Logical Qubits
A logical qubit is a virtual qubit created by using several physical qubits to protect and preserve quantum information. Logical qubits are the error-protected version of quantum bits and are….

Concatenated Codes
Concatenated codes are a technique used in quantum error correction (QEC) to amplify protection against errors by combining two or more error correction codes in a nested way — like….
Surface Codes
Surface codes are one of the most promising methods for quantum error correction (QEC). In simple terms, they are used to protect quantum information from errors — which is essential….
