Scientific activity

The PHASME team at LPEM (ESPCI Paris) conducts research on superconductivity and superconducting devices, with a particular focus on quantum technologies. Its activities cover both the study of the fundamental properties of superconductors—in particular low-dimensional, strongly correlated, and unconventional systems—and the design and characterization of superconducting circuits operating at microwave frequencies.

We use experimental techniques such as microwave spectroscopy, transport measurements, and tunneling spectroscopy to probe the electrodynamic response, superfluid stiffness, and dynamics of quasiparticles. Based on this microscopic understanding, the group studies and develops superconducting devices such as resonators, spin-photon hybrid systems, and detectors, targeting applications in quantum information processing, quantum sensors, and photon detection.

At the frontier between condensed matter physics and quantum electrodynamics in circuits, PHASME contributes to the understanding of superconducting phenomena and the development of superconducting quantum devices.
