Daniel Gottesman - Quantum Error Correction and Fault Tolerance (Part 1) - CSSQI 2012

Dr. Daniel Gottesman, Research Scientist at the Perimeter Institute for Theoretical Physics, gave a lecture about Quantum Error Correction and Fault Tolerance.
The lecture is the first of two parts, and was filmed at the Canadian Summer School on Quantum Information, held at the University of Waterloo in June of 2012.

One of the finest introductions to stabilizer formalism!

[@jiliu8071]

Great video for introducing stabilizer formalism

[@KishorBharti1]

Interesting
The stabilizer formalism is awesome.

[@jxchtajxbt53]

Expert presentation

[@HidekazuOki]

I don't quite understand what the notation |I> and |Z^k> stands for.... I thought I is the identity matrix and Z^k likewise a matrix operator of some sort but why are they inside a ket?

I'm looking at the slides at 24:49 which talks about continuous errors.

[@danielmiller8800]

@26:00 are alpha beta gamma delta at the decomposition real or complex numbers?

[@qingbinluo5964]

they are real numbers.

[@danielmiller8800]

just found out that they are not
cs.uwaterloo.ca/~watrous/CPSC519/LectureNotes/17.pdf
this makes a lot more sense

[@jonabirdd]

@@danielmiller8800 they are two complex numbers up to overall phase.

[@danielmiller8800]

@@jonabirdd No, they are not. They are four ordinary complex numbers.

Mathematical algorithm of self-error correction will involve new technology, reducing noise etc. We don't have the algorithm and may have a rudimentary form of it. The universe is a QC function of 140,000 qubits. Life is also a QC function, perhaps 500-800 qubits. We may never find the algorithm of a full blown QC function.
