Qubits - 0, 1 Or Both

The power of quantum mechanics for data transmission is intriguing because of potential for secure, high speed communications but current storage and transmission of quantum information is far too fragile to have any practical value in the near term. In classical communications, a bit can represent one of two states - either 0 or 1. But because photons are quantum mechanical objects, they can exist in multiple states at the same time. Photons can also be combined, in a process known as entanglement, to store a bit of quantum information (i.e. a qubit).  read more
