Conditional generation of optical Schrödinger cat states
arXiv:1511.06531 · doi:10.1088/0031-8949/2010/T140/014011
Abstract
Given a source of two coherent state superpositions with small separation in a traveling wave optical setting, we show that by interference and balanced homodyne measurement it is possible to conditionally prepare a symmetrically placed superposition of coherent states around the origo of the phase space. The separation of the coherent states in the superposition will be amplified during the process.
