Entropic Squeezing Properties of Squeezed Evan and Odd Coherent States

Abstract

The influence of coherent state strength,phase angle and squeezing parameter on position and momentum entropic squeezing for squeezed even and odd coherent were discussed by numerical calculations.The results show that both the two states exhibit the entropic squeezing,and the maximum squeezing in squeezed even coherent state is greater than that of squeezed odd coherent state.The squeezing is related to the strength of coherent state,phase angle and squeezing parameter,in which the squeezing is related to the strength of coherent state,phase angle and squeezing parameter,in which the squeezing parameter is the principal factor.The squeezing of position entropy (or momentum entropy) for squeezed even coherent state will reach its maximum under the condition that the squeezing parameter ｜β｜=0.95 and other parameters are fixed.But this character does not exist in squeezed odd coherent state.

Entropic Squeezing Properties of Superposition Coherent States

Yun‐Jie Xia

We study the position and momentum entropic squeezing for superposotion coherent states in this paper. The influence of coherent state strength,phase angle and superposition coefficect on the spueezing are discussed by numerical calculations. The results show that both the two states exhibit the entropic squeezing. The squeezing is related to the strength of coherent state, phase angle and superposition coefficient,in which the superposition coefficient is the principal facor.

ENTROPIC SQUEEZING PROPERTIES OF EVEN AND ODD COHERENT STATES

Yongping Li, Yun‐Jie Xia

The position and momentum entropic squeezing of even and odd coherent states are studied. The relations between the two entropic squeezings and the two quadrature components squeezing are also discussed. The results show that even and odd coherent state exhibits both position and momentum entropic squeezing, which is different from the standard deviations squeezing.

The entropic squeezing of superposition of two arbitrary coherent states

LU Dao-ming

In this paper the superpositions of two arbitrary coherent states |Ψ〉 = a |β〉 + b e iϕ |mβe iδ 〉 are constructed by using the superposition principle of quantum mechanics. The entropic squeezing effects of the quantum states are studied. The numerical results indicate that the amplitudes, the ratio between the amplitudes of two coherent states, the phase difference between the two components and the relative phase of the two coefficients play important roles in the squeezing effects of the position entropy and momentum entropy.
