Squeezed states, special kinds of entangled states, are known as a useful resource for quantum metrology. In interferometric sensors, they allow us to overcome the ‘classical’ projection noise limit stemming from the independent nature of the individual photons or atoms within the interferometer. Motivated by the potential impact on metrology as well as by fundamental questions in the context of entanglement, a lot of theoretical and experimental effort has been made to study squeezed states… 
Quantum metrology from a quantum information science perspective
We summarize important recent advances in quantum metrology, in connection to experiments in cold gases, trapped cold atoms and photons. First we review simple metrological setups, such as quantum
Quantum nondemolition measurement based generation of entangled states in two Bose–Einstein condensates
We theoretically study a scheme for generating entanglement between two Bose–Einstein condensates (BECs). The scheme involves placing two BECs in the path of a Mach–Zehnder interferometer, where the

Split spin-squeezed Bose–Einstein condensates
We investigate and model the behaviour of split spin-squeezed Bose-Einstein condensates (BECs) system. In such a system, a spin-polarized BEC is first squeezed using a $ (S^z)^2 $ interaction, then
Generating Stable Spin Squeezing by Squeezed-Reservoir Engineering.
This work proposes a scheme to generate stable SS resorting to neither the spin-spin coupling nor the coherent driving on the TLSs, and exhibits the advantages over previous ones in the scaling relation of the SS parameter with the number of the TLS's.
Molecular interferometers: effects of Pauli principle on entangled-enhanced precision measurements
. Feshbach molecules forming a Bose-Einstein condensate (BEC) behave as non-ideal bosonic particles due to their underlying fermionic structure. We study the observable consequences of the fermion


Squeezing and entanglement in a Bose–Einstein condensate
Spin squeezed states suitable for atomic interferometry are demonstrated by splitting a condensate into a few parts using a lattice potential by implying entanglement between the particles.
Spin Squeezing and Non-linear Atom Interferometry with Bose-Einstein Condensates
Interferometry is the most precise measurement technique known today. It is based on interference and therefore on the wave-like nature of the resources – photons or atoms – in the interferometer. As
Mesoscopic atomic entanglement for precision measurements beyond the standard quantum limit
There is an optimal degree of decoherence induced by the quantum measurement which maximizes the generated entanglement, and a 2-color QND scheme used in this paper is shown to have a number of advantages for entanglements generation as compared with a single- color QND measurement.

Atom-chip-based generation of entanglement for quantum metrology
The experimental generation of multi-particle entanglement on an atom chip is reported by controlling elastic collisional interactions with a state-dependent potential to generate spin-squeezed states of a two-component Bose–Einstein condensate; such states are a useful resource for quantum metrology.
