Quantum information science relies on the isolation and control of complex, many-body configurations of quantum-mechanical states. Electronic and nuclear spins in solid-state materials are natural building blocks for quantum technologies, whether as memory or processing elements (qubits), transducers of classical fields (sensors), or coherent interfaces for quantum fields (e.g., as light-matter interfaces or magnonic quantum buses). Materials and device design principles that enable these quantum applications also underlie recent advances in efficient classical information technologies such as magnetic memory and spin logic. Quantum-coherent spin phenomena occur in various materials spanning semiconductors, metals, and insulators, and in morphologies spanning bulk three-dimensional crystals, two-dimensional sheets, optoelectronic devices and heterostructures, down to individual molecules. In all these materials, spins interact in complex ways with photons, phonons, and charge carriers, and they can be controlled using external fields in nanoscale devices amenable to realizing new technologies at scale. Improvements in materials synthesis, theory, computation, fabrication, and measurement techniques will facilitate the realization of increasingly complex heterostructure materials, devices, and experimental protocols that use spins to store, manipulate, and transduce quantum or classical information.

This symposium will bring together scientists researching spin dynamics across these diverse materials platforms, with an emphasis on emerging materials, new experimental and theoretical techniques, and cross-cutting device concepts that enable the control of spin dynamics for rapidly evolving information technologies.
