Quantum fault tolerance is the capability of a quantum computer to continue functioning correctly despite the presence of errors in its quantum bits (qubits). This concept is crucial for ensuring that quantum algorithms can be executed reliably over long periods, especially since qubits are highly susceptible to noise and decoherence. By implementing error correction codes and various techniques, quantum fault tolerance allows distributed quantum systems to maintain consistent performance, even when faced with disturbances that could affect computation.
congrats on reading the definition of quantum fault tolerance. now let's actually learn it.
