Nonlinear Quantum Optics Group




Our group explores how we can create strong optical nonlinearity in a medium at light levels of individual photons. Such a quantum nonlinear medium mediates an effective interaction between single photons and thus opens the possibility of manipulating light at its most fundamental level. Our goal is to realize a system that enables full control over the quantum state of few photon light pulses.
