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 …

A review is given on the foundations and applications of non-Hermitian classical and
quantum physics. First, key theorems and central concepts in non-Hermitian linear algebra …

The aim of this review is to provide quantum engineers with an introductory guide to the
central concepts and challenges in the rapidly accelerating field of superconducting …

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

The field of cavity optomechanics is reviewed. This field explores the interaction between
electromagnetic radiation and nanomechanical or micromechanical motion. This review …

A central goal of any quantum technology consists in demonstrating an advantage in their
performance compared to the best possible classical implementation. A quantum radar …

When two physical systems share the quantum property of entanglement, measurements of
one system appear to determine the state of the other. This peculiar property is used in …

Research in quantum information processing has followed two different directions: the use of
discrete variables (qubits) and that of high-dimensional, continuous-variable Gaussian …

The ability to generate particles from the quantum vacuum is one of the most profound
consequences of Heisenberg's uncertainty principle. Although the significance of vacuum …

We present a scheme to entangle two microwave fields by using the nonlinear
magnetostrictive interaction in a ferrimagnet. The magnetostrictive interaction enables the …
