Criticality-Enhanced Quantum Sensing with a Parametric Superconducting Resonator

Pasquale Scarlino, Fabrizio Minganti, Simone Frasca, Marco Scigliuzzo, Guillaume Beaulieu

Quantum metrology, a cornerstone of quantum technologies, exploits entanglement and superposition to achieve higher precision than classical protocols in parameter-estimation tasks. When combined with critical phenomena such as phase transitions, the diver ...

Three-wave-mixing quantum-limited kinetic inductance parametric amplifier operating at 6 T near 1 K

Camille René Charles Roy, Pasquale Scarlino, Simone Frasca, Guillaume Beaulieu

Parametric amplifiers play a crucial role in modern quantum technology by enabling the enhancement of weak signals with minimal added noise. Traditionally, Josephson junctions have been the primary choice for constructing parametric amplifiers. Nevertheles ...

Observation of first- and second-order dissipative phase transitions in a two-photon driven Kerr resonator

Vincenzo Savona, Pasquale Scarlino, Fabrizio Minganti, Simone Frasca, Guillaume Beaulieu

In open quantum systems, dissipative phase transitions (DPTs) emerge from the interplay between unitary evolution, drive, and dissipation. While second-order DPTs have been predominantly investigated theoretically, first-order DPTs have been observed in si ...
