Current definitions of both squeezing operator and squeezed vacuum state are critically examined on the grounds of consistency with the underlying su(1,1) algebraic structure. Accordingly, the generalized coherent states for su(1,1) in its Schwinger two-photon realization are proposed as squeezed states. The physical implication of this assumption is that two additional degrees of freedom become available for the control of quantum optical systems. The resulting physical predictions are…

On the derivation of exact eigenstates of the generalized squeezing operator

We construct the states that are invariant under the action of the generalized squeezing operator exp(za†k−z*ak) for arbitrary positive integer k. The states are given explicitly in the number…

Efficient algebraic solution for a time-dependent quantum harmonic oscillator

Using operator ordering techniques based on Baker-Campbell-Hausdorff (BCH) relations of the su(1,1) Lie algebra and a time-splitting approach, we present an alternative method of solving the dynamics…

Squeezed states of light and their applications in laser interferometers

REVIEW ARTICLE: `Nonclassical' states in quantum optics: a `squeezed' review of the first 75 years

Seventy five years ago, three remarkable papers by Schr¨ odinger, Kennard and Darwin were published. They were devoted to the evolution of Gaussian wave packets for an oscillator, a free particle and…

Quantum light in coupled interferometers for quantum gravity tests.

It is demonstrated that the use of quantum correlated light beams in coupled interferometers leads to substantial advantages with respect to classical light, up to a noise-free scenario for the ideal lossless case.

Optimal quantum estimation of loss in bosonic channels.

The ultimate quantum bound is derived with precision and no improvement may be obtained by having access to the environmental degrees of freedom, a result that represents a qualitative improvement over the shot-noise limit.

Phase estimation with squeezed single photons

Abstract We address the performance of an interferometric setup in which a squeezed single photon interferes at a beam splitter with a coherent state. Our analysis in based on both the quantum Fisher…

Squeezed light for advanced gravitational wave detectors and beyond.

The limitations of current squeezed vacuum sources are discussed in relation to the requirements imposed by future gravitational wave detectors, and a design for squeezed light injection which overcomes these limitations is shown.
