• Abstract: Time-reversal symmetry breaking (TRSB) has been central to detecting exotic phases of matter, often linked to complex superconducting order parameters or unique magnetic phenomena. Here, we leverage circuit electrodynamics capabilities of superconducting devices to propose a novel scheme based on a multimode superconducting ring resonator for sensitive probing of TRSB in quantum materials. Our device enables strong nonlinear interactions between the modes and we show that these interactions can lead to highly symmetric configurations which are sensitive to TRSB. Using a driven-dissipative model, we explore the nonlinear dynamics of a two-mode superconducting circuit with self- and cross-Kerr nonlinearities under conditions near the bifurcation threshold. When TRSB coupling is introduced, the critical behavior of the system serves as a highly sensitive detection method. Specifically, by mapping out the optimal parameter regimes, we show that even when the photon occupation numbers are subjected to different initial conditions, they can be driven into a symmetric configuration which can be broken even with weak TRSB. Our findings highlight the utility of superconducting microwave resonators other than quantum information processing as a tool for probing exotic states of matter.

  This work explores the possibility of creating and controlling unconventional nonlinearities by periodic driving. By means of a parent quantum many-body description, we demonstrate that such driven systems are well captured by an effective NLSE. We analyze these intriguing properties both in the weakly-interacting (mean-field) regime, captured by the effective NLSE, and in the strongly-correlated quantum regime.

  Fast, high-fidelity operations between microwave resonators are an important tool for bosonic quantum computation and simulation. An attractive approach is to couple these resonators via a nonlinear converter and actuate parametric processes with RF drives. We show that in addition to a careful management of drive frequencies and the spectrum of environmental noise, leveraging the inbuilt symmetries of the converter Hamiltonian can suppress unwanted nonlinear interactions. We characterize this beamsplitter in the cavities' joint single-photon subspace, and show that we can detect and post-select photon loss events to achieve a beamsplitter gate

  We show that the simplest set-up of two qubits, harmonically trapped over an optical waveguide, enables the ultrastrong coupling regime of the quantum optomechanical interaction. The combination of the inherent open nature of the system and the strong optomechanical coupling leads to emerging parity-time (PT) symmetry. The $mathcalPT$ phase transition drives long-living subradiant states, observable in the state-of-the-art waveguide QED setups.
