We theoretically study a circuit QED architecture based on superconducting flux qubit directly coupled to the center conductor of coplanar waveguide transmission-line resonator. As already shown experimentally [A. A. Abdumalikov, Jr. et al., Phys. Rev. B 78, 180502(R) (2008)], strong coupling regime cavity can readily be achieved by optimizing local inductance resonator in vicinity qubit. In addition yielding stronger with respect other proposals for QED, this approach leads qubit-resonator...

Large-scale quantum information processors or communication networks will require reliable exchange of between spatially separated nodes. The links connecting these nodes can be established using traveling photons that need to absorbed at the receiving node with high efficiency. This is achievable by shaping temporal profile and absorbing them receiver time reversing emission process. Here, we demonstrate a scheme for creating shaped microwave superconducting transmon-type three-level system...

Steering a quantum harmonic oscillator state along cyclic trajectories leads to path-dependent geometric phase. Here we describe its experimental observation in an electronic oscillator. We use superconducting qubit as nonlinear probe of the phase, which is otherwise unobservable due linearity show that phase is, for variety paths, proportional area enclosed quadrature plane. At transition nonadiabatic regime, study corrections and dephasing caused by qubit-resonator entanglement. In...

Geometric phases, which accompany the evolution of a quantum system and depend only on its trajectory in state space, are commonly studied two-level systems.

We measure contribution second excited to find good agreement with theory treating higher energy levels perturbatively. By changing time, confirm independence time explore validity...

A quantum system interacting with its environment is subject to dephasing which ultimately destroys the information it holds. Using a superconducting qubit, we experimentally show that this has both dynamic and geometric origins. It found dephasing, present even in adiabatic limit when no phase acquired, can either reduce or restore coherence depending on orientation of path qubit traces out projective Hilbert space. accompanies evolution any space subjected noise.
