Programmable Quantum Annealing Architectures with Ising Quantum Wires
Xingze Qiu, Peter Zoller, Xiaopeng Li
Quantum annealing aims at solving optimization problems efficiently by preparing the ground state of an Ising spin-Hamiltonian quantum mechanically. A prerequisite of building a qu…
Precise Programmable Quantum Simulations with Optical Lattices
Xingze Qiu, Jie Zou, Xiaodong Qi +1
We present an efficient approach to precisely simulate tight binding models with optical lattices, based on programmable digital-micromirror-device (DMD) techniques. Our approach c…
Topology with broken parity-time symmetry
Lei Xiao, Xingze Qiu, Kunkun Wang +3
Topological edge states arise in parity-time ()-symmetric non-unitary quantum dynamics but have so far only been discussed in the -symmetry-unbroken reg…
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…
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…
