Event Details

Quantum science and technology hold the promise to deepen our understanding of the universe and innovate groundbreaking technology. This poses a grand challenge to today’s scientists and engineers, unprecedented in the generations that came before us. Successfully achieving breakthroughs would require an interdisciplinary approach that leverages resources from various disciplines to forge new pathways which cannot be defined by a singular field of study.

In this talk, I will share my interdisciplinary adventure in the quantum material and quantum device that leads me to a wider science and engineering world. I will start from the study of fundamental properties of Dirac and topological materials, how they manifest in Josephson junctions, and what material physics we can leverage to innovate single-photon detectors, measure the quantum state of the photon, and contribute to the search of the axion dark matter. I will also discuss how to utilize the novel properties of the two-dimensional van der Waals materials to miniaturize qubits and develop quantum-noise-limited amplifiers. Finally, I will turn around to apply what we learn from quantum sensing to study the pairing symmetry of novel superconductivities, including the magic-angle-twisted graphene and topological Weyl superconductors. I will elucidate how to harness the kinetic inductance of these novel superconductors for future flight-missions to explore the origin of life and planetary science.
