Alternating Squeezing and Photon Subtraction for Optical Cat-State Generation
The research explores generating Schrödinger cat states using alternating squeezing and photon-number subtraction instead of simple subtraction from squeezed vacuum. By framing this as a fidelity-constrained multibranch optimization, the study shows that alternating schemes improve generation probability and fidelity compared to single subtractions, especially under experimental constraints like limited photon-number resolution.
