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

During the last ten years, superconducting circuits have passed from being interesting
physical devices to becoming contenders for near-future useful and scalable quantum …

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 …

Quantum illumination uses entangled signal-idler photon pairs to boost the detection
efficiency of low-reflectivity objects in environments with bright thermal noise. Its advantage …

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 …

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

We present a scheme to entangle the vibrational phonon modes of two massive
ferromagnetic spheres in a dual-cavity magnomechanical system. In each cavity, a …

Squeezing of the electromagnetic vacuum is an essential metrological technique used to
reduce quantum noise in applications spanning gravitational wave detection, biological …

The recent launch of the Micius quantum-enabled satellite heralds a major step forward for
long-range quantum communication. Using single-photon discrete-variable quantum states …

Mechanical systems facilitate the development of a hybrid quantum technology comprising
electrical, optical, atomic and acoustic degrees of freedom, and entanglement is essential to …
