Introduction to Quantum Error Correction Part 2: Geometrically Local Quantum Codes (Session 12 of RIT in Quantum Information Science) Speaker Name: Xiaozhen Fu Speaker Institution : UMD Â
The goal of this talk is to give an overview of the advantages and disadvantages of having geometric locality in quantum error-correcting codes. Starting with an introduction to the surface code, I will highlight the nice features of a geometrically local 2D stabilizer code. However, we will also examine the limitations that arise from imposing geometric locality, and how these limitations come about, particularly with regard to the code parameters and the allowable set of logical gates. Finally, we will explore some interesting techniques such as magic state distillation and code-switching that can be used to overcome these limitations.
