Talk Title: Safe Autonomous Systems through Neurosymbolic Reasoning
Abstract: Huge strides have made in the widespread adoption of autonomous and human-in-the-loop cyber-physical systems (CPS), partly fueled by dramatic improvements in learning-based techniques. An important aspect of many such CPS applications is that they are safety-critical; any undesirable behavior by such systems can cause serious harm to human lives or property. The formal methods community has been an advocate of using logic and automata as specifications for safety-critical CPSs, and the past few decades have seen significant strides in algorithms for their verification, testing, and automated synthesis. A new challenge now is the presence of learning-enabled components (LECs) in CPSs. In this talk, we will review some recent work on using logic and learning-based techniques to provide guarantees for CPS applications using LECs. Such techniques are neurosymbolic in nature; they rely on infusing symbolic knowledge in neural network-based learning algorithms, as well as using symbolic techniques to reason about such neural systems. We will discuss the applicability and scalability of these techniques to real-world systems, discussing some success stories, as well as lay out some of the challenge problems that would need to be solved.

Talk Title: A chiral light-matter interface with superconducting qubits
Series: Quantum Science & Technology Seminar Series
Abstract: Noise Improving qubit connectivity in quantum networks is crucial for distributed information processing, and for reducing resource overheads in certain error correction protocols. While superconducting circuits have shown great promise for large-scale quantum processors, controlling the flow of light in complex qubit networks has remained a challenge. In this talk, I will discuss our recent work on realizing nonreciprocal light-matter interactions in the microwave domain using a transmon qubit strongly coupled to a 1D waveguide. By modulating the atom-waveguide coupling using magnetic fields, we gain control over the direction of photon emission from the qubit, with the ratio of forward-to-backward coupling rates exceeding 100. I will discuss applications of this platform, including photon-mediated gates between distant qubits and the preparation of many-body dark states in chiral atom arrays. In the second part, I will discuss our exploratory work on using disordered superconducting materials for nonlinear devices suitable for quantum links operating in the millimeter-wave frequency regime. Work based on: Phys. Rev. X 13, 021039 (2023), Phys. Rev. Applied 18, 064088 (2022)
