Generation of entanglement via squeezing on a tripartite-optomechanical system

نویسندگان

چکیده

We introduce a new strategy to regulate the quantum entanglement in dispersive-hybrid system where qubit is directly coupled cavity and resonator. A dramatic transition takes place by only tuning squeezing parameters associated with vibrational mode. As amplitude becomes larger, maximal abruptly falls zero at specific phases. It also possible generate for bipartitions from qubit-cavity-resonator after applying this strategy. Entangled qubit-cavity states are created through squeezing, even though there no direct interaction between them. analyze effect of atomic, optical, losses on entanglement. Finally, we discuss future realizations implement all these ideas promote further studies generalize concept monogamy tripartite systems outside qubit-composite states, particular, $(2 \otimes 2 n)$-dimensional systems.

A Study of Entanglement and Squeezing of

We study entanglement and squeezing of a cluster of spin systems under the influence of the two-axis countertwisting Hamiltonian. The squeezing parameters given by Wineland et al and also by Kitagawa et al. are chosen as the criteria of spin squeezing. The criterion of pairwise entanglement is chosen to be the concurrence and that of the bipartite entanglement the linear entropy. We also define...

Cooling and squeezing via quadratic optomechanical coupling

We explore the physics of optomechanical systems in which an optical cavity mode is coupled parametrically to the square of the position of a mechanical oscillator. We derive an effective master equation describing two-phonon cooling of the mechanical oscillator. We show that for high temperatures and weak coupling, the steady-state phonon number distribution is nonthermal (Gaussian) and that e...

Steady-state mechanical squeezing in a double-cavity optomechanical system

We study the physical properties of double-cavity optomechanical system in which the mechanical resonator interacts with one of the coupled cavities and another cavity is used as an auxiliary cavity. The model can be expected to achieve the strong optomechanical coupling strength and overcome the optomechanical cavity decay, simultaneously. Through the coherent auxiliary cavity interferences, t...
