What lies ahead for topological photonic systems?

The final day of the Topological Order with Photons Incubator saw several more proposals for systems that could support topological edge states. Metamaterials are a promising environment, and talks were given by Alex Kanikaev and Gennady Shvets on fabricating bianistropic metamaterials to emulate electron spins and topological insulators. Na Young Kim and Alberto Ano laid different schemes for creating lattices of exiton-polariton microcavities, as well as roadmaps for potentially seeing topological effects in these systems.

How do you make a topologically interesting system with light?

Quantum superposition states are immensely delicate things - any interaction with the environment can cause them to decohere. This poses a significant problem for quantum computing, where information would need to be stored within quantum states for relatively long periods of time. A promising way to isolate a system exploits the topology of the system, known as 'topological protection'. A state that is topologically isolated from its environment would be perfectly shielded from the sort of noise and environmental imperfections that creep into quantum systems now.

OSA Topological Order with Photons Incubator: Facilitating Discussion of this Nascent Field

Posted by Sean Kelley | Apr 4, 2014 9:09:00 AM

Greetings from the 12th installment of OSA Incubator meetings, the OSA Topological Order with Photons Incubator! Hosted by Steven Girvin, Yale University, United States; Mohammad Hafezi, Joint Quantum Institute, United States; Karyn Le Hur, Ecole Polytechnique, France; Jacob Taylor, National Institute of Standards & Technology, United States; the meeting will span two days, involving formal talks, informal discussion, and impressive coffee consumption. Sponsors include the Air Force Office of Scientific Research, the Army Research Office, Joint Quantum Institute and the Physics Frontier Center.
