Please join us on Wednesday, September 17 at 4pm in the Time room for
a quantum information seminar by Mark Howard.

Title:  A magic bullet for numerous quantum-informational tasks
Speaker: Mark Howard

Abstract: A class of d-level quantum states called "magic states",
whose initial purpose was to enable universal fault-tolerant
computation within error-correcting codes, has a surprisingly broad
range of applications. We begin by describing their structure with
respect to the Clifford hierarchy, and in terms of convex geometry
before proceeding to their applications. They appear to have some
relevance to the search for SIC-POVMs in certain prime dimensions. A
version of the CHSH non-local game, using a d-ary alphabet and Pauli
measurements, has an optimal quantum strategy using magic states.
Finally, magic states exhibit nice symmetries (balanced, minimum
uncertainty) with respect to Pauli measurements and consequently could
find applications in areas like cryptography.
