Recovering Readout-Limited Fisher Information in Superconducting-Qubit Magnetometry with Squeezed Microwaves
M. -R. Yun, Y. -J. Qu, Zheng Shan +3
The performance of superconducting-qubit magnetometers depends not only on magnetic-field encoding during Ramsey interrogation, but also on how efficiently the encoded information…
QMClaw: A Scalable General-purpose Framework for Quantum Measurement and Control
Zhiqiang Fan, Haoran He, Ping Lv +12
As quantum computing continues to scale, quantum measurement and control (QMC) are increasingly constrained by calibration workflow complexity and by requirements for low-latency e…
Transducer leakage error suppression using invariant-based shortcut
Shi-Qiang Qiao, Zheng Shan, Xue-Ke Song +3
We present a method for suppressing transducer leakage errors in spin-superconducting hybrid quantum systems with the theory of optimal invariant-based shortcut. By mediated virtua…
Raw-Curve Quantum Fingerprints: A Mahalanobis Authentication Framework with Drift Early Warning and Adversarial Detection
Geyuyan Ma, Xiangdong Meng, Yangyang Fei +6
Quantum cloud platforms are poised to deliver powerful computing capabilities, but users have no direct means to verify which physical device executes their workload. This lack of…
HI-HCQC: A Tightly-Coupled Hardware Interface with High-Efficiency Communication for Hybrid Classical-Quantum Computing
Shibo Liang, Junchao Wang, Zeyuan Wang +5
Hybrid classical-quantum computing requires frequent data exchange between classical processors and quantum control hardware. However, existing superconducting quantum control syst…
Modeling and Resource Optimization for Quantum Oracles
Zhihang Li, Bo Zhao, Chuanbing Han +6
Quantum oracles are fundamental building blocks of many quantum algorithms, and their resource consumption directly affects performance, yet structured description and complexity a…
