Quantum Compiler Design for Fault-Tolerant Quantum Computing
Chenghong Zhu, Jiahan Chen, Keming He +9
Scalable quantum computation is expected to rely on fault-tolerant quantum computation (FTQC), in which quantum error correction (QEC) suppresses physical errors sufficiently to su…
Logical Entangling with Phantom Codes in Hypergraph Products
Keming He, Ziao Tang, Zetong Li +2
Logical entangling gates are a major source of physical spacetime overhead in fault-tolerant quantum computation. Phantom codes reduce this cost by implementing every ordered in-bl…
A Nonstabilizerness Resource Law for Universal Quantum State Purification
Keming He, Enji Xiong, Xin Wang
Quantum state purification aims to recover higher-fidelity quantum states from multiple noisy copies and is a fundamental primitive for quantum information processing. Magic resour…
Amplitude Analysis of the Isospin-Violating Decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +759
Using events collected with the BESIII detector, we perform the first amplitude analysis of the process . The decay is dominated b…
O3LS: Optimizing Lattice Surgery via Automatic Layout Searching and Loose Scheduling
Chenghong Zhu, Xian Wu, Jiahan Chen +4
Toward the large-scale, practical realization of quantum computing, quantum error correction is essential. Among various quantum error-correcting codes, the surface code stands out…
Block Coordinate Descent for Dynamic Portfolio Optimization on Finite-Precision Coherent Ising Machines
Keming He, Yuehan Zhang, Hongshun Yao +2
Coherent Ising machines (CIMs) have emerged as specialized quantum hardware for large-scale combinatorial optimization. However, for large instances that remain challenging for cla…
