An Elementary Characterization of Bargmann Invariants

Sagar Silva Pratapsi, João Gouveia, Leonardo Novo +1

Bargmann invariants, also known as multivariate traces of quantum states $\mathrm{Tr}(\ddot{I}{}_1\ddot{I}{}_2\cdots \ddot{I}{}_n)$, are unitary invariant quantities used to characterize weak valu…
