Benchmarking Agents for Proving Theorems in Quantum Algorithms and Quantum Information

Lei Zhang, Yusheng Zhao, Yimeng Cao +10

Formal verification is becoming increasingly practical for quantum computing, yet the ability of AI agents to construct machine-checkable proofs in this domain remains unmeasured.…

Invariant Measures and Weak-Magic-Injection Asymptotics in Random Monitored Quantum Circuits

Guocheng Zhen, Xuanrong Yang, Chengkai Zhu +2

Monitored quantum circuits combine scrambling with measurement-conditioned state updates, while non-Clifford perturbations inject magic into otherwise stabilizer-compatible dynamic…

Distilling Unitary Operations: A No-Go Theorem and Minimal Realization

Jiayi Zhao, Yu-Ao Chen, Guocheng Zhen +3

Quantum gates executed on physical hardware are inevitably degraded by environmental noise. While state purification effectively distills static quantum resources, the dynamic exec…

Spectral measure of large random Helson matrices

Yanqi Qiu, Guocheng Zhen

We study the limiting spectral measure of large random Helson matrices and large random matrices of certain patterned structures. Given a real random variable $X \in L^{2+ \varepsi…

Simulation of Adjoints and Petz Recovery Maps for Unknown Quantum Channels

Chengkai Zhu, Ziao Tang, Guocheng Zhen +3

Transformations of quantum channels, such as the transpose, complex conjugate, and adjoint, are fundamental to quantum information theory. Given access to an unknown channel, a cen…
