\nQubit refers to a two-valued quantity used in quantum computers.
\n<\/section>\n
\nA qubit, or quantum bit, is the basic unit of information in quantum computing. Unlike a classical bit, which can only be 0 or 1, a qubit can be 0, 1, or a superposition of both 0 and 1 simultaneously.
\n<\/section>\n
\nThe ability of qubits to exist in superposition and become entangled is what gives quantum computers their potential power to solve certain problems much faster than classical computers. Classical computers use classical bits (either 0 or 1). Classical cryptography relies on mathematical algorithms solvable by classical computers, though potentially requiring immense computational power. Lasers are devices that emit coherent light; while based on quantum mechanics, the term “qubit” is specific to quantum information processing.
