Opening slide of my presentation on Quantum Error Correction at Durham Uninversity. Slide features a picture of the Durham student union and Kingsgate bridge, famously designed by legendary North Eastern arcitect Ove Arup and considered to be one of the world's finest examples of brutalist architecture.
A banner showing a photo of Joschka Roffe. The following text is superimposed on the photo: "Joschka Roffe awarded EPSRC Quantum Technology Career Acceleration Fellowship". The University of Edinburgh School of Informatics logo and the UKRI EPSRC logo are also included in the banner.
This image shows a threshold plot. The breakeven line is superimposed. I am explaining the difference.
Image displays two representations of a QEC protocol. The first uses the traditional circuit notation and the second a Tanner graph notation similar to that used for classical LDPC codes.
The circuit for the [[9,1,3]] Shor code. This QEC protocol is constructed by concatenating the 3-qubit phase-flip repetition code with the 3-qubit bit-flip repetition code.
