The technique can also detect polaritons\u2014hybrid light\u2013matter excitations that may be useful in quantum technologies\u2014with higher resolution than earlier methods. The researchers expect the new technique to be useful in fields as diverse as quantum information and nanophotonics.<\/p>\n<p>When a superconductor held just below its critical temperature absorbs a single photon, the superconductivity can be destroyed in a small region of the material, triggering a small electrical signal. Recent advances have expanded the operating temperatures of such detectors and improved their sensitivities to photons over a wide range of frequencies, enabling many new applications. Mengkun Liu of Stony Brook University in New York and colleagues wondered if the same sensitivity might be employed to build high-resolution spatial maps of the properties of superconducting samples. \u201cSpatial variations often influence superconducting strength and coherence, so an ability to image these properties locally would bring valuable insight,\u201d says Stony Brook team member Ran Jing.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>An imaging method provides unprecedented resolution for studies of quantum materials by relying on superconductors\u2019 extreme sensitivity to light.
