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…
Separate Control of Transient Leakage Exposure and Endpoint Leakage in Fast Transmon Gates
Haoran Yang, Fudong Liu, Weilong Wang +2
Leakage to noncomputational states limits the speed of single-qubit gates in weakly anharmonic transmons. Conventional pulse-shaping methods, including derivative removal by adiaba…
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…
Tunable Nonlocal Interaction for Remote Controlled-Z Gates Between Distributed Fixed-Frequency Qubits
Benzheng Yuan, Chaojie Zhang, Haoran He +9
Scaling superconducting quantum processors toward fault-tolerant operation will likely require architectures that extend beyond monolithic chips. Modular processors connected by lo…
Fast CZ Gate via Energy-Level Engineering in Superconducting Qubits with a Tunable Coupler
Benzheng Yuan, Chaojie Zhang, Chuanbing Han +8
In superconducting quantum circuits, decoherence errors in qubits constitute a critical factor limiting quantum gate performance. To mitigate decoherence-induced gate infidelity, r…
Time-frequency-correlated Native CCZ Gate in Superconducting Circuits
Chenhui Wang, Weilong Wang, Yangyang Fei +4
Practical quantum advantage hinges on executing deep quantum circuits within the coherence limits of noisy intermediate-scale quantum processors. The absence of native, high-fideli…
