We have investigated the intensity squeezing of superposition of two photon-added coherent states and proposed a new method for preparation of photon-added coherent states and their superposition states. This method is based on interaction of the trapped ion with the traveling wave light fields with different frequencies.

Engineering of Schrödinger cat states by a sequence of displacements and photon additions or subtractions

Sergey A. Podoshvedov

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.
