Spin of a multielectron quantum dot and its interaction with a neighboring electron
Filip K. Malinowski, Frederico Martins, Thomas B. Smith +8
We investigate the spin of a multielectron GaAs quantum dot in a sequence of nine charge occupancies, by exchange coupling the multielectron dot to a neighboring two-electron doubl…
Tensor Networks with a Twist: Anyon-permuting domain walls and defects in PEPS
Jacob C. Bridgeman, Stephen D. Bartlett, Andrew C. Doherty
We study the realization of anyon-permuting symmetries of topological phases on the lattice using tensor networks. Working on the virtual level of a projected entangled pair state,…
Long-range entanglement for spin qubits via quantum Hall edge modes
Samuel J. Elman, Stephen D. Bartlett, Andrew C. Doherty
We propose and analyse a scheme for performing a long-range entangling gate for qubits encoded in electron spins trapped in semiconductor quantum dots. Our coupling makes use of an…
