Kvantbitid
Kvantbitid, often translated as qubit, is the fundamental unit of quantum information. Unlike classical bits that can only represent either a 0 or a 1, a qubit can exist in a superposition of both states simultaneously. This means a qubit can be 0, 1, or a combination of both with certain probabilities. This ability to represent multiple states at once is a key principle that enables quantum computers to perform certain calculations exponentially faster than classical computers.
The state of a qubit is typically represented by a vector in a two-dimensional complex vector space.
The unique properties of qubits, such as superposition and entanglement, are harnessed by quantum computers to
