Quantum sensors based on solid-state defects, in particular nitrogen-vacancy (NV) centers
in diamond, enable precise measurement of magnetic fields, temperature, rotation, and …

A fundamental result of quantum mechanics is that the fluctuations of a bosonic field are
given by its temperature T. An electromagnetic mode with frequency ω in the microwave …

The majority of sources of coherent optical radiation rely on laser oscillators driven by
population inversion. Despite their technological importance in communications, medicine …

Enhancing the spontaneous and stimulated emission rates of magnetic quantum emitters
through Purcell effect is essential for designing high-performance quantum devices based …

We present a novel design of loop-gap resonator, the loop-zag resonator, for sub-X-band
electron-spin resonance spectroscopy. The loop-zag design can achieve improved coupling …

The analysis of cylindrical resonators is part of standard physics curricula but, unlike for their
rectangular counterpart, their mode structure is hardly ever visualized. The aim of this work …

Strong light-matter interaction enabled many modern technologies such as precision
metrology, light sources, optical communication and spectroscopy. Normally, the coupling …

Robust, high-fidelity readout is central to quantum device performance. Overcoming poor
readout is therefore an increasingly urgent challenge for devices based on solid-state spin …
