Coupling schemes Sample Clauses

Coupling schemes a) Charge-like qubit capacitively coupled to a high-impedance waveguide. b) Flux qubit inductively coupled to a resonator using a shared superinductor (similar to [Pop2014, Grunhaupt&Spiecker2018]). These two types of interactions cover all circuits described in the work packages. The scheme in Fig. 3a will be used for quantum simulations in an open setting where the qubit scatters incoming photons, emulating impurity scattering in a solid. The qubit-waveguide USC enabled by the superinductor will allow the exploration of physics related to photon localization equivalent to a Kondo model for microwave photons [Snyman2015] and particle production effects [Geerahert2018]. The scheme in Fig. 3b will instead be used to characterize the quantum coherence of the whole qubit-resonator system in the USC regime for the first time, following expectations from the literature [Xxxxx0000x, Nataf2011]. The high quality superinductor will preserve intrinsic qubit coherence. The same device will then be used to explore physics of the USC regime thoroughly. These include the simulation of superradiant/subradiant physics [DeBernardis2018], and qubit- resonator vacuum-induced STIRAP processes [Xxxxx0000x, Xxxxx0000x].
