Physical Review A

Density operator with coherent, number, and squeezed states

Abstract

A new approach to developing the series expansion of the density operator of quantum optics is given, and the result is applied to finding the second-order polarization vector. Coherent, number, and squeezed states are each investigated and the results compared.

New optical field operator expansion in number state representation

Yang Yang, Hong-Yi Fan

By virtue of the Weyl ordering method, we find a new formalism of optical field operator expansion in number state representation. Miscellaneous optical fields' (coherent state, squeezed field, Wigner operator, etc.) new expansions are therefore exhibited. Some new generating functions of special polynomials are derived herewith.

SECOND-ORDER CORRELATION FUNCTION FOR SUCCESSIVE SQUEEZED STATES

Vasile A. Popescu

By successive application of the squeeze operator, we obtain different quantum statistical properties for the squeezed number, the squeezed thermal, the squeezed coherent and the displaced squeezed thermal states. We compare our enhanced squeezing method with other procedures for superposition of two squeezed coherent states.

Expansion coefficients of a squeezed coherent state in the number state basis

Jiaxin Gong, P. K. Aravind

An analytic expression is obtained for the expansion coefficients of a single-mode squeezed coherent state in the number state (or Fock) basis. This is done by deriving a set of coupled recursion relations for the coefficients that are solved in closed form. The result coincides with that of Stoler and Yuen but the present method has the advantage (for neophytes) that it does not involve any sophisticated operator ordering techniques. Thus the present approach is suitable for inclusion in a course on quantum mechanics dealing with squeezed states.

Calculating Density Operator from Diagonal Coherent State Representation

Fan Hong-Yi, Huan Tu-Nan

By means of combining the coherent's properties with the normal product's properties we put forward to a formulation for obtaining density operators from Glauber-Suaaishan “P representation” and other non-diagonal representations directly in quantum optics.

Comparative analysis of properties for amplified coherent state and amplified squeezed vacuum

Yanbei Cheng, Shengguo Guan, Zujian Wang +1 more

Two “amplified” quantum states, that is, amplified coherent state (ACS) and amplified squeezed vacuum (ASV), are considered in this paper by applying operator [Formula: see text] on coherent state (CS) and squeezed vacuum (SV), respectively. Here [Formula: see text] [Formula: see text] denotes a amplification factor and [Formula: see text]) denote the creation (annihilation) operator. Along these two lines, we make a comparative analysis of properties for ACS and ASV. The considered properties include density matrix elements, Wigner function, mean photon number, second-order autocorrelation function, and quadrature squeezing. We derive analytical expressions and make numerical simulations for all the properties. The noteworthy results include: (1) the ACS has antibunching and squeezing characters; (2) the ASV will have the bunching and antibunching effect in small initial squeezing.
