Topology, Algebraic Geometry, and Dynamics Seminar (TADS): Classical aspects of self-correcting quantum memories

Speaker: Adam Artymowicz, University of Maryland

Title: Classical aspects of self-correcting quantum memories

Abstract:  One of the main challenges in the development of quantum computers is the inherent sensitivity of quantum information to noise. To mitigate this, it is widely accepted that some kind of error correction scheme is necessary. Such schemes can be active or passive, according to whether they require repeated measurements. In this talk I will describe proposals for passive quantum memories, which are based on thermodynamic phases of matter that protect quantum information (analogously to how ferromagnetic materials are used to store classical information). I will describe the mathematics that governs these systems, and how questions about these systems can often be translated into questions in classical lattice statistical mechanics. No familiarity with quantum mechanics will be assumed.
