Generation and Properties of Superpositions of Displaced Fock States
H. M. Moya-Cessa · Journal of Modern Optics · 1995
We study the statistical properties of superpositions of displaced Fock states. We find that for the superposition of the form ¦ψ1〉 = 1/√2(¦α, n〉 + ¦α, k〉) the direction of the displacement (α positive or negative) plays an important role; also, if n = 1 and k = 0 a strong sub-Poissonian character is found for α ≥ 0. We also analyse the ways in which superpositions of displaced Fock states may be generated.
