TL;DR: This work studies a new type of interferometer in which the beam splitting and recombination elements are parametric amplifiers, and observes an improvement of 4.1±0.3 dB in signal-to-noise ratio.

TL;DR: In this article, the authors constructed an interferometer with parametric amplifiers as beam splitters, and they found that the fringe intensity depends quadratically on the intensity of the phase sensing field at high gain.

TL;DR: This work reports on a source that provides a method for generating quantum correlated beams that can be extended to a large number of modes by using multiple four-wave mixing processes in hot rubidium vapor and is immune to phase instabilities due to its phase insensitive nature, and has potential applications in the production of multiple quantum correlated images.

TL;DR: The authors use an OAM mode-matched parametric amplifier to demonstrate multiplexed all-optical quantum teleportation, also on OAM-mode superpositions, which demonstrates the teleportation of more than one optical mode with fidelity beating the classical limit and thus ensures the increase of information transmission capacity.

TL;DR: In this article, a scheme for three-level cascade atoms to entangle two optomechanical oscillators as well as two-mode fields was proposed, and it was shown that two movable mirrors and twomode fields can be entangled even for bad cavity limits.
