Dissipative phase transitions: Independent versus collective decay and spin squeezing
Tony E. Lee, Ching-Kit Chan, Susanne F. Yelin
We study the XY model with infinite-range interactions (Lipkin-Meshkov-Glick model) in the presence of dissipation from spontaneous decay. We show that independent and collective d…
Quantum interference between independent reservoirs in open quantum systems
Ching-Kit Chan, Guin-Dar Lin, Susanne F. Yelin +1
When a quantum system interacts with multiple reservoirs, the environmental effects are usually treated in an additive manner. We show that this assumption breaks down for non-Mark…
Entanglement tongue and quantum synchronization of disordered oscillators
Tony E. Lee, Ching-Kit Chan, Shenshen Wang
We study the synchronization of dissipatively-coupled van der Pol oscillators in the quantum limit, when each oscillator is near its quantum ground state. Two quantum oscillators w…
Dissipative transverse-field Ising model: steady-state correlations and spin squeezing
Tony E. Lee, Ching-Kit Chan
We study the transverse-field Ising model with infinite-range coupling and spontaneous emission on every site. We find that there is spin squeezing in steady state due to the prese…
Robust Distant Entanglement Generation Using Coherent Multiphoton Scattering
Ching-Kit Chan, L. J. Sham
We describe a protocol to entangle two qubits at a distance by using resonance fluorescence. The scheme makes use of the postselection of large and distinguishable fluorescence sig…
