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.
Time-optimal control produces Fock and Schrödinger cat states in light-matter systems at unit fidelity with lower energetic cost and noise robustness than adiabatic methods.
