Electron spin resonance spectroscopy is the method of choice for characterizing
paramagnetic impurities, with applications ranging from chemistry to quantum computing …

When strongly pumped at twice their resonant frequency, nonlinear resonators develop a
high-amplitude intracavity field, a phenomenon known as parametric self-oscillations. The …

Single-photon detection played an important role in the development of quantum optics. Its
implementation in the microwave domain is challenging because the photon energy is five …

By strongly driving a transmon-resonator system, the transmon qubit may eventually escape
from its cosine-shaped potential. This process is called transmon ionization (TI) and known …

We use an erbium doped CaWO 4 crystal as a resonant transducer between the RF and
optical domains at 12 GHz and 1532 nm respectively. We employ a RF resonator to …

Counting the microwave photons emitted by an ensemble of electron spins when they relax
radiatively has recently been introduced as a sensitive new method for electron …

Clock transitions (CTs) in spin systems, which occur at avoided level crossings, enhance
quantum coherence lifetimes T $ _2 $ because the transition becomes immune to the …

Experimental search of galactic axions requires detection of single photons in the
microwave range. We work on a novel approach to detect single microwave photons based …

Electron Spin Resonance (ESR) spectroscopy is a characterization method applicable to a
wide variety of spin systems. This method, usually based on the Inductive Detection (ID) of …
