Local Jordan-Wigner transformations on the torus
Oliver O'Brien, Laurens Lootens, Frank Verstraete
We present a locality preserving unitary mapping from fermions to qubits on a 2D torus whilst accounting for the mapping of topological sectors. Extending the work of Shukla et al.…

Ultrafast Hybrid Fermion-to-Qubit mapping
Oliver O'Brien, Sergii Strelchuk
Fermion-to-qubit mappings play a crucial role in representing fermionic interactions on a quantum computer. Efficient mappings translate fermionic modes of a system to qubit intera…
