Programmable Systems with Non-Hermitian Quantum Dynamics
Abstract
Recent years have witnessed a search for new materials and systems capable of displaying novel properties and functions not typically found in nature. This search has been fueled by new concepts such as parity-time (PT) symmetry and non-Hermitian spectral degeneracies known as exceptional points (EPs). Although these notions were initially conceived within the context of quantum field theories, they have been pursued almost exclusively in classical settings with tailored gain and loss profiles. Using these strategies to establish EPs and PT-symmetry in the quantum domain is challenging because the intrinsic quantum noise associated with gain and loss tends to suppress desirable quantum features like entanglement and superposition. This MURI project will develop theoretical and experimental methodologies to introduce and harness non-Hermiticity in quantum materials, optics, sensing and information in a way that preserves quantum coherence, while introducing new functionalities that are unique to non-Hermitian systems. An interdisciplinary team of PIs who have pioneered research in classical and quantum aspects of non-Hermitian dynamics and quantum control will pursue a set of closely-interlinked experimental and theoretical goals by using photonic, superconducting and optomechanical quantum systems to reveal paradigm-shifting possibilities that result from extending EPs to quantum dynamics.
