In my research I focus on control and detection of electron spins using the toolbox of superconducting quantum circuits.

Electron-spin detection in the microwave domain is usually performed through homodyne detection, a technique that allows to extract the coherent part of the field emitted by an ensemble of spins, disregarding all the interesting information contained in the incoherent part.

I am developing a novel spin-detection scheme based on a single microwave-photon counter which uses four wave mixing to directly trap the photons emitted by spins into a qubit excitation. This new technique will strongly increase detection sensitivity expecially

for low number of spins, moreover it will allow to measure both the coherent and incoherent emitted fields. The prospect are reaching single spin detection with microwave photons and studying noise from spontaneous emission of electron spins.
