Nearly tight bounds for testing tree tensor network states
Benjamin Lovitz, Angus Lowe
Tree tensor network states (TTNS) generalize the notion of having low Schmidt-rank to multipartite quantum states, through a parameter known as the bond dimension. This leads to su…

Optimal quantum circuit cuts with application to clustered Hamiltonian simulation
Aram W. Harrow, Angus Lowe
We study methods to replace entangling operations with random local operations in a quantum computation, at the cost of increasing the number of required executions. First, we cons…
