On-demand generation of shallow silicon vacancy in silicon carbide
Jun-Feng Wang, Qiang Li, Fei-Fei Yan +10
Defects in silicon carbide have been explored as promising spin systems in quantum technologies. However, for practical quantum metrology and quantum communication, it is critical…
Dynamic-Disorder-Induced Enhancement of Entanglement in Photonic Quantum Walks
Qin-Qin Wang, Xiao-Ye Xu, Wei-Wei Pan +6
Entanglement generation in discrete time quantum walks is deemed to be another key property beyond the transport behaviors. The latter has been widely used in investigating the loc…
Measuring the winding number in a large-scale chiral quantum walk
Xiao-Ye Xu, Qin-Qin Wang, Wei-Wei Pan +8
We report the experimental measurement of the winding number in an unitary chiral quantum walk. Fundamentally, the spin-orbit coupling in discrete time quantum walks is implemented…
Measuring a Dynamical Topological Order Parameter in Quantum Walks
Xiao-Ye Xu, Qin-Qin Wang, Markus Heyl +9
Quantum processes of inherent dynamical nature, such as quantum walks (QWs), defy a description in terms of an equilibrium statistical physics ensemble. Up to now, it has remained…
Achieving Heisenberg-scaling precision with projective measurement on single photons
Geng Chen, Lijian Zhang, Wen-Hao Zhang +11
It has been suggested that both quantum superpositions and nonlinear interactions are important resources for quantum metrology. However, to date the different roles that these two…
Experimental self-testing of entangled states
Wen-Hao Zhang, Geng Chen, Xing-Xiang Peng +12
Quantum entanglement is the key resource for quantum information processing. Device-independent certification of entangled states is a long standing open question, which arouses th…
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…
