Quantum-state engineering via discrete coherent-state superpositions
József Janszky, P. Domokos, Sandor Szabo, Петер Адам · Physical Review A · 1995
A representation of a Fock state \ensuremath{\Vert}n〉 is given by a superposition of n+1 coherent states. These discrete coherent-state superpositions provide experimental possibilities for generating an arbitrary quantum state of a single-mode electromagnetic field.
