Transient quantum effects in quantum dots linked by topological superconductor

This paper investigates temporary quantum effects occurring when two quantum dots are connected on opposite sides of a topological superconductor nanowire hosting boundary Majorana modes. Specifically, it looks at non-equilibrium electron pairing transmitted between the dots via the Majorana zero energy modes in the transient period after the system is first connected. It finds signatures of nonlocal electron pairing effects that subsequently disappear as the system evolves to its steady state configuration. The duration of these temporary nonlocal effects is estimated and their potential role in quantum computing applications involving braiding of topological qubits is discussed.
