Circuit analog of quadratic optomechanics
Eun-jong Kim, J. R. Johansson, Franco Nori
We propose a superconducting electrical circuit that simulates a quadratic optomechanical system. A capacitor placed between two transmission-line (TL) resonators acts like a semi-…
Squeezed Optomechanics with Phase-matched Amplification and Dissipation
Xin-You Lü, Ying Wu, J. R. Johansson +3
We investigate the nonlinear interaction between a squeezed cavity mode and a mechanical mode in an optomechanical system (OMS) that allows us to selectively obtain either a radiat…
Iterative solutions to the steady state density matrix for optomechanical systems
P. D. Nation, J. R. Johansson, M. P. Blencowe +1
We present a sparse matrix permutation from graph theory that gives stable incomplete Lower-Upper (LU) preconditioners necessary for iterative solutions to the steady state density…
Coupling two distant double quantum dots to a microwave resonator
Guang-Wei Deng, Da Wei, Shu-Xiao Li +9
With recent advances in the circuit quantum electrodynamics (cQED) architecture, hybrid systems that couple nano-devices to microwave resonators have been developing rapidly. Here…
Toroidal qubits: naturally-decoupled quiet artificial atoms
Alexandre M. Zagoskin, Arkadi Chipouline, Evgeni Il'ichev +2
The requirements of quantum computations impose high demands on the level of qubit protection from perturbations; in particular, from those produced by the environment. Here we pro…
Optomechanical-like coupling between superconducting resonators
J. R. Johansson, G. Johansson, Franco Nori
We propose and analyze a circuit that implements a nonlinear coupling between two superconducting microwave resonators. The resonators are coupled through a superconducting quantum…
