Implementation and representation of qudit multi-controlled unitaries and hypergraph states by N-body angular momentum couplings

2025 · arXiv (Cornell University)

We construct a representation of qudit multi-controlled unitary operators in terms of N-body angular momentum interactions. The representation is particularly convenient for odd-dimensional systems, with interesting connections to the Pegg-Barnett phase formalism. We illustrate the …
