Quantum kittens, cats, combs and compasses: superposing coherent states for sensing, communication, computing and pleasure

Superpositions of coherent states, which have minimum uncertainty and follow, at least transiently, classical motion, constitute codes for quantum computing, enhance quantum communication and are advantageous for quantum sensing and metrology. I present a potted history of this field followed by our proposal for making a nuclear cat state reported in arXiv:2304.13813.
