Abstract summary: We propose to couple the flux degree of freedom of one mode with the charge degree of freedom of a second mode in a hybrid superconducting-semiconducting architecture. Nonreciprocity can arise in this architecture in the presence of external static magnetic fields alone.

Abstract: We propose to couple the flux degree of freedom of one mode with the charge degree of freedom of a second mode in a hybrid superconducting-semiconducting architecture. Nonreciprocity can arise in this architecture in the presence of external static magnetic fields alone. We leverage this property to engineer a passive on-chip gyrator, the fundamental two-port nonreciprocal device which can be used to build other nonreciprocal devices such as circulators. We analytically and numerically investigate how the nonlinearity of the interaction, circuit disorder and parasitic couplings affect the scattering response of the gyrator.

Efficient decoupling of a non-linear qubit mode from its environment [0.9533143628888118]
We make use of the design flexibility of superconducting quantum circuits to form a multi-mode element with symmetry-protected modes. The proposed circuit consists of three superconducting islands coupled to a central island via Josephson junctions. We show that the coherence of the qubit is not limited by photon-induced dephasing when detuning the mediator mode from the readout resonator.

We provide a systematic method for constructing effective dispersive Lindblad master equations to describe weakly anharmonic superconducting circuits coupled by a generic dissipationless nonreciprocal linear system. Results can be used for the design of complex superconducting quantum processors with nontrivial routing of quantum information, as well as quantum simulators of condensed matter systems.

Superconducting coupler with exponentially large on-off ratio [68.8204255655161]
Tunable two-qubit couplers offer an avenue to mitigate errors in multiqubit superconducting quantum processors. Most couplers operate in a narrow frequency band and target specific couplings, such as the spurious $ZZ$ interaction. We introduce a superconducting coupler that alleviates these limitations by suppressing all two-qubit interactions with an exponentially large on-off ratio.

We demonstrate a low-loss waveguide circulator constructed with single-crystalline yttrium iron garnet (YIG) in a 3D cavity.

We develop a systematic procedure to quantise canonically Hamiltonians of light-matter models of transmission lines.

Hardware-Encoding Grid States in a Non-Reciprocal Superconducting Circuit [62.997667081978825]
We present a circuit design composed of a non-reciprocal device and Josephson junctions whose ground space is doubly degenerate and the ground states are approximate codewords of the Gottesman-Kitaev-Preskill (GKP) code. We find that the circuit is naturally protected against the common noise channels in superconducting circuits, such as charge and flux noise, implying that it can be used for passive quantum error correction.
