Abstract
A method to generate Schrödinger cat states in free propagating optical fields based on the use of displaced states (or displacement operators) is developed. Some optical schemes with photon-added coherent states are studied. The schemes are modifications of the general method based on a sequence of displacements and photon additions or subtractions adjusted to generate Schrödinger cat states of a larger size. The effects of detection inefficiency are taken into account.
