Photonic chiral state transfer near the Liouvillian exceptional point
Huixia Gao, Konghao Sun, Dengke Qu +4
As branch-point singularities of non-Hermitian matrices, the exceptional points (EPs) exhibit unique spectral topology and criticality, with intriguing dynamic consequences in non-…
Non-Hermitian Kibble-Zurek mechanism with tunable complexity in single-photon interferometry
Peng Xue, Lei Xiao, Dengke Qu +7
Non-Hermitian descriptions of quantum matter have seen impressive progress recently, with major advances in understanding central aspects such as their topological properties or th…
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…
