SUMMARY:Paving an enlightened path to anyons and quantum computation - Dr 
 Shovan Dutta (Physics Department\, Cambridge)

DESCRIPTION:In a 3D world\, all fundamental particles fall into one of two
  categories: those that behave like photons which make up light\, and thos
 e that behave like electrons which make up matter. However\, more exotic p
 articles can arise in 2D\, called anyons\, which could form the hardware o
 f future quantum computers\, thanks to their fractional exchange statistic
 s. Directly observing anyons is a major challenge of contemporary physics.
  In this talk\, I will present a newly-developed protocol for preparing an
 yons in an optical cavity built by carefully aligning a set of high-qualit
 y mirrors. I will explain how one can drive the cavity with lasers to inje
 ct photons one by one\, building up a “fractional quantum Hall” state.
  Additional lasers are used to create anyonic “hole” excitations and m
 ove them around one another. The resulting phases are measured by interfer
 ometry. I will discuss the challenges of implementing the protocol by anal
 yzing experimental constraints.
