We review the main works in the field of nonlinear interferometers, which has been
develo** ever since the start of nonlinear optics and has seen growing interest in recent …

The fractional Fourier transform (FrFT), a fundamental operation in physics that corresponds
to a rotation of phase space by any angle, is also an indispensable tool employed in digital …

A new type of hybrid atom-light interferometer is demonstrated with atomic Raman
amplification processes replacing the beam splitting elements in a traditional interferometer …

We demonstrate an efficient cross-phase modulation (XPM) based on a closed-loop double-
Λ system. The property of the double-Λ medium can be controlled by changing the phases of …

We show that a set of optical memories can act as a configurable linear optical network
operating on frequency-multiplexed optical states. Our protocol is applicable to any quantum …

The gradient-echo memory (GEM) scheme has potential to be a suitable protocol for storage
and retrieval of optical quantum information. In this paper, we review the properties of the Λ …

A device being a pinnacle of development of an optical quantum memory should combine
the capabilities of storage, inter-communication, and processing of stored information. In …

The interference of photons in a lossy beam splitter (BS) exhibits anticoalescence, which is
surprising for bosons. Such a non-Hermitian system involving open quantum dynamics is of …

A number of techniques exist to use an ensemble of atoms as a quantum memory for light.
Many of these propose to use backward retrieval as a way to improve the storage and recall …

We propose a simple architecture based on multimode quantum memories for collective
readout of classical information keyed using a pair coherent states, exemplified by the well …
