Because quantum states are fragile, codes are used to "spread" information across multiple physical qubits to protect a single "logical" qubit.

: Operations (like the Hadamard or CNOT gates) that manipulate qubit states to perform computations, forming Quantum Circuits . 2. Quantum Error-Correcting Codes (QECCs) thequantumcodes

: A phenomenon where qubits become linked; the state of one instantly affects another, regardless of distance. This is crucial for error correction. Because quantum states are fragile, codes are used

Quantum codes primarily refer to , which are essential for protecting quantum information from noise and decoherence. This guide covers the fundamental concepts, popular coding frameworks, and steps to begin programming quantum machines. 1. Core Concepts of Quantum Information

To understand quantum codes, you must first master the building blocks of quantum information:

: The basic unit of quantum information. Unlike classical bits (
