1210.3473 (Ulrik L. Andersen)

Heralded generation of the Optical Schrodinger Cat State    [PDF]

Ulrik L. Andersen
Using a simple optical setup I show how optical entanglement between a macroscopic and a microscopic state - the so-called Schrodinger Cat state or micro-macro state - can be generated. The entangled state is heralded and is thus produced a priori in contrast to previous proposals. A simple variant of the scheme allows for the preparation of the entangled state at distant sides connected with a lossy link. Furthermore, I show that the state can be used to map a microscopic qubit onto a macroscopic one thereby linking the qubit processor with a qumode processor.
