Abstract:
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.
