Decoherence vs entanglement in coined quantum walks
Olivier Maloyer, Viv Kendon
Quantum versions of random walks on the line and cycle show a quadratic improvement in their spreading rate and mixing times respectively. The addition of decoherence to the quantu…
Macroscopic Entanglement and Phase Transitions
Janet Anders, Vlatko Vedral
This paper summarises the results of our research on macroscopic entanglement in spin systems and free Bosonic gases. We explain how entanglement can be observed using entanglement…
Optimal computation with non-unitary quantum walks
Viv Kendon, Olivier Maloyer
Quantum versions of random walks on the line and the cycle show a quadratic improvement over classical random walks in their spreading rates and mixing times respectively. Non-unit…
A random walk approach to quantum algorithms
Viv Kendon
The development of quantum algorithms based on quantum versions of random walks is placed in the context of the emerging field of quantum computing. Constructing a suitable quantum…
Optomechanical entanglement between a movable mirror and a cavity field
D. Vitali, S. Gigan, A. Ferreira +6
We show how stationary entanglement between an optical cavity field mode and a macroscopic vibrating mirror can be generated by means of radiation pressure. We also show how the ge…
Creation of macroscopic superposition states from arrays of Bose-Einstein condensates
J. A. Dunningham, K. Burnett, R. Roth +1
We consider how macroscopic quantum superpositions may be created from arrays of Bose-Einstein condensates. We study a system of three condensates in Fock states, all with the same…
