Optical amplifier-powered quantum optical amplification
John Jeffers
I show that an optical amplifier, when combined with photon subtraction, can be used for quantum state amplification, adding noise at a level below the standard minimum. The device…

Nondeterministic Amplifier for Two Photon Superpositions
John Jeffers
We examine heralded nondeterministic noiseless amplification based on the quantum scissors device, which has been shown to increase the one-photon amplitude of a state at the expen…
