Chip-to-chip quantum teleportation and multi-photon entanglement in silicon
Daniel Llewellyn, Yunhong Ding, Imad I. Faruque +17
Exploiting semiconductor fabrication techniques, natural carriers of quantum information such as atoms, electrons, and photons can be embedded in scalable integrated devices. Integ…
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…
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…
