Surface code logical operations on a superconducting quantum processor
Weiping Lin, Shaojun Guo, Yuwei Ma +144
Fault-tolerant quantum computation requires logical operations that manipulate encoded information while preserving quantum error-correction protection. In planar surface-code arch…
Commutator-Governed Energy Exchange in Single-Ancilla Coherent Feedback
Jun Liang Tan
A common route to ground-state preparation couples a system to one ancilla qubit, applies a conditional feedback operation, and resets the ancilla. I ask what physical quantity gov…
Probing the Limit of Heat Transfer in Inorganic Crystals with Deep Learning
Jielan Li, Zekun Chen, Qian Wang +21
Heat transfer is a fundamental property of matter. Research spanning decades has attempted to discover materials with exceptional thermal conductivity, yet the upper limit remains…
Generation of 95-qubit genuine entanglement and verification of symmetry-protected topological phases
Tao Jiang, Jianbin Cai, Junxiang Huang +152
Symmetry-protected topological (SPT) phases are fundamental features of cluster states, serving as key resources for measurement-based quantum computation (MBQC). Generating large-…
