Squeezed states in direct and coherent detection
Optical and Quantum Electronics, 1992With reference to squeezed states, we analyse the noise performances of the basic detection schemes in fibre telecommunications and interferometry. We have developed a semiclassical approach that allows us to translate the quantum mechanical formalism into synthetic expressions and rules only involving directly measurable physical quantities.

Coherent states and squeezed light
2006Abstract In the preceding two chapters we have explored the consequences of quantizing the energy of a light beam in terms of the number of photons. This enabled us to classify light according to either the photon statistics or the second-order correlation function.

Coherent and squeezed states in phase space
Il Nuovo Cimento B Series 11, 1990In the present paper we study the coherent and the squeezed states in phase space. From the wave functions of the coherent and the squeezed states we calculate their corresponding Wigner distribution functions. Especially the calculation of the corresponding Wigner functions for the above states permits the determination of the mean values of position ...

Non-classicality and coherence of squeezed states
Physica A: Statistical Mechanics and its Applications, 2004Abstract After having set up a concise frame for pure and mixed all-order coherent states, we let them undergo a rather general squeezing transformation. These squeezed states are always non-classical, but some—apparently experimentally preparable—of them are still second-order coherent.

Coherent Phase State and Squeezed Phase State
1990Because of its importance for achieving the ultimate quantum limits on phase measurement,1,2 we have been investigating the properties of the Susskind-Glogower (SG) phase operator;3 for a single mode of the radiation field whose annihilation operator is â, the SG phase operator is $$\widehat {{e^{i\phi }}} \equiv {\left( {\hat a{{\hat a}^\dag ...

Eigenvalue equation of squeezed coherent states and time evolution of squeezed states
Journal of Physics A: Mathematical and General, 2002Summary: We define the eigenvalue equation of the squeezed coherent state using recently introduced inverse annihilation and creation operators. The salient feature of the eigenvalue equation of the squeezed coherent state is that it consistently yields the eigenvalue equation of the squeezed vacuum when the coherent amplitude is reduced to zero.

Coherent and squeezed states in quantum optics
Il Nuovo Cimento B Series 11, 1988In the present paper we produce several interesting properties of the Yuen operators and demonstrate that the squeeze operator is proportional to the well-known multiplication operator. By the help of the multiplication operator we obtain exactly the squeezed states in theq-representation which are the minimal uncertainty states.

GENERALIZED SUPERPOSITIONS OF SQUEEZED COHERENT STATES
Modern Physics Letters B, 2001The superpositions of a pair of squeezed coherent states (SCS) with different squeezing parameters are defined. The characteristic function (CF) for the generalized superpositions of SCSs is given. Photon number distribution for these states is considered. The Q-function for the generalized superposition of SCSs is investigated.
