A toolbox for lattice-spin models with polar molecules

- A. Micheli, G. Brennen, P. Zoller
- Physics
- 23 December 2005

There is growing interest in states of matter with topological order. These are characterized by highly stable ground states robust to perturbations that preserve the topology, and which support… Expand

QUANTUM LOGIC GATES IN OPTICAL LATTICES

- G. Brennen, C. Caves, P. Jessen, I. Deutsch
- Physics
- 6 June 1998

We propose a new system for implementing quantum logic gates: neutral atoms trapped in a very far-off-resonance optical lattice. Pairs of atoms are made to occupy the same well by varying the… Expand

Entanglement dynamics in one-dimensional quantum cellular automata

- G. Brennen, Jamie E. Williams
- Physics
- 6 June 2003

Several proposed schemes for the physical realization of a quantum computer consist of qubits arranged in a cellular array. In the quantum circuit model of quantum computation, an often complex… Expand

Quantum magnetomechanics: ultrahigh-Q-levitated mechanical oscillators.

- M. Cirio, G. Brennen, J. Twamley
- Physics, MedicinePhysical review letters

Canonical decompositions of n-qubit quantum computations and concurrence

- S. Bullock, G. Brennen
- Mathematics, Physics
- 12 September 2003

The two-qubit canonical decomposition SU(4)=[SU(2)⊗SU(2)]Δ[SU(2)⊗SU(2)] writes any two-qubit unitary operator as a composition of a local unitary, a relative phasing of Bell states, and a second… Expand

Measurement-based quantum computer in the gapped ground state of a two-body Hamiltonian.

Parallelism for quantum computation with qudits

- D. O’Leary, G. Brennen, S. Bullock
- Physics
- 9 March 2006

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 implement parallel… Expand

Efficient circuits for exact-universal computationwith qudits

Quantum walks with memory provided by recycled coins and a memory of the coin-flip history

- P. Rohde, G. Brennen, A. Gilchrist
- Physics
- 2 May 2013

Quantum walks have emerged as an interesting approach to quantum information processing, exhibiting many unique properties compared to the analogous classical random walk. Here we introduce a model… Expand
