At UBC Physics and Astronomy, we work on the experimental realization of quantum computation as well as its theoretical foundation.
Robert Raussendorf’s research interests are in the theory of quantum computation, specifically computational models, quantum fault-tolerance, and the relation of quantum computation to foundations of quantum mechanics. Raussendorf has invented the one-way quantum computer (QCc) jointly with Hans Briegel (US patent 7,277,872). The QCc is a scheme of universal quantum computation by local measurements on a multi-particle entangled quantum state, the so-called cluster state. The current research in Robert Raussendorf’s group focuses on so-called ``computational phases of quantum matter’’ and the role of contextuality for quantum computation.
Jeff Young, in collaboration with Michael Thewalt and Stephanie Simmons (both Simon Fraser University) and Lukas Chrsotowski (UBC ECE) works on a quantum computer architecture based on donor qubits in silicon, coupled by photonic interconnects
