Sub-Vacuum Jamming for Secure Communication
Sh. Barzanjeh, A. Poostindouz, B. C. Sanders
Artificial-noise jamming improves physical-layer security by degrading an eavesdropper's channel, but the injected noise also interferes with the legitimate receiver. We introduce…
Dispersive Qubit Measurement by Interferometry with Parametric Amplifiers
Sh. Barzanjeh, D. P. DiVincenzo, B. M. Terhal
We perform a detailed analysis of how an amplified interferometer can be used to enhance the quality of a dispersive qubit measurement, such as one performed on a superconducting t…
Stochastic Master Equation Analysis of Optimized Three-Qubit Nondemolition Parity Measurement
L. Tornberg, Sh. Barzanjeh, David P. DiVincenzo
We analyze a direct parity measurement of the state of three superconducting qubits in circuit quantum electrodynamics. The parity is inferred from a homodyne measurement of the re…
Steady state entanglement, cooling, and tristability in a nonlinear optomechanical cavity
S. Shahidani, M. H. Naderi, M. Soltanolkotabi +1
The interaction of a single-mode field with both a weak Kerr medium and a parametric nonlinearity in an intrinsically nonlinear optomechanical system is studied. The nonlinearities…
Controllability of optical bistability, cooling and entanglement in hybrid cavity optomechanical systems by nonlinear atom-atom interaction
A. Dalafi, M. H. Naderi, M. Soltanolkotabi
We investigate the effects of atomic collisions as well as optomechanical mirror-field coupling on the optical bistability in a hybrid system consisting of a Bose-Einstein condensa…
Quantum dynamics of an optomechanical system in the presence of Kerr-down conversion nonlinearity
S. Shahidani, M. H. Naderi, M. Soltanolkotabi +1
We study theoretically nonlinear effects arising from the presence of a Kerr-down conversion nonlinear crystal inside an optomechanical cavity. For this system we investigate the i…
