New kind of quantum transport discovered in a device combining high-temperature superconductors and graphene

https://phys.org/news/2023-04-kind-quantum-device-combining-high-temperature.html 

"graphene's Klein tunneling and superconductor's Andreev reflection (hybrid Andreev-Klein electronic transport)... do not consume much power. Conventional superconductors are key materials in a variety of quantum devices, and are especially important in one strategy to build both qubit and topological quantum computers. By combining the two, the study's results can open new fundamental physics in these materials and ultimately establish a whole new platform for quantum technology devices"
