Thermal aliases in quantum noise: sampling clocks and pulse widths
Zi-Xuan Wang, Xiu-Hao Deng
Can collective quantum-noise measurements distinguish different mode temperatures from one common temperature when the coupling spectrum is unknown? For stationary Gaussian oscilla…
All-Microwave Multiqubit Gates
Guanqi Wang, Yao Song, Peng-Bo Li +1
Implementing high-fidelity multiqubit gates is critical for reducing circuit depth in near-term quantum processors and fault-tolerant architectures. However, realizing multiqubit i…
A Memory-Magic Exchange Law in Streaming Clifford+T Compilation
Jinze Yang, Yangyang Li, Xiu-Hao Deng
A phase that reaches a fault-tolerant processor in additive pieces can be remembered until the last piece arrives, or executed on arrival: the first option costs classical memory c…
Do Quantum AIs Dream in Paths? Path-Integral Slow Thinking through Grover Interference
Xiansheng Cai, Xiu-Hao Deng, Kun Chen
Reinforcement learning with verifiable rewards enables large language models to think slowly, but the same training can induce policy collapse: probability concentrates onto a few…
Robust CZ gate against flux line memory
Yao Song, Xiu-Hao Deng
High-fidelity CZ gates are central to superconducting quantum processors, but implementations based on flux tuning are still sensitive to pulse distortion. Conventional predistorti…
Measurement-Free Toric-Code Memory in Array Globally Controlled Rydberg Array
Han Wang, Yusheng Zhao, Xiuhao Deng +1
The central prerequisite of any fault-tolerant quantum architecture is a quantum memory: a block of encoded physical qubits whose logical state is actively preserved against noise…
Universal Robust Quantum Gates via Doubly Geometric Control
Hai Xu, Tao Chen, Junkai Zeng +5
Geometric quantum computation offers a potential route to fault-tolerant quantum information processing by exploiting the global nature of geometric phases. However, achieving cont…
Pareto Front Engineering of Dynamical Sweet Spots in Superconducting Qubits
Zhen Yang, Shan Jin, Yajie Hao +4
Operating superconducting qubits at dynamical sweet spots (DSSs) suppresses decoherence from low-frequency flux noise. A key open question is how long coherence can be extended und…
