Department of Energy to develop a low noise superconducting Quantum Interference Device (SQUID)-based amplifier chip for high speed applications. SQUIDs, or superconducting quantum interference devices, are extremely sensitive, ring-shaped detectors of magnetic fields. The most sensitive of commercially-available magnetometers, called Superconducting Quantum Interference Devices (SQUIDs) can measure extremely small magnetic fields, such as the flux or force of magnetism on a single human red blood cell with a diameter about 7 microns. |
