We build a system composed of two integrated silicon chips, a transmitter and a receiver, linked by a five-meter long seven-core fibre. Maximally entangled two- and four-dimensional quantum states, prepared and measured over the two chips, are succesfully verified. These results mark a key step towards the development of distributed quantum applications.
