Transmon-qubit readout using in-situ bifurcation amplification in the mesoscopic regime
R. Dassonneville, T. Ramos, V. Milchakov +8
We demonstrate a transmon qubit readout based on the nonlinear response to a drive of polaritonic meters in-situ coupled to the qubit. Inside a 3D readout cavity, we place a transm…
Quantum control of tunable-coupling transmons using dynamical invariants of motion
Hilario Espinós, Iván Panadero, Juan José García-Ripoll +1
We analyse the implementation of a fast nonadiabatic CZ gate between two transmon qubits with tuneable coupling. The gate control method is based on a theory of dynamical invariant…
Quantum Simulation of Non-perturbative Cavity QED with Trapped Ions
Tuomas Jaako, Juan José Garcia-Ripoll, Peter Rabl
We discuss the simulation of non-perturbative cavity-QED effects using systems of trapped ions. Specifically, we address the implementation of extended Dicke models with both colle…
Fast high fidelity quantum non-demolition qubit readout via a non-perturbative cross-Kerr coupling
R. Dassonneville, T. Ramos, V. Milchakov +12
Qubit readout is an indispensable element of any quantum information processor. In this work, we experimentally demonstrate a non-perturbative cross-Kerr coupling between a transmo…
Quantum probe of an on-chip broadband interferometer for quantum microwave photonics
P. Eder, T. Ramos, J. Goetz +11
Quantum microwave photonics aims at generating, routing, and manipulating propagating quantum microwave fields in the spirit of optical photonics. To this end, the strong nonlinear…
Ultrastrong coupling phenomena beyond the Dicke model
Tuomas Jaako, Ze-Liang Xiang, Juan José Garcia-Ripoll +1
We study effective light-matter interactions in a circuit QED system consisting of a single resonator, which is coupled symmetrically to multiple superconducting qubits. Start…
Quantum Simulation of the Ultrastrong Coupling Dynamics in Circuit QED
D. Ballester, G. Romero, J. J. García-Ripoll +2
We propose a method to get experimental access to the physics of the ultrastrong (USC) and deep strong (DSC) coupling regimes of light-matter interaction through the quantum simula…
Deep Strong Coupling Regime of the Jaynes-Cummings model
J. Casanova, G. Romero, I. Lizuain +2
We study the quantum dynamics of a two-level system interacting with a quantized harmonic oscillator in the deep strong coupling regime (DSC) of the Jaynes-Cummings model, that is,…
