Separate Control of Transient Leakage Exposure and Endpoint Leakage in Fast Transmon Gates
Haoran Yang, Fudong Liu, Weilong Wang +2
The paper shows that leakage during fast transmon gates can be split into transient exposure and endpoint leakage, and introduces a pulse design that separately reduces both, achie…
Tunable Nonlocal Interaction for Remote Controlled-Z Gates Between Distributed Fixed-Frequency Qubits
Benzheng Yuan, Chaojie Zhang, Haoran He +9
The paper proposes a modular superconducting quantum processor architecture that uses double‑transmon couplers and a 25‑cm coaxial cable to create a tunable nonlocal ZZ interaction…
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…
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…
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…
EDA-Q: Electronic Design Automation for Superconducting Quantum Chip
Bo Zhao, Zhihang Li, Xiaohan Yu +13
Electronic Design Automation (EDA) plays a crucial role in classical chip design and significantly influences the development of quantum chip design. However, traditional EDA tools…
