We introduce a new state called photon-added-and-subtracted two modes pair coherent
state (PAASTMPCS) by simultaneously adding and subtracting photons to the different …

Pair coherent states (PCSs) as a kind of two-mode non-Gaussian and nonclassical states
were introduced and studied. Some nonclassical characteristics of them such as two-mode …

After reviewing parity-measurement-based interferometry with twin Fock states, which allows
for supersensitivity (Heisenberg limited) and super-resolution, we consider interferometry …

In this paper, a new state called superposition of multiple-photon-added two-mode
squeezed vacuum state (SMPA-TMSVS) is introduced by adding the multiple photons to …

Quantum-optical catalysis is a quantum state engineering that can convert states (Gaussian
and/or non-Gaussian) into non-Gaussian states without changing the number of photons in …

Trio coherent states as a kind of three-mode entangled state were introduced and studied.
Some nonclassical characteristics of them such as higher-order antibunching, three-mode …

Realistic quantum systems are the main part of quantum information technology, which
causes the rapid destruction of crucial quantum properties. Therefore, the unavoidable …

We consider a continuous-variable Clauser-Horne Bell-type inequality to study nonlocality in
four-mode continuous-variable systems, which goes beyond two-photon states and can be …

In this paper, we study the nonclassical properties and find out the effect of photon addition
on these properties as well as the process of teleportation in the two-mode photon-added …

This review is intended for readers who want to have a quick understanding on the
theoretical underpinnings of coherent states and squeezed states which are conventionally …
