“Superconducting devices such as SQUIDS (Superconducting Quantum Interferometry Device) can perform ultra-sensitive measurements of magnetic fields. Leiden physicsts invented a method to 3D-print these and other superconducting devices in minutes.
‘Fabricating superconducting devices on a computer chip is a multi-step and demanding procedure, requiring dedicated facilities’, says Kaveh Lahabi, a physicist at Leiden Universty. ‘It usually takes days to complete’,
Lahabi and co-authors have developed a new approach, in which Josephson junctions, essential parts of SQUIDS, can be printed on almost any surface in mere minutes, within an electron microscope.”
