Machine Learning based decoding in Quantum Error Correction

Surface codes

Surface codes are currently the leading archi­tec­ture for practi­cal quantum error correc­tion and are widely regarded as one of the most promi­sing approa­ches due to their…

Color codes

Color codes are topolo­gi­cal quantum error correc­tion codes that encode logical qubits within a two dimen­sio­nal lattice whose faces can be colored using three distinct colors. This struc­ture enables…

Quantum LDPC Codes

Quantum Low Density Parity Check (qLDPC) codes are a class of quantum error correc­tion codes designed to protect quantum infor­ma­tion from noise using sparsely connec­ted parity constraints. Analog­ous to their…

Cat Qubits

Cat qubits are quantum bits encoded in Schrö­din­ger cat states, that is, in super­po­si­ti­ons of two coher­ent states of a harmo­nic oscil­la­tor, typically micro­wave photons stored within a…

Self Correc­ting Quantum Codes

Self-correc­ting quantum codes passi­vely protect data via…

Perfect matching

Perfect matching decoding is an error correc­tion approach that is widely used in topolo­gi­cal quantum error correc­tion codes such as the Surface Code. The central idea is that…

Cluste­ring

In quantum error correc­tion, classi­cal decoders inter­pret error signa­tures (syndro­mes) to fix qubits. Cluste­ring is an…

Magic Gate iIjection

Fault tolerant quantum compu­ters rely on quantum error correc­tion codes. However, these codes typically support only a limited…

Code switching

Code switching refers to the process of dynami­cally changing the error correc­tion code used to protect quantum infor­ma­tion, often in order to…

Lattice Surgery

Lattice surgery is a method for imple­men­ting logical gate opera­ti­ons between qubits encoded in topolo­gi­cal quantum error correc­tion codes, particularly…
