Topological Order, Dimerization, and Spinon Deconfinement in Frustrated Spin Ladders
Eugene H. Kim, Ö. Legeza, J. Sólyom
We consider topological order and dimer order in several frustrated spin ladder models, which are related to higher dimensional models of current interest; we also address the occu…
Controllability and universal three-qubit quantum computation with trapped electron states
L. H. Pedersen, C. Rangan
We show how to control and perform universal three-qubit quantum computation with trapped electron quantum states. The three qubits are the electron spin, and the first two quantum…
Overcoming the su(2^n) sufficient condition for the coherent control of n-qubit systems
R. Cabrera, C. Rangan, W. E. Baylis
We study quantum systems with even numbers N of levels that are completely state-controlled by unitary transformations generated by Lie algebras isomorphic to sp(N) of dimension N(…
Average Fidelity in n-Qubit systems
R. Cabrera, W. E. Baylis
This letter generalizes the expression for the average fidelity of single qubits, as found by Bowdrey et al., to the case of n qubits. We use a simple algebraic approach with basis…
