Viv Kendon: Ancilla mediated quantum gates

Viv Kendon, Durham University

Practical quantum gate operations for quantum computing usually take
advantage of extra degrees of freedom in a physical qubit system or use
an extra, ancilla, system. For example, the collective vibrational
modes of ions in a trap are used for the Cirac-Zoller gate. I will
describe our search for the simplest forms of ancilla-controlled quantum
operations. Solving this theoretical puzzle can potentially lead us to
simpler designs for quantum computers that are easier to build. This
work was done with my collaborators, especially my PhD student Tim
Proctor (Leeds), and also Shane Dooley (Leeds), and Erika Andersson
(Heriot-Watt).
