Superconductors serve as a key platform for quantum computing, sensing and communicating technologies. As opposed to semiconductors, superconducting devices operate on magnetic fields and not on electric voltage, imposing a strong restriction on device miniaturization. Another major challenge is imposed by the strict requirements for ambient temperature and substrate lattice matching for superconducting film growth, limiting device integration. By growing amorphous superconductors and processing quantum devices on a large variety of substrates (Si chips, polymer films, van der Waals layered materials, glass and ferroelectrics), we demonstrated that the functional properties of these materials are substrate independent. Moreover, using a flexible substrate we demonstrated flexible magnetic and quantum superconductive devices. Finally, we revealed under expected tunability of superconducting quantum interference devices (SQUIDs) by means of mechanical flexure, paving the way for device miniaturization.
