The Quantum Hamming Bound in Arbitrary Local Dimension
Yu-Xuan Zhang, Jing-Ling Chen
The quantum Hamming bound is the finite-length sphere-packing count for exact quantum error correction: the code dimension times the number of correctable local error patterns must…
Degeneracy Cannot Violate the Quantum Hamming Bound
Yu-Xuan Zhang, Jing-Ling Chen
The quantum Hamming bound is the standard finite-length sphere-packing bound for exact correction of arbitrary qubit errors. Whether degeneracy can evade this bound has remained un…
Peres-type Criterion of Einstein-Podolsky-Rosen Steering for Two Qubits
Yu-Xuan Zhang, Jing-Ling Chen
Quantum nonlocality manifests in multipartite systems through entanglement, Bell's nonlocality, and Einstein-Podolsky-Rosen (EPR) steering. While Peres's positive-partial-transpose…
Demonstration of Einstein-Podolsky-Rosen Steering with Enhanced Subchannel Discrimination
Kai Sun, Xiang-Jun Ye, Ya Xiao +6
Einstein-Podolsky-Rosen (EPR) steering describes a quantum nonlocal phenomenon in which one party can nonlocally affect the other's state through local measurements. It reveals an…
