Exact Clifford Optimality for Two-Sided Locally Randomized Classical Shadows
Xiaotian Nie, Tao Zhang, Yadong Wu +1
Entangling measurements can reduce the statistical cost of learning many-body correlations. We study Pauli strings with full support on a specified -qubit region using classical…
Experiment-compatible measurement--feedback quantum state preparation with reinforcement learning
Xiaotian Nie, Tao Zhang, Linghui Chen
Ground-state preparation is a critical task in quantum simulation and quantum computing, as it enables the study of correlated phases and the generation of entangled resource state…
AI-Enabled Decoding of Qubit Loss for Quantum Error-Correcting Codes
Yuqing Wang, Xiaotian Nie, Jiale Dai +4
Qubit loss is a major source of error in quantum computation, as it invalidates the algebraic structure of the standard stabilizer formalism for quantum error-correcting codes. On…
An Algorithm for Fast Assembling Large-Scale Defect-Free Atom Arrays
Tao Zhang, Xiaodi Li, Hui Zhai +1
It is widely believed that tens of thousands of physical qubits are needed to build a practically useful quantum computer. Atom arrays formed by optical tweezers are among the most…
