Photonic realization of erasure-based nonlocal measurements
Wei-Wei Pan, Xiao-Ye Xu, Eliahu Cohen +6
Relativity theory severely restricts the ability to perform nonlocal measurements in quantum mechanics. Studying such nonlocal schemes may thus reveal insights regarding the relati…
Direct measurement of a nonlocal entangled quantum state
Wei-Wei Pan, Xiao-Ye Xu, Yaron Kedem +8
Entanglement and wave function description are two of the core concepts that make quantum mechanics such a unique theory. A method to directly measure the wave function, using Weak…
Measurements of nonlocal variables and demonstration of the failure of the product rule for a pre- and postselected pair of photons
Xiao-Ye Xu, Wei-Wei Pan, Qin-Qin Wang +9
We report the first implementation of the von Neumann instantaneous measurements of nonlocal variables which becomes possible due to technological achievements in creating hyperent…
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…
