Paper Abstract
A "Schrödinger cat" state of free-propagating light can be defined as a quantum superposition of well separated
coherent states. 1, 2 We demonstrated, theoretically and experimentally, a protocol which allows to generate
arbitrarily large squeezed Schrödinger cat states, using a homodyne detection and photon number states as
resources. We implemented this protocol experimentally with light pulses containing two photons, producing a
squeezed Schrödinger cat state with a negative Wigner function. This state clearly presents several quantum
phase-space interference fringes between the "dead" and "alive" components, and it is large enough to become
useful for experimental tests of quantum theory and quantum information processing.
