Quantum Coherent Absorption of Squeezed Light [PDF]
Optica, 2019 We investigate coherent perfect absorption (CPA) in quantum optics, in particular when pairs of squeezed coherent states of light are superposed on an absorbing beam splitter.

In chapter 12 we introduced the Bose operators b and b†. In this chapter we study the spectrum of b. This leads to the so-called coherent states (Louisell [37]). We adopt the Dirac notation. Coherent states are applied to a wide variety of physical problems (Klauder and Skagerstam [32], Kowalski and Steeb [33]).

Double squeezing in generalized q-coherent states
Journal of Physics A: Mathematical and General, 1994Summary: Using a generalization of the \(q\)-commutation relations, we develop a formalism in which we define generalized \(q\)-bosonic operators. This formalism includes both types of the usual \(q\)-deformed bosons as special cases. The coherent states of these operators show interesting and novel noise reduction properties including simultaneous ...

Abstract Squeezed state of light has drawn an enormous attention in information processing and digital communication since it has broken the quantum limit of noise. Here we have analytically investigated the interactions among coherent and vacuum squeezed states of light, interaction among coherent vacuum and squeezed states of light, and that ...

Holonomic quantum computation with squeezed coherent states
Proceedings of the 41st IEEE Conference on Decision and Control, 2002., 2003Control theoretic aspects of holonomic quantum computation are presented. A generating set of holonomic transformations is constructed from the product bundle arising from the two-qubit system of holonomic quantum computation with squeezed coherent states.

Thermal Coherent States and Thermal Squeezed States
Journal of Modern Optics, 1991Abstract Various definitions of thermal coherent states and thermal squeezed states are compared and interrelated. Different ordering of squeezing, displacement and thermalizing operators is discussed in order to establish a relation between all definitions.

Gaussian coherent state expansion of the squeezed states
Optics Communications, 1990Abstract It is shown that gaussian coherent state expansions describe squeezed states. The non-analytic gaussian expansion allows to reduce the dimensionality of the representation. Using this very convenient representation we calculated the quantities 〈 a †j a k 〉, which immediately give the mean value of any normally ordered operator ...

Generation of Superpositions of Squeezed Coherent States
Chinese Physics Letters, 1997A scheme to prepare superpositions of squeezed coherent states is presented. It involves an appropriately prepared atom crossing a high-Q cavity initially filled with a squeezed coherent field. After the nonresonant interaction with the cavity field the detection of the atomic state leaves the cavity field in a superposition of two squeezed coherent ...
