Original Abstract Submitted
a method of performing quantum key distribution can include quantum transmission in a first basis state and in a second basis state being non-orthogonal to the first basis state, from a quantum transmission apparatus to a quantum receiving apparatus over two pairs of optical channels, wherein transmitting in the first basis state includes, at a first time slot, transmitting a photon over a first channel of the first pair and transmitting no photon over a second channel of the first pair, and, at a subsequent time slot, transmitting a photon over the first channel of the first pair, and transmitting a photon over the second channel of the first pair, wherein transmission in the second basis state includes transmitting a first portion of a probability distribution of a photon from the quantum transmission apparatus to the quantum receiving apparatus; and transmitting a second portion of a probability distribution of the photon from the quantum transmission apparatus to the quantum receiving apparatus.
