Chirality in Quantum Computation with Spin Cluster Qubits
arXiv:cond-mat/0403444 · doi:10.1103/PhysRevLett.93.120503
Abstract
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.
