Researchers from CnrNano and University of Geona have discovered that the Sauter-Schwinger effect could finally be realised in a regular low-temperature superconducting material. The research appears as the cover story on the journal Physical Review Letters.

The just launched SuperGate project aims at creating an interface between superconductors and semiconductors. It is based on a path-breaking discovery by CnrNano’s research team.

A classical battery converts chemical energy into a voltage bias that can power electronic circuits. Similarly, a phase battery is a quantum device that provides a persistent phase bias to the wave function of a quantum circuit. This key element for quantum technologies based on phase coherence as been demonstrated by Francesco Giazotto’s groupand published in Nature Nanotechnology.
