Low-cost algorithm-to-execution framework for surface-code quantum computing
Yunxin Tang, Zixuan Huo, Junxiang Huang +12
The execution of useful quantum algorithms on fault-tolerant processors requires more than a mapping from logical gates to encoded operations: the spatial organization, non-Cliffor…
Constant-depth global shadow estimation
Qingyue Zhang, Zhou You, Dayue Qin +3
Reliable and scalable readout strategies are essential for quantum technologies. As quantum processors grow, extracting useful information must remain feasible without measurement…
Ultra-Precise Quantum Projective Designs in Constant Depth
Qingyue Zhang, Junjie Chen, Zhou You +1
Random quantum objects are powerful resources for quantum information processing, yet exact Haar randomness is costly and typically unnecessary. We introduce an explicit sparse com…
Quantum-classical crossover in fault-tolerant quantum dynamics simulation
Jinzhao Sun, Bozhen Zhou, Jue Xu +28
While quantum computers promise to solve classically intractable problems, identifying the point at which fault-tolerant quantum computation outperforms the best classical algorith…
A Three-Layer Architecture for Fault-Tolerant Quantum Computing
Zhirao Wang, Zhou You, Yiming Huang +4
Fault tolerance is an indispensable prerequisite for constructing large-scale universal quantum computers. Drawing philosophies from classical computer architecture, this paper pre…
Phase shadow: A noise-tolerant path to global quantum property estimation
Qingyue Zhang, Dayue Qin, Zhou You +3
Measuring global quantum properties-such as the fidelity to complex multipartite states-is both an essential and experimentally challenging task. Classical shadow estimation offers…
