Ultrastrong coupling regimes of light-matter interaction

P. Forn-Díaz, +4 more
- 07 Jun 2019 - 
TL;DR: The ultrastrong coupling (USC) regime is established when the light-matter interaction energy is a comparable fraction of the bare frequencies of the uncoupled systems as discussed by the authors.
Journal ArticleDOI

Observation of the Bloch-Siegert shift in a qubit-oscillator system in the ultrastrong coupling regime

P. Forn-Díaz, +8 more
- 30 Nov 2010 - 
TL;DR: The dispersive energy-level shift of an LC resonator magnetically coupled to a superconducting qubit is measured, which clearly shows that the system operates in the ultrastrong coupling regime.
Journal ArticleDOI

Ultrastrong coupling of a single artificial atom to an electromagnetic continuum in the nonperturbative regime

P. Forn-Díaz, +7 more
- 01 Jan 2017 - 
TL;DR: In this paper, a superconducting artificial atom coupled to a 1D waveguide has been shown to reach the nonperturbative regime of ultrastrong coupling, where spontaneous emission rate of the atom exceeds its transition frequency.
Journal ArticleDOI

Switchable ultrastrong coupling in circuit QED

Borja Peropadre, +4 more
- 06 Jul 2010 - 
TL;DR: Different designs of switchable coupling between a superconducting flux qubit and a microwave transmission line based on two or more loops of Josephson junctions which are directly connected to a closed (cavity) or open transmission line are proposed.
Journal ArticleDOI

Strong coupling of a quantum oscillator to a flux qubit at its symmetry point.

Arkady Fedorov, +6 more
- 05 Aug 2010 - 
TL;DR: A flux qubit biased at its symmetry point shows a minimum in the energy splitting (the gap), providing protection against flux noise, and full spectroscopy of the qubit-oscillator system and vacuum Rabi oscillations are shown.
