Entanglement enhancement with cascaded nondegenerate optical parametric amplifier

Entanglement enhancement with cascaded nondegenerate optical parametric amplifier

We experimentally demonstrate the cascaded entanglement enhancement of continuous variables. The quantum correlations are successively enhanced by two nondegenerate optical parametric amplifiers from -5.3 dB to -8.1 dB below quantum noise limit.
