Abstract :
Practical limitations are discussed for the exchange of photonic qubits in optical fibres carrying telecom traffic based on the noise generated by Raman spontaneous scattered photons from the classical signals. It is shown that these limitations are in the co- and counter-propagating directions with respect to the classical channels.
