: A phenomenon where qubits become linked; the state of one instantly affects another, regardless of distance. This is crucial for error correction.
: A major class of codes (e.g., the [[4, 2, 2]] or [[8, 3, 2]] codes) that use "syndrome measurements" to detect and localize errors without destroying the underlying quantum information. thequantumcodes
: Operations (like the Hadamard or CNOT gates) that manipulate qubit states to perform computations, forming Quantum Circuits . 2. Quantum Error-Correcting Codes (QECCs) : A phenomenon where qubits become linked; the
