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

), a qubit can exist in a of both states simultaneously. thequantumcodes

To understand quantum codes, you must first master the building blocks of quantum information: : Operations (like the Hadamard or CNOT gates)

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

: A simple introductory code where a logical state is repeated across multiple qubits to guard against bit-flips. 3. Essential Programming Frameworks Introduction to the Quantum Programming Language Q#

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