  Mappings between fermions and qubits are valuable constructions in physics.
To date only a handful exist. In addition to revealing dualities between
fermionic and spin systems, such mappings are indispensable in any quantum
simulation of fermionic physics on quantum computers. The number of qubits
required per fermionic mode, and the locality of mapped fermionic operators
strongly impact the cost of such simulations. We present a novel fermion to
qubit mapping which outperforms all previous local mappings in both the qubit
to mode ratio, and the locality of mapped operators.
