Description

We study non-local entanglement in a supercurrent of electrons split from and recombined into Cooper pairs using a parallel double quantum dot Josephson junction. While tuning independently the chemical potential of the QDs with local electrical gates the non-local transport is confirmed through study of the non-dissipative current as the Josephson current arises only from processes which maintain the coherence.
