A high-fidelity noiseless amplifier for quantum light states
Original language description
Noise is the price to pay when trying to clone or amplify arbitrary quantum states. However, the quantum noise associated with linear phase-insensitive amplifiers can be avoided by relaxing the requirement of a deterministic operation. Here we present the experimental realization of a novel concept of a probabilistic noiseless linear amplifier that is able to amplify coherent states at the highest levels of effective gain and final state fidelity ever reached. Based on a sequence of photon addition andsubtraction, this high-fidelity amplification scheme is likely to become an essential tool for applications of quantum communication and metrology.
