Abstract

By introducing the Hermite-polynomial-operator Hn(X), where X is the coordinate operator (or the quadrature operator in quantum optics theory), and combining the technique of integration within an ordered product of operators, we derive some new operator identities about quantum squeezing, which are useful for studying the squeezed number state.

New Applications of Two-mode Hermite Polynomials in Quantum Optics Theory

Fan Hong‐Yi

We emphasize the importance of two-mode Hermite poly-nomials in quantum optics theory,we consider it as the prominent function in studying the entangled state of continuum variables and two-mode squeezed state,and that possesses a clear physical meaning.By virtue of the two-mode Hermite polynomials and combining operators' integration technique within normal and antinormal orderings,we derive some new operator identities and mutual invertible integration transformation,and prove that squeezed two-mode number state is just the two-mode Hermite polynomial excited squeezed two-mode vacuum state.

New generating function formulae of even- and odd-Hermite polynomials obtained and applied in the context of quantum optics

范洪义, 展德会

By combining the operator Hermite polynomial method and the technique of integration within an ordered product of operators, for the first time we derive the generating function of even- and odd-Hermite polynomials which will be useful in constructing new optical field states. We then show that the squeezed state and photon-added squeezed state can be expressed by even- and odd-Hermite polynomials.

New operator identities with regard to the two-variable Hermite polynomial by virtue of entangled state representation

Hong‐Chun Yuan, Heng-Mei Li, Xuefen Xu

By virtue of the entangled state representation we concisely derive some new operator identities with regard to the two-variable Hermite polynomial (TVHP). By them and the technique of integration within an ordered product (IWOP) of operators we further derive new generating function formulas of the TVHP. They are useful in quantum optical theoretical calculations. It is seen from this work that by combining the IWOP technique and quantum mechanical representations one can derive some new integration formulas even without really performing the integration.

Deriving operator identities by two-mode coherent-entangled state representation

Nanrun Zhou, Gong Li-Hua, Jia Fang +1 more

On the basis of the new introduced two-mode coherent entangled state representation and the technique of integration within an ordered product of operators, we derived some operator identities of the operator functions about the quadrature of two-mode optical field, such as （X1+X2）/21/2 and （μX1+νX2）/λ, which should be helpful to further studying the high order squeezing properties of optical field and to constructing some generalized-squeezed states.

New useful special function in quantum optics theory

Feng Chen, Hong-Yi Fan

By virtue of the operator Hermite polynomial method [Fan H Y and Zhan D H 2014 Chin. Phys. B 23 060301] we find a new special function which is useful in quantum optics theory, whose expansion involves both power-series and Hermite polynomials, i.e., By virtue of the operator Hermite polynomial method and the technique of integration within ordered product of operators (IWOP) we derive its generating function. The circumstance in which this new special function appears and is applicable is considered.
