Preparation of Schrödinger cat quantum state using parametric down-conversion interaction

Published 8 Jul 2024 in quant-ph | (2407.05759v3)

Abstract: The Schr\"odinger cat (SC) states are important in quantum optics because of their non-Gaussian properties. We propose a novel method of conditional generation of bright (multi-photon) SC states that uses degenerate parametric down-conversion and heralding measurement of the photon number in the pump mode. We show that this method, in principle, could be implemented using the modern high-(Q) optical microresonators.
