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….

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….
Quantum Error Correction
1. Why Do We Even Need Error Correction in Quantum Computing? In classical computing: In quantum computing: But unlike classical bits, you can’t just copy a qubit or measure it….
