New schemes for creating large optical Schrödinger cat states using strong laser fields

Recently, using conditioning approaches on the high-harmonic generation process induced by intense laser-atom interactions, we have developed a new method for of optical Schrödinger cat states (Lewenstein et al. in Nat Phys, 17 1104–1108, 2021. https://doi/10.1038/s41567-021-01317-w). These quantum been proven to be very manageable as, modifying conditions under which harmonics are generated, one can interplay between kitten and genuine states. Here, demonstrate that this also used development schemes towards creation states, consisting superposition three distinct coherent Apart from interest these kind their own, additionally propose scheme them large involving sum two different The properties obtained superpositions aim significantly increase applicability technology information processing.
