Uniquely determined pure quantum states need not be unique ground states of quasi-local Hamiltonians
Salini Karuvade, Peter D. Johnson, Francesco Ticozzi +1
We consider the problem of characterizing states of a multipartite quantum system from restricted, quasi-local information, with emphasis on uniquely determined pure states. By lev…

On state vs. channel quantum extension problems: exact results for UxUxU symmetry
Peter Johnson, Lorenza Viola
We develop a framework which unifies seemingly different extension (or "joinability") problems for bipartite quantum states and channels. This includes well known extension problem…
