We are advancing the frontier of quantum measurement science by exploring the unique properties of entangled photons interacting with fluorescent proteins and other fluorophores used in cellular imaging. For example, time-energy entanglement can significantly enhance nonlinear light-matter interactions. Entangled two-photon absorption follows linear rather than the classical quadratic intensity dependence and can be observed at much lower photon fluxes than two-photon absorption in conventional multiphoton microscopy.
