Title: Novel methods for robust quantum computation

Speaker: Dave Bacon, University of Washington

Location: Building 980, Room 95 (Sandia NM)

Brief Abstract: In this talk I will describe two different paths towards the eventual construction of a robust error-free quantum computer.  The first, more conventional, path involves designing complex micro-architectures which are responsible for performing fault-tolerant quantum error correction.  For this path it is imperative that the quantum codes used in these systems mesh with the design parameters of physical system being used for the quantum computer.  Along these lines I will discuss a new class of quantum error correcting codes, called subsystem quantum error correcting codes, which possess many useful properties as a possible microarchitecture.  The second path I will discuss in this talk involves a less conventional method for achieving robust error-free quantum computers.  In this approach one designs a strongly interacting quantum system which has a quantum error correcting code as the system's ground state.  Further these systems are designed such that error correction is performed simply by keeping the system cold.  Such self-correcting quantum memories could considerabl
