Toward the realization of monocycle entangled photons for novel nonlinear quantum optics

Research Project Outline

Photons entangled on timescales of one period of the light field oscillation represent the ultimate limit of quantum correlations in time and frequency. In this project, we aim to generate such monocycle entangled photons by developing sophisticated quasi-phase-matched nonlinear optical devices. This optimization of the spectral and temporal features of light enables us to explore new aspects of optical nonlinearities at the quantum level, e.g. enhanced two photon absorption and related non-linear two photon interactions, or ultra-sensitive measurements in quantum metrology.
