Quantum computing with superconducting circuits in the picosecond regime
Daoquan Zhu, Tuomas Jaako, Qiongyi He +1
We discuss the realization of a universal set of ultrafast single- and two-qubit operations with superconducting quantum circuits and investigate the most relevant physical and tec…
Super-correlated radiance in nonlinear photonic waveguides
Zhihai Wang, Tuomas Jaako, Peter Kirton +1
We study the collective decay of two-level emitters coupled to a nonlinear waveguide, for example, a nanophotonic lattice or a superconducting resonator array with strong photon-ph…
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…
Ultrastrong coupling circuit QED in the radio-frequency regime
T. Jaako, J. J. Garcia-Ripoll, P. Rabl
We study a circuit QED setup where multiple superconducting qubits are ultrastrongly coupled to a single radio-frequency resonator. In this extreme parameter regime of cavity QED t…
Breakdown of gauge invariance in ultrastrong-coupling cavity QED
Daniele De Bernardis, Philipp Pilar, Tuomas Jaako +2
We revisit the derivation of Rabi- and Dicke-type models, which are commonly used for the study of quantum light-matter interactions in cavity and circuit QED. We demonstrate that…
Cavity quantum electrodynamics in the non-perturbative regime
Daniele De Bernardis, Tuomas Jaako, Peter Rabl
We study a generic cavity-QED system where a set of (artificial) two-level dipoles is coupled to the electric field of a single-mode LC resonator. This setup is used to derive a mi…
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…
