报告摘要🧨：
We proposed a SQUID structure formed by a spin-orbit coupling nanowire Josephson junction which contains Majorana fermions, and a conventional superconductor-insulator-superconductor junction. It is shown that the critical current of the SQUID is different for two flowing directions, due to the unconventional current-phase relation of the nanowire junction. We also considered a setup consisting of a 1-d topological superconductor and two quantum dots tunneling connected with each end and show that non-local entanglement between the two quantum dots appears. These novel tunneling effect, if measured experimentally, would be helpful for signal the Majorana fermions in materials.
