Defining and controllably manipulating quantum states in a material presents both huge challenges and fantastic opportunities. We work at the interface of quantum optics, condensed-matter physics, and materials science to pursue this goal by creating novel quantum photonic devices. Read more.

Quantum dots

Semiconductor quantum dots are the most mature solid-state single-photon emitters. We use the best InAs/GaAs quantum dots to improve even more their coherence properties using specific excitation schemes and use them for quantum optics experiments.

2D materials

Different types of atomically-thin materials like WSe2, MoS2 and others have been found to exhibit quantum emitters due to defects and strain. We study these emitters and create novel heterostructures with these materials very easy to position and manipulate.

Spins in wide-bandgap semiconductors

We investigate electronic and nuclear spins associated to point defects in wide-bandgap semiconductors, such as diamond and silicon carbide with the goal to build quantum devices for sensing and communication.
