Quantum states of light are central to photonic quantum technologies, which makes their measurement very important. But quantum states are extremely fragile. Fortunately, a nonlinear-optical device known as the optical parametric amplifier comes to rescue when measurement over a fragile quantum state is needed. It protects the measurement against optical losses and imperfect detection, enables addressing several modes simultaneously, and can substitute homodyne detection with direct detection.
Coffee, tea and cake will be served at 1:45 pm.
