[Aspuru-Guzik group list] Special group meeting Thursday 4 PM, Matt Broome

We have a special group meeting Thursday 21, 4 PM at Naito 030 by a visitor of our group, Matthew Broome, from the School of Mathematics and Physics of the University of Queensland. The abstract is here: *The quantum walk, the quantum version of its classical counterpart the random walk, has received a lot of attention in the past few years both inside and outside of the laboratory. The quantum walk has been proposed as a valuable tool for quantum computation in addition to investigating phenomenon such as Anderson localisation and even energy transport in biological systems. I will give a description of our experimental implementation for the discrete-time quantum walk with single photons in space and show how we tuned the level of decoherence in the system from completely quantum right through to the classical random walk. I will also show the most recent application of the experiment: investigating topological phases with discrete time quantum walks. * -- Joel Yuen-Zhou PhD candidate in Chemical Physics Harvard University CCB, 12 Oxford St. Mailbox 107, Cambridge, MA, USA.
