Noiseless amplification of weak coherent fields without external energy
Mikko Partanen, Teppo Häyrynen, Jani Oksanen +1
According to the fundamental laws of quantum optics, noise is necessarily added to the system when one tries to clone or amplify a quantum state. However, it has recently been show…

Noiseless amplification of weak coherent fields exploiting energy fluctuations of the field
Mikko Partanen, Teppo Häyrynen, Jani Oksanen +1
Quantum optics dictates that amplification of a pure state by any linear deterministic amplifier always introduces noise in the signal and results in a mixed output state. However,…
