"Interfacing Quantum Information and Quantum Sensing "

Charlotte Boettcher , Yale
[Host: Despina Louca]

Quantum information is a rapidly growing field that continues to develop and explore a variety of platforms to realize scalable quantum devices. Progress in qubit technology is driven by continued advancement in materials research, which informs fundamental issues such as the underlying mechanisms limiting qubit coherence times. Further, quantum materials including superconductors, magnets, insulators, and topological materials all offer unique properties that can be implemented into quantum circuits to realize new functionalities. In this way, the fundamental physics of quantum materials is intertwined with the development of next-generation quantum devices.
In this talk, I will discuss several topics at the intersection of quantum information and quantum materials research, which demonstrate this symbiotic relationship between the two fields. This includes how one can use Josephson junctions - a critical element of the Transmon qubit - formed into arrays to serve as both a quantum simulator of interacting many-body systems such as the Hubbard model as well as a novel platform to study quantum phase transitions such as the superconductor-to-insulator transition. Additionally, I will discuss how microwave circuits can be used as a sensitive probe of the order parameter symmetry in low-dimensional unconventional superconductors and mesoscopic heterostructures, as well as for a variety of other quantum sensing applications. Finally, I will discuss future opportunities to leverage the interplay between quantum materials and quantum information to both gain insight into enigmatic phases of matter and design novel qubits and quantum devices.
