The efficiency of quantum computers is mainly limited by the fidelity of (multi-) qubit gates (in particular non-Clifford gates), inter-connectivity of its qubits, and coherence time. Optimizing these parameters results in limiting the number of usable qubits, which can be leveraged by entangling multiple quantum computers at different locations. To this end, entangled information is transferred between potentially distant systems, which is accomplished by employing quantum frequency converters and quantum routers in concert with standard telecom fibers of the existing internet infrastructure.
