Versatile Multipartite Einstein-Podolsky-Rosen Steering via a Quantum Frequency Comb
Yin Cai, Yu Xiang, Yang Liu +2
Multipartite Einstein-Podolsky-Rosen steering is an essential resource for quantum communication networks where the reliability of equipment at all of the nodes cannot be fully tru…
Dynamics of transient cat-states in degenerate parametric oscillation with and without nonlinear Kerr interactions
R. Y. Teh, F. -X. Sun, R. E. S. Polkinghorne +4
A cat-state is formed as the steady-state solution for the signal mode of an ideal, degenerate parametric oscillator, in the limit of negligible single-photon signal loss. In the p…
Schrödinger cats and steady states in subharmonic generation with Kerr nonlinearities
Feng-Xiao Sun, Qiongyi He, Qihuang Gong +3
We discuss general properties of the equilibrium state of parametric down-conversion in superconducting quantum circuits with detunings and Kerr anharmonicities, in the strongly no…
Enhancement of antiferromagnetic magnon-magnon entanglement by cavity cooling
H. Y. Yuan, Shasha Zheng, Zbigniew Ficek +2
Magnon-photon coupling has been experimentally realized inside a cavity and the emerging field known as cavity spintronics has attracted significant attention for its potential doc…
Discrete time symmetry breaking in quantum circuits: exact solutions and tunneling
Feng-Xiao Sun, Qiongyi He, Qihuang Gong +3
We discuss general properties of discrete time quantum symmetry breaking in degenerate parametric oscillators. Recent experiments in superconducting quantum circuit with Josephson…
Engineering asymmetric steady-state Einstein-Podolsky-Rosen steering in macroscopic hybrid systems
Xinyao Huang, Emil Zeuthen, Qihuang Gong +1
Generation of quantum correlations between separate objects is of significance both in fundamental physics and in quantum networks. One important challenge is to create the directi…
Emergence and stability of spontaneous vortex lattices in exciton-polariton condensates
F. X. Sun, Z. X. Niu, Q. H. Gong +2
The spontaneous formation of lattice structure of quantized vortices is a characteristic feature of superfluidity in closed systems under thermal equilibrium. In exciton-polariton…
