Chirality in Quantum Computation with Spin Cluster Qubits
V. W. Scarola, Kimin Park, S. Das Sarma · Physical Review Letters · 2004
We study corrections to the Heisenberg interaction between several lateral, single-electron quantum dots. We show, using exact diagonalization, that three-body chiral terms couple triangular configurations to external sources of flux rather strongly. The chiral corrections impact single-qubit encodings utilizing loops of three or more Heisenberg coupled quantum dots.
