Journal ArticleDOI
Ultrastrong coupling of a single artificial atom to an electromagnetic continuum in the nonperturbative regime
P. Forn-Díaz,Juan José García-Ripoll,Borja Peropadre,Jean-Luc Orgiazzi,M. A. Yurtalan,Ron Belyansky,Christopher Wilson,Adrian Lupascu +7 more
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
Quantum non-demolition measurement of a superconducting two-level system
Adrian Lupascu,Adrian Lupascu,Shiro Saito,Shiro Saito,T. Picot,P. C. de Groot,C.J.P.M. Harmans,J. E. Mooij +7 more
TL;DR: In this article, the hysteretic behavior of a coupled nonlinear resonator has been investigated in the context of quantum non-demolition (QND) measurements on a superconducting flux qubit.
Journal ArticleDOI
High-Contrast Dispersive Readout of a Superconducting Flux Qubit Using a Nonlinear Resonator
TL;DR: High-contrast state detection of a superconducting flux qubit is demonstrated by probing the microwave transmission of a nonlinear resonator, based on a SQUID.
Journal ArticleDOI
Observation of Floquet States in a Strongly Driven Artificial Atom.
TL;DR: The role of pulse shaping in the dynamics, as determined by nonadiabatic transitions between Floquet states, is observed, and subnanosecond single-qubit operations are implemented.
Journal ArticleDOI
Nondestructive readout for a superconducting flux qubit
TL;DR: The intrinsic flux detection efficiency and backaction are suitable for a fast and nondestructive determination of the quantum state of the qubit, as needed for readout of multiple qubits in a quantum computer.
