Dissipationless nonlinearities for three-wave mixing are a key component ofmany superconducting quantum devices, such as amplifiers and bosonic qubits. Sofar, such third-order nonlinearities have been primarily achieved with circuitsof concatenated Josephson tunnel junctions. In this work, we theoreticallydevelop an alternative approach to realize third-order nonlinearities fromgate-tunable and intrinsically symmetry-broken quantum material Josephsonjunctions. We illustrate this approach on two examples, an Andreevinterferometer and a magnetic Josephson junction. Our results show that bothsetups enable Kerr-free three-wave mixing for a broad range of frequencies, anattribute that is highly desirable for amplifier applications. Moreover, wealso find that the magnetic junction constitutes a paradigmatic example forthree-wave mixing in a minimal single-junction device without the need for anyexternal biases. We hope that our work will guide the search of dissipationlessnonlinearities in quantum material superconducting devices and inspire new waysof characterizing symmetry-breaking in quantum materials with microwavetechniques.
