Violations of a Leggett-Garg inequality without signalling for a photonic qutrit probed with ambiguous measurements
Kunkun Wang, Clive Emary, Mengyan Xu +4
We realise a quantum three-level system with photons distributed among three different spatial and polarization modes. Ambiguous measurement of the state of the qutrit are realised…

Detecting topological invariants in nonunitary discrete-time quantum walks
Xiang Zhan, Lei Xiao, Zhihao Bian +5
We report the experimental detection of bulk topological invariants in nonunitary discrete-time quantum walks with single photons. The nonunitarity of the quantum dynamics is enfor…
