Superconducting and topological quantum computing are two platforms in which information is encoded using entirely different paradigm. When a topological material is coupled to a s-wave superconductor, the supercurrent can be carried by their robust and topologically protected surface/edge channel, which results in exotic excitation that mimics the behavior of Majorana Fermions. In line with the interests to probe such excitations, in this talk, I will introduce a qubit consists of superconducting quantum circuits and topological material. We demonstrate a Josephson junction and a first flux- tunable qubit based on Weyl semimetal.
