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

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 …

Quantum technology is an emergent and potentially disruptive discipline, with the ability to
affect many human activities. Quantum technologies are dual-use technologies, and as such …

Quantum sensing, built upon fundamental quantum phenomena like entanglement and
squeezing, is revolutionizing precision and sensitivity across diverse domains, including …

The contrast of an image can be degraded by the presence of background light and sensor
noise. To overcome this degradation, quantum illumination protocols have been theorized …

We built and evaluated a prototype quantum radar, which we call a quantum two-mode
squeezing (QTMS) radar, in the laboratory. It operates solely at microwave frequencies; …

Quantum illumination (QI) and quantum radar have emerged as potentially groundbreaking
technologies, leveraging the principles of quantum mechanics to revolutionise the field of …

The field of propagating quantum microwaves is a relatively new area of research that is
receiving increased attention due to its promising technological applications, both in …
