Heralded dissipative preparation of nonclassical states in a Kerr oscillator
Martin Koppenhöfer, Christoph Bruder, Niels Lörch · Physical Review Research · 2020
Photon-counting measurements induce a continuous time evolution between adjacent photon detection events, which is defined by a non-Hermitian Hamiltonian. The authors show that this time evolution relaxes the system towards a deterministic state. This effect can be used to prepare various nonclassical states, including Schr\"odinger kitten states
