Encoded Universality from a Single Physical Interaction
J. Kempe, D. Bacon, D. P. DiVincenzo +1
We present a theoretical analysis of the paradigm of encoded universality, using a Lie algebraic analysis to derive specific conditions under which physical interactions can provid…
Classical simulation of noninteracting-fermion quantum circuits
Barbara M. Terhal, David P. DiVincenzo
We show that a class of quantum computations that was recently shown to be efficiently simulatable on a classical computer by Valiant corresponds to a physical model of noninteract…
Anisotropic Spin Exchange in Pulsed Quantum Gates
N. E. Bonesteel, D. Stepanenko, D. P. DiVincenzo
We show how to eliminate the first-order effects of the spin-orbit interaction in the performance of a two-qubit quantum gate. Our procedure involves tailoring the time dependence…
Quantum Data Hiding
David P. DiVincenzo, Debbie W. Leung, Barbara M. Terhal
We expand on our work on Quantum Data Hiding -- hiding classical data among parties who are restricted to performing only local quantum operations and classical communication (LOCC…
