Abstract: On the right wavelength Quantum communication with photonic quantum bits (qubits) could be conveniently achieved using telecom optical fibres, but the memory and processing elements of a quantum network — typically alkaline atoms — operate at shorter wavelengths. Tanzilli et al. now report the development of an interface that enables qubits to be transferred between these different wavelengths, while preserving their essential quantum properties. Such an interface could prove useful in quantum information networks based on stationary atomic memories and travelling photonic qubits.
