A magnonic beamsplitter (BS) operation forms when the system is strongly coupled (Δω≪κ) for a time such that the probability for single magnon scattering between resonators is ½. Applying the BS pulse to a two-magnon initially unentangled state │11〉 generates a maximally entangled N00N state (│20〉+eiθ│02〉)/√2. Shaping the magnetic field profile can tune the sensitivity of the magnonic BS to generate and detect (being a unitary operation) different relative phases θ of the N00N state. Such tunable magnonic BS that can manipulate N00N states could be useful for the quantum metrology of hybrid magnonic systems.
