CPA) has emerged as a powerful paradigm for controlling classical and quantum light, and has been demonstrated across a broad range of physical platfor…
Dissipative acousto-mechanical parametric interface between high-overtone acoustics and flexural phonons
Xun Ji, Huanying Sun, Longhao Wu +4
High-overtone bulk acoustic wave resonators (HBARs) promise advanced phononics, yet achieving nonlinearity remains challenging. We demonstrate a radiation-pressure-type parametric…
Observation of attractor transitions in active magnon-polaritons under microwatt drives
Hao Wu, Qichun Liu, Yuanbin Fan +2
Magnon-polaritons provide a room-temperature platform for investigating nonlinear cavity quantum electrodynamics in the microwave domain, but experimentally observing controlled tr…
CO-QLink: Cryogenic Optical Link for Scalable Quantum Computing Systems and High-Performance Cryogenic Computing Systems
Zheng Chang, Siqi Zhang, Wenqiang Huang +8
Cryogenic systems necessitate extensive data transmission between room-temperature and cryogenic environments, as well as within the cryogenic temperature domain. High-speed, low-p…
Superior Frequency Stability and Long-Lived State-Swapping in Cubic-SiC Mechanical Mode Pairs
Huanying Sun, Yanlin Chen, Qichun Liu +4
The multimode cavity optomechanical system offers versatile applications including state transduction, coherent interconnection, and many-body simulations. In this study, we develo…
