A multiphoton heralding protocol in an OPA produces large-amplitude squeezed cat states and parity-selective Fock superpositions from squeezed vacuum, with claimed Wigner negativity, phase-space complexity, and loss resilience.
These probabilities are comparable to those of other heralded non-Gaussian state schemes (e.g., mutli-photon-added coherent states [7] and cluster states [72])
