Designing spin-1 lattice models using polar molecules
Gavin K. Brennen, Andrea Micheli, Peter Zoller
We describe how to design a large class of always on spin-1 interactions between polar molecules trapped in an optical lattice. The spin degrees of freedom correspond to the hyperf…
Single qubit gates with a charged quantum dot using minimal resources
Francois Dubin, Gavin K. Brennen
We investigate coherent control of a single electron trapped in a semiconductor quantum dot. Control is enabled with a strong laser field detuned with respect to the electron light…
Qudit surface codes and gauge theory with finite cyclic groups
Stephen S. Bullock, Gavin K. Brennen
Surface codes describe quantum memory stored as a global property of interacting spins on a surface. The state space is fixed by a complete set of quasi-local stabilizer operators…
Parallelism for Quantum Computation with Qudits
Dianne P. O'Leary, Gavin K. Brennen, Stephen S. Bullock
Robust quantum computation with d-level quantum systems (qudits) poses two requirements: fast, parallel quantum gates and high fidelity two-qudit gates. We first describe how to im…
A toolbox for lattice spin models with polar molecules
A. Micheli, G. K. Brennen, P. Zoller
There is growing interest to investigate states of matter with topological order, which support excitations in the form of anyons, and which underly topological quantum computing.…
