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…

Q-functions as models of physical reality

Peter D. Drummond, Margaret D. Reid

We show that one may interpret physical reality as random fields in space-time. These have a probability given by the expectation of a coherent state projection operator, called th…

Testing macroscopic local realism using cat-states and Bell inequalities in time

M. Thenabadu, G-L. Cheng, T. L. H. Pham +3

We show how one may test macroscopic local realism where, different from conventional Bell tests, all relevant measurements need only distinguish between two macroscopically distin…

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…

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…
