Electron paramagnetic resonance (EPR) spectroscopy characterizes the magnetic
properties of paramagnetic materials at the atomic and molecular levels. Resonators are an …

The use of superconducting microresonators together with quantum-limited Josephson
parametric amplifiers has enhanced the sensitivity of pulsed electron spin resonance (ESR) …

Hybrid architectures combining complementary quantum systems will be largely used in
quantum technologies and the integration of different components is one of the key issues …

Parasitic two-level-system (TLS) defects are one of the major factors limiting the coherence
times of superconducting qubits. Although there has been significant progress in …

Impurity spins in crystal matrices are promising components in quantum technologies,
particularly if they can maintain their spin properties when close to surfaces and material …

We report the development and test of planar microwave Inverse Anapole Resonators
(IARs) made of superconducting Yttrium Barium Copper Oxide (YBCO) for electron spin …

As in conventional computing, memories for quantum information benefit from high storage
density and, crucially, random access, or the ability to read from or write to an arbitrarily …

Electron spins are amongst the most coherent solid-state systems known. However, to be
used in devices for quantum sensing and information processing applications, they must …

Inspired by the success of NMR cryoprobes, we recently reported a leap in X-band EPR
sensitivity by equipping an ordinary EPR probehead with a cryogenic low-noise microwave …

Following the success of cryogenic EPR signal preamplification at X-band, we present a Q-
band EPR cryoprobe compatible with a standard EPR resonator. The probehead is …
