Mean spin direction and spin squeezing in superpositions of spin coherent states

Abstract We consider the mean spin direction (MSD) of superpositions of two spin coherent states (SCS) | ± μ〉, and superpositions of | μ〉 and | μ*〉 with a relative phase. We find that the azimuthal angle exhibits a π transition for both states when we vary the relative phase. The spin squeezing of the states, and the bosonic counterpart of the mean spin direction are also discussed.

Spin squeezing and entanglement in superposition of nonlinear spin coherent states

We study squeezing and entanglement in superposition of a class of nonlinear spin coherent states. We analyze these properties as a function of the coherence and superposition parameters, number of qubits and the Hamiltonians involved, by presenting analytical and numerical results. We specifically observe that a subclass of these states, the even non-linear cat states are maximally entangled and squeezed, while another related subclass, the odd non-linear cat states, are entangled but not squeezed at all.

Linear amplifier via the squeezed coherent states superpositions

G. M. Abd Al-Kader

Much attention is given for the squeezed coherent states (SCS's) superposition. The s -parameterized charactristic function (CF) for the output field with the superposition of SCS's as input field is given. The s -parameterized quasiprobability distribution function (QDF) for the output field with superposition of SCS's as input state are investigated. Various moments are calculated by using the s -parameterized CF for that field. The Glauber second-order coherence function is calculated. The quadrature squeezing for the output field are discussed. Some QDF's of the output fields are plotted as functions of the interaction time. Phase properties of the superpostion of SCS's are studied. The s -parameterized phase distributions obtained by integrating the s -parameterized QDF over radial variable are illustrated.
