Quantum Error Correction is a method used in quantum computing to protect quantum information from errors due to decoherence and other disturbances. Unlike classical error correction, which can simply duplicate information, quantum error correction uses entangled states to encode data in a way that allows for the detection and correction of errors without measuring the quantum state directly. This technique involves creating redundant quantum bits, or qubits, that work together to ensure the integrity of the information. By using specific algorithms, quantum error correction can identify and fix errors, making it essential for the development of reliable quantum computers capable of performing complex calculations.
