Generating and revealing a quantum superposition of electromagnetic-field binomial states in a cavity
Rosario Lo Franco, Giuseppe Compagno, ANTONINO MESSINA, Anna Napoli · Physical Review A · 2007
We introduce the $N$-photon quantum superposition of two orthogonal generalized binomial states of an electromagnetic field. We then propose, using resonant atom-cavity interactions, nonconditional schemes to generate and reveal such a quantum superposition for the two-photon case in a single-mode high-$Q$ cavity. We finally discuss the implementation of the proposed schemes.
