Locally accurate MPS approximations for ground states of one-dimensional gapped local Hamiltonians
Alexander M. Dalzell, Fernando G. S. L. Brandao
A key feature of ground states of gapped local 1D Hamiltonians is their relatively low entanglement --- they are well approximated by matrix product states (MPS) with bond dimensio…

How many qubits are needed for quantum computational supremacy?
Alexander M. Dalzell, Aram W. Harrow, Dax Enshan Koh +1
Quantum computational supremacy arguments, which describe a way for a quantum computer to perform a task that cannot also be done by a classical computer, typically require some so…
