Example Concept: Quantum entanglement creates correlations between qubits, meaning that an error affecting one qubit can influence the state of another entangled qubit. This can lead to correlated errors, where a single error event affects multiple qubits simultaneously. In quantum error correction, such as in the surface code, entanglement is used to detect and correct these errors by measuring syndromes that indicate the presence of correlated errors, allowing for their correction without directly measuring the qubits' states.
