Currently, superconducting qubits lead the way in potential candidates for quantum computing. At the same time, transferring quantum information over long distances typically relies on the use of photons as the elementary qubit. Converting between stationary electronic qubits in superconducting systems and traveling photonic qubits is a challenging yet necessary goal for the interface of quantum computing and communication. One promising path to achieving this goal appears to be the integration of superconductivity with optically active semiconductors, with quantum information being transferred between the two by means of the superconducting proximity effect. Obtaining good interfaces between superconductors and semiconductors is the next obvious step for improving these hybrid systems. Here, we report on our observation of superconductivity in a 2.3 μm diameter self-assembled indium structure grown epitaxially on the surface of a semiconductor material.
