Freedman's theorem for unitarily invariant states on the CCR algebra

Vitonofrio Crismale, Simone Del Vecchio, Tommaso Monni +1

The set of states on $\mathrm{CCR}(\mathrm{ch})$, the CCR algebra of a separable Hilbert space $\mathrm{ch}$, is here looked at as a natural object to obtain a non-commutative version of Freedman's t…
