Reconfigurable Bus-based Quantum Router for Modular Superconducting Processors
Benzheng Yuan, chaojie Zhang, Yangyang Fei +7
Scaling superconducting quantum processors requires interconnects that provide both non-local connectivity and parallel entangling operations. While current quantum routers offer g…
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…
MPI-Q: A Message Communication Library for Large-Scale Classical-Quantum Heterogeneous Hybrid Distributed Computing
Feng Wang, Junchao Wang, Zeyuan Wang +9
The classical-quantum system heterogeneity (different data characteristics, execution paradigms and synchronization mechanism etc.) renders existing distributed communication mecha…
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…
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…
