Control of quantum properties of Andreev bound states in bilayer graphene-based Josephson junctions using gate voltage

https://phys.org/news/2024-07-method-quantum-bound-states-superconducting.html

"We have observed the Andreev bound states in the long Josephson junction limit, a phenomenon predominantly seen in the short Josephson junction limit. We anticipate that the number of energy levels can be readily adjusted by applying gate voltage alone, offering potential applications in diverse fields such as quantum computing and high-precision quantum sensors"
