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…

Arbitrary d-dimensional Pauli X-Gates of a flying Qudit

Xiaoqin Gao, Mario Krenn, Jaroslav Kysela +1

High-dimensional degrees of freedom of photons can encode more quantum information than their two-dimensional counterparts. While the increased information capacity has advantages…

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…

Quantum carpets from Gaussian sum theory

Huixin Xiong, Xue-Ke Song, H. Y. Yuan +2

In many closed quantum systems, an interesting phenomenon, called quantum carpet, can be observed, where the evolution of wave function exhibits a carpet-like pattern. The mechanis…

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…

Simulating dynamic quantum phase transitions in photonic quantum walks

Kunkun Wang, Xingze Qiu, Lei Xiao +4

Signaled by non-analyticities in the time evolution of physical observables, dynamic quantum phase transitions (DQPTs) emerge in quench dynamics of topological systems and possess…
