FINITE-DIMENSIONAL SQUEEZED VACUUM AND ITS GENERATION 1
Adam Miranowicz · 1998
A squeezed vacuum in a finite-dimensional Hilbert space (FDHS) is defined. Its explicit Fock expansion is found. We show that our state goes over into the standard squeezed vacuum if the squeeze parameter squared is much less than the dimension of FDHS. A method to generate finite-dimensional squeezed vacuum is proposed. 1
