Quantum Error Correction

Quantum Error Correction is a method used to protect quantum information from errors caused by environmental interference or operational imperfections. Unlike classical bits, quantum bits (qubits) can exist in multiple states simultaneously, making them delicate. Quantum Error Correction encodes a logical qubit into multiple physical qubits, creating redundancy. By carefully measuring and correcting errors without directly accessing the quantum information, this technique helps maintain the integrity of quantum computations. As a result, it enables the development of more stable and reliable quantum computers, paving the way for advancements in quantum communication and computation.
