摘要
A two-state quantum system (a qubit) can carry one bit of classical information. If two bits are not encoded into two qubits separately, but only into their joint properties, entangled states result. It is shown explicitly how quantum teleportation uses this feature and how the randomness of the individual quantum event prohibits instantaneous communication.
