  Weyl semimetals for their exotic topological properties have drawn
considerable attention in many research fields. When in combination with s-wave
superconductors, the supercurrent can be carried by their topological surface
channels, forming junctions mimic the behavior of Majorana bound states. Here,
we present a transmon-like superconducting quantum intereference device (SQUID)
consists of lateral junctions made of Weyl semimetal Td-MoTe2 and
superconducting leads niobium nitride (NbN). The SQUID is coupled to a readout
cavity made of molybdenum rhenium (MoRe), whose response at high power reveal
the existence of the constituting Josephson junctions (JJs). The loop geometry
of the circuit allows the resonant frequency of the readout cavity to be tuned
by the magnetic flux. We demonstrate a JJ made of MoTe2 and a flux-tunable
transmon-like circuit based on Weyl materials. Our study provides a platform to
utilize topological materials in SQUID-based quantum circuits for potential
applications in quantum information processing.
