Developing an inductive spectrometer for electron paramagnetic resonance detection and imaging at the micron scale using superconducting quantum circuits.

Electron paramagnetic resonance (EPR) is a powerful spectroscopy method which allows to identify paramagnetic species and quantify their interactions with their environment. Because of the weak spin-microwave coupling, conventional EPR spectroscopy has a low sensitivity which limits its use to samples of macroscopic size. Recent experiments demonstrated that superconducting quantum circuits have the potential to drastically enhance the spin detection sensitivity down to the detection of ~10 spins within 5 fL. However, these demonstrations have so far been done using well-known model spin systems and in restrictive conditions: very narrow spin and detector linewidths, extremely low microwave…
