Detectors long used to look at the cosmos are now part of X-ray experiments here on Earth. Modern cosmology experiments--such as the BICEP instruments and the Keck Array in Antarctica--rely on superconducting photon detectors to capture signals from the early universe. These detectors, called transition edge sensors, are kept at temperatures near absolute zero, at only tenths of a Kelvin. At this temperature, the "transition" between superconducting and normal states, the sensors function like a...
