A Real-time Instanton Approach to Quantum Activation
Chang-Woo Lee, Paul Brookes, Kee-Su Park +2
Driven-dissipative nonlinear systems exhibit rich critical behavior, related to bifurcation, bistability and switching, which underlie key phenomena in areas ranging from physics,…
Protection of quantum information in a chain of Josephson junctions
Paul Brookes, Tikai Chang, Marzena Szymanska +3
Symmetry considerations are key towards our understanding of the fundamental laws of Nature. The presence of a symmetry implies that a physical system is invariant under specific t…
Driving-induced resonance narrowing in a strongly coupled cavity-qubit system
Eyal Buks, Paul Brookes, Eran Ginossar +4
We study a system consisting of a superconducting flux qubit strongly coupled to a microwave cavity. Externally applied qubit driving is employed in order to manipulate the spectru…
Critical slowing down in the bistable regime of circuit quantum electrodynamics
P. Brookes, G. Tancredi, A. D. Patterson +5
We investigate the dynamics of the bistable regime of the generalized Jaynes-Cummings Hamiltonian (GJC), realised by a circuit quantum electrodynamics (cQED) system consisting of a…
