 ### 1. The Importance of Quantum Error Correction
 Quantum error correction is a foundational concept in quantum computing, addressing the challenges posed by decoherence and quantum noise. Since quantum systems are highly sensitive to their environment, errors can accumulate during computation, making error correction crucial for reliable quantum operations.
