Decoherence-free dynamical and geometrical entangling phase gates
Jiannis K. Pachos, Almut Beige
It is shown that entangling two-qubit phase gates for quantum computation with atoms inside a resonant optical cavity can be generated via common laser addressing, essentially, wit…
Topological Quantum Gates with Quantum Dots
Jiannis K. Pachos, Vlatko Vedral
We present an idealized model involving interacting quantum dots that can support both the dynamical and geometrical forms of quantum computation. We show that by employing a struc…
Geometrical phases for the G(4,2) Grassmannian manifold
Regina Karle, Jiannis Pachos
We generalize the usual abelian Berry phase generated for example in a system with two non-degenerate states to the case of a system with two doubly degenerate energy eigenspaces.…
Quantum Computation with a One-Dimensional Optical Lattice
Jiannis Pachos, Peter L. Knight
We present an economical dynamical control scheme to perform quantum computation on a one dimensional optical lattice, where each atom encodes one qubit. The model is based on atom…
