), a qubit can exist in a of both states simultaneously.
: Operations (like the Hadamard or CNOT gates) that manipulate qubit states to perform computations, forming Quantum Circuits . 2. Quantum Error-Correcting Codes (QECCs) thequantumcodes
Because quantum states are fragile, codes are used to "spread" information across multiple physical qubits to protect a single "logical" qubit. ), a qubit can exist in a of both states simultaneously
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 2]] or [[8
: 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.
