A large team of researchers with members from MIT, IBM, NASA's JPL and Columbia University has developed a process that that enables scalable integration of superconducting nanowire single-photon detectors (SNSPDs) on a range of photonic circuits. In their paper published in the journal Nature Communications, the team describes their new process and why they believe it may lead one day to a practical photonic quantum processor on a chip.
