Crossed Andreev reflection and elastic co-tunneling in a three-site Kitaev chain nanowire device
Alberto Bordin, Xiang Li, David van Driel +7
The formation of a topological superconducting phase in a quantum-dot-based Kitaev chain requires nearest neighbor crossed Andreev reflection and elastic co-tunneling. Here we repo…
