Cavity-assisted squeezing of a mechanical oscillator
K. Jaehne, C. Genes, K. Hammerer +3
We investigate the creation of squeezed states of a vibrating membrane or a movable mirror in an opto-mechanical system. An optical cavity is driven by squeezed light and couples v…
Ground state cooling of a nanomechanical resonator via a Cooper pair box qubit
Konstanze Jaehne, Klemens Hammerer, Margareta Wallquist
In this paper we present a scheme for ground state cooling of a flexural mode of a nanomechanical beam incorporated in a loop-shaped Cooper-pair box (CPB) circuit. Via the Lorentz…
Implementation of the three-qubit phase-flip error correction code with superconducting qubits
L. Tornberg, M. Wallquist, G. Johansson +2
We investigate the performance of a three qubit error correcting code in the framework of superconducting qubit implementations. Such a code can recover a quantum state perfectly i…
Selective coupling of superconducting qubits via tunable stripline cavity
M. Wallquist, V. S. Shumeiko, G. Wendin
We theoretically investigate selective coupling of superconducting charge qubits mediated by a superconducting stripline cavity with a tunable resonance frequency. The frequency co…
Josephson junction qubit network with current-controlled interaction
J. Lantz, M. Wallquist, V. S. Shumeiko +1
We design and evaluate a scalable charge qubit chain network with controllable current-current coupling of neighbouring qubit loops via local dc-current gates. The network allows c…
