Title: Mathematical modelling of molecular and atomic qudits for efficient gate implementations
Abstract: This presentation bridges the fields of quantum chemistry, atomic physics, and quantum computing by exploring qudits—quantum systems with more than two levels—and their uses in quantum information processing. The benefits of qudits, such as their ability to handle more complex computations with fewer gates, are discussed alongside challenges like increased vulnerability to errors (decoherence) and strategies to overcome them. Key topics include modeling qudits implemented in atomistic or atomistically-adjacent platforms, particularly focusing on the electrically-driven lanthanide hyperfine levels in the Terbium Bisphthalocyanine Single Molecule Magnet, and designing quantum gates using techniques like Givens QR Decomposition and GRAPE. The presentation also touches on cutting-edge methods, such as Physics-Informed Neural Networks, and strategies for optimizing gates to enhance robustness against noise. Whether new to quantum computing or looking to deepen understanding, this presentation aims to provide a comprehensive guide to modeling and optimizing qudit quantum systems.
