Strong dissipation induced coupling interaction between photons

Abstract

Dissipation is used to achieve the coupling interaction between different cavities connected by a low-Q cavity. When the dissipative rate of the central cavity is enough large, vacuum Rabi oscillation can be found. We obtain the noise spectrum which may show the unique dynamics character of the investigated system. Under the condition of strong dissipation, non-zero entanglement between photons may be observed. We also discuss the effect of thermal noise on the dynamic evolution. The work will be helpful for manipulating photonic state in noisy environment.
