Cavity magnonics deals with the interaction of magnons—elementary excitations in
magnetic materials—and confined electromagnetic fields. We introduce the basic physics …

Quantum-mechanical effects at the macroscopic level were first explored in Josephson-
junction-based superconducting circuits in the 1980s. In recent decades, the emergence of …

The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

Full manipulation of a quantum system requires controlled evolution generated by nonlinear
interactions, which is coherent when the rate of nonlinearity is large compared with the rate …

The accuracy of logical operations on quantum bits (qubits) must be improved for quantum
computers to outperform classical ones in useful tasks. One method to achieve this is …

We present a comprehensive architectural analysis for a proposed fault-tolerant quantum
computer based on cat codes concatenated with outer quantum error-correcting codes. For …

Engineered quantum systems enabling novel capabilities for computation and sensing have
blossomed in the last decade. Architectures benefiting from combining complementary …

In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

Phonons, and in particular surface acoustic wave phonons, have been proposed as a
means to coherently couple distant solid-state quantum systems. Individual phonons in a …

Fast, high-fidelity operations between microwave resonators are an important tool for
bosonic quantum computation and simulation with superconducting circuits. An attractive …
