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….

Fault-Tolerant Quantum Gates
Fault-tolerant quantum gates are quantum operations that are designed to work correctly even when some parts of the system experience small errors. In simpler terms: They are the “error-proof” buttons….
Syndrome Measurement
Syndrome measurement is the process of detecting which error (if any) has affected a quantum state—without destroying the quantum information itself. In simple terms: Syndrome measurement is like a quantum….
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….
