“…There has been a variety of recent proposals to manufacture NOON states that include the use of trapped ions [16], waveguide arrays [17], ultracold bosons [18][19][20], double-slit interference [21], magnons [22], cavity quantum electrodynamics (QED) [23], and circuit QED [24]. One proposal for massive NOON state generation uses a system of dipolar atoms confined to a four-site lattice [25,26].…”

A recently proposed extended Bose–Hubbard model, one that is a quantum integrable model, provides a framework for a NOON state generation protocol. Here we derive a Bethe ansatz solution for the model. The form of the solution provides the means to obtain exact asymptotic expressions for the energies and eigenstates. These results are used to derive formulae for measurement probabilities and outcome fidelities. We benchmark these results against numerical calculations.
