Cat states, Decoherence, and Rotational Smearing in Optomechanical systems

Optomechanical systems~consist of a laser cavity coupled with a moving~microscopic~mirror. Such a system creates cat states which approximate qubits.~Another feature of this system is decoherence effects. Decoherence is~essentially a loss of information when coupled with another system, in this case, loss of rotational information, shown in a phase diagram. Here, we explore the development of these cat states, as well as the effects of decoherence which lead to a rotational smearing effect.~
