Cavity-QED state reduction method to produce atomic Schrödinger-cat states
Christopher C. Gerry, R. Grobe · Physical Review A · 1998
Collective atomic Schr\"odinger-cat states are superpositions of distinct atomic coherent states (or Bloch states). We show how even and odd atomic states can be generated in cavity QED by the use of a dispersive interaction between the atoms and the field along with state reduction.
