*Classical Information* is the type of information we handle in everyday computing, communication, and data storage, governed entirely by the rules of [[Classical Physics|classical physics]]. It is represented using [[Bit|bits]], which must be in a definite state of 0 or 1. This deterministic nature makes classical information easy to copy and transmit—when you duplicate a file on your [[Classical Computer|computer]], you are replicating classical bits without altering their original state. However, classical information lacks some of the properties found in quantum systems, so it cannot take advantage of [[Superposition|superposition]] or [[Entanglement|entanglement]]. Classical computers are highly effective and power countless applications, yet they inevitably reach a fundamental limit—this is where [[Quantum Technologies|quantum technologies]], founded on the unique properties of [[Quantum Information|quantum information]], offer entirely new possibilities. >[!read]- Further Reading >- [[Bit]] >- [[Quantum Information]] >- [[Classical Computer]] >[!ref]- References >- C.
