Detecting nonclassical light is a central requirement for photonics-based quantum technologies. Unrivaled high efficiencies and low dark counts have positioned superconducting nanowire single-photon detectors (SNSPDs) as the leading detector technology integrated photonic applications. However, challenge lies in their integration within circuits, regardless of material platform or surface topography. Here, we introduce method based on transfer printing that overcomes these constraints allows SNSPDs onto arbitrary substrates. With kinetically controlled elastomer stamp, suspended commercially manufactured silicon lithium niobate insulator circuits. Focused ion beam metal deposition then wires to thereby allowing us monitor photon with >7% detection efficiencies. Our eliminates bottlenecks provides new venues versatile, accessible, scalable information processors.
