Quantum Information Talks

• Distance and Bounds
• Introduction to the Stabilizer Formalism
• Quantum Circuits
• A brief review of error correction concepts necessary for fault tolerant quantum computation
• A Lecture on Fault Tolerance
• Review of the paper, "Exact Performance of Concatenated Codes"
• Fault Tolerant Thresholds for Non-Standard Error Models (ppt) - This was my proposal defense. My procedure for making logical plus did not work, so this approach had to be scrapped.
• Symmetric Errors and Fault Tolerance Poster (ppt) - This is the poster I gave at SQuInT.
• Quantum Computing with Symmetry (ppt) - This is the talk I gave to the perspective students.
• Symmetric Errors and Fault Tolerance (ppt) - This is the talk I gave at Los Alamos.
• Rules to be broken (ppt) - My ill fated work on threshold bounds, condensed to a ten minute QuaCGR talk given on 8/2005.
• Threshold Bounds for Steane Protocols (ppt) - This one is perhaps best forgotten. I gave it in 11/2005 at a Los Alamos Quantum Lunch Seminar just before I realized that my work on threshold bounds was all bunk.
• Threshold estimates for arbitrary error models (ppt) - This talk covers my work on threshold estimates for arbitrary error models and homogeneous ancillae. I gave it at SQuInT in February 2006.
• Fault Tolerance and Thresholds (source) - A.K.A. The Art of Fault Tolerance. This is a talk reviewing the fundamentals of fault tolerance and the origin of thresholds for fault tolerant quantum computation. I presented it as the final two lectures for Carl Cave's Quantum Computation class in Spring 2006, http://info.phys.unm.edu/~caves/courses/qcomp-s06/syllabus.html, and again (in part) at Sandia National Labs on the 14th of September 2006.
• Ancillae with Homogeneous Errors (source) - This talk covers my preliminary work on improved methods of ancillae construction. I gave it at the IQI Seminar at Caltech on the 28th of November 2006 and again at Perimeter Institute's Young Researchers Conference on the 7th of December 2006.
• Thresholds for Quantum Computation (source) - This is the tutorial I gave at SQuInT 2007 on the 15th of February about thresholds for fault-tolerant quantum computation.

For Joe

• Channel capacity for CSS codes (source) - This is the an appendix I wrote for my paper on Fault-Tolerant Thresholds for Encoded Ancillae with Homogeneous Errors. Later I discovered that the channel capacity for dual containing CSS codes had been determined by Hamada.
• My BibTex file

Useful code

• Infinite CSS code CX counter 3.nb - This is the the Mathematica code I wrote for calculating encoded error rates, and thereby thresholds.
• If you're looking for Qcircuit, that macro package has it's own site at http://info.phys.unm.edu/Qcircuit/.
