Implementation and representation of qudit multi-controlled unitaries and hypergraph states by N-body angular momentum couplings
F. E. S. Steinhoff
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-di…

Characterizing resources for multiparameter estimation of SU(2) and SU(1,1) unitaries
Shaowei Du, Shuheng Liu, Frank E. S. Steinhoff +1
We analyze the task of estimating a multi-parameter unitary belonging to the or groups, in a two-bosonic-mode scenario and investigate the scaling of the precisio…
