Abstract
At least one qubit in a quantum computing device is created. At least one photon is placed into a superposition of quantum states. The quantum states each have an associated probability amplitude. The quantum states each are associated with a mode from a group of orthogonal modes. The probability amplitudes associated with the quantum states of the at least one photon are temporally separated thereby forming at least one qubit, the alternative values of which are thus temporally identifiable.
