• Title: Suppression of quantum dissipation: A cooperative effect of quantum squeezing and quantum measurement
• Authors: Yi-Ming Xia, Yi-Fei Wang, Xiao-Yun Zhang, Hai-Chao Li, Wei Xiong,
• Abstract summary: We propose a scheme for beating environment-induced dissipation in an open two-level system coupled to a parametrically driven cavity. We demonstrate that, in the presence of the cooperation, the system dynamics can be completely dominated by the effective system-cavity interaction. This work provides a generic method of dissipation suppression in a variety of quantum mechanical platforms, including natural atoms and superconducting circuits.

• Abstract: The ability to isolate a quantum system from its environment is of fundamental interest and importance in optical quantum science and technology. Here we propose an experimentally feasible scheme for beating environment-induced dissipation in an open two-level system coupled to a parametrically driven cavity. The mechanism relies on a novel cooperation between light-matter coupling enhancement and frequent measurements. We demonstrate that, in the presence of the cooperation, the system dynamics can be completely dominated by the effective system-cavity interaction and the dissipative effects from the system-environment coupling can be surprisingly ignored. This work provides a generic method of dissipation suppression in a variety of quantum mechanical platforms, including natural atoms and superconducting circuits.

  We propose how to achieve coherent manipulation and enhancement of quantum entanglement in a hybrid optomechanical system. The advantages of this system are twofold: (i) one can effectively regulate the light-mirror interactions by introducing a squeezed intracavity mode via the OPA; (ii) when properly matching the squeezing parameters between the squeezed cavity mode and the injected squeezed vacuum reservoir, the optical input noises can be suppressed completely.

We show that if the interaction is mediated by a Josephson circuit, one can have an effective dynamic corresponding to a huge enhancement of the single-photon optomechanical coupling.
