Claim 13:
14. The method as claimed in claim 13, wherein, in said second step, said encoder (3) is supplied with said two subsequences of N electrical signals in order for it to generate, from each pair (i) of electrical signals xi and yi, a photon having a first quantum state corresponding either to said first quantum information unit |0 corresponding to a phase difference of 0 in the presence of two electrical signals xi=0 and yi=0, or to the second quantum information unit |1 corresponding to a phase difference of π in the presence of two electrical signals xi=0 and yi=1, or a uniform superimposition of said first |0 and second |1 quantum information units corresponding to a phase difference of π/2 in the presence of two electrical signals xi=1 and yi=0, or even to another uniform superimposition of said first |0 and second |1 quantum information units corresponding to a phase difference of −π/2 in the presence of two electrical signals xi=1 and yi=1.
