Relativistic Quantum Teleportation with Superconducting Circuits

Nicolai Friis, Antony R. Lee, Kevin Truong +4

We study the effects of relativistic motion on quantum teleportation and propose a realizable experiment where our results can be tested. We compute bounds on the optimal fidelity…

Breakdown of the cross-Kerr scheme for Photon Counting

Bixuan Fan, Anton F. Kockum, Joshua Combes +6

We show, in the context of single photon detection, that an atomic three-level model for a transmon in a transmission line does not support the predictions of the nonlinear polaris…

Scattering of coherent states on a single artificial atom

B. Peropadre, J. Lindkvist, I. -C. Hoi +4

In this work we theoretically analyze a circuit QED design where propagating quantum microwaves interact with a single artificial atom, a single Cooper pair box. In particular, we…

Nonclassical microwave radiation from the dynamical Casimir effect

J. R. Johansson, G. Johansson, C. M. Wilson +2

We investigate quantum correlations in microwave radiation produced by the dynamical Casimir effect in a superconducting waveguide terminated and modulated by a superconducting qua…

Giant Cross Kerr Effect for Propagating Microwaves Induced by an Artificial Atom

Io-Chun Hoi, C. M. Wilson, Göran Johansson +4

We have investigated the cross Kerr phase shift of propagating microwave fields strongly coupled to an artificial atom. The artificial atom is a superconducting transmon qubit in a…

Undoing measurement-induced dephasing in circuit QED

A. Frisk Kockum, L. Tornberg, G. Johansson

We analyze the backaction of homodyne detection and photodetection on superconducting qubits in circuit quantum electrodynamics. Although both measurement schemes give rise to back…

Generation of nonclassical microwave states using an artificial atom in 1D open space

Io-Chun Hoi, Tauno Palomaki, Göran Johansson +3

We have embedded an artificial atom, a superconducting transmon qubit, in a 1D open space and investigated the scattering properties of an incident microwave coherent state. By stu…
