Experimental entropic test of state-independent contextuality via single photons
Dengke Qu, Pawel Kurzynski, Dagomir Kaszlikowski +5
Recently, an inequality satisfied by non-contextual hidden-variable models and violated by quantum mechanics for all states of a four-level system has been derived based on informa…
Experimental orthogonalization of highly overlapping quantum states with single photons
Gaoyan Zhu, Orsolya Kalman, Kunkun Wang +6
We experimentally realize a nonlinear quantum protocol on single-photon qubits with linear optical elements and appropriate measurements. The quantum nonlinearity is induced by pos…
Conserved quantities in parity-time symmetric systems
Zhihao Bian, Lei Xiao, Kunkun Wang +6
Conserved quantities such as energy or the electric charge of a closed system, or the Runge-Lenz vector in Kepler dynamics are determined by its global, local, or accidental symmet…
Observation of critical phenomena in parity-time-symmetric quantum dynamics
Lei Xiao, Kunkun Wang, Xiang Zhan +5
We experimentally simulate non-unitary quantum dynamics using a single-photon interferometric network and study the information flow between a parity-time (PT)-symmetric non-Hermit…
Higher winding number in a non-unitary photonic quantum walk
Lei Xiao, Xingze Qiu, Kunkun Wang +6
Topological matter exhibits exotic properties yet phases characterized by large topological invariants are difficult to implement, despite rapid experimental progress. A promising…
Observation of emergent momentum-time skyrmions in parity-time-symmetric non-unitary quench dynamics
Kunkun Wang, Xingze Qiu, Lei Xiao +5
Topology in quench dynamics gives rise to intriguing dynamic topological phenomena, which are intimately connected to the topology of static Hamiltonians yet challenging to probe e…
