This project investigates how spins precess on short timescales before reaching steady state, a regime that remains poorly understood yet critical for quantum technologies. Current knowledge of spin dynamics largely focuses on steady states, but many quantum applications require operations within hundreds of nanoseconds—before stabilization occurs. Exploring this transient regime could reveal new phenomena enabling fast, low-latency quantum operations.

The research aligns with the rapidly growing field of quantum magnonics, which leverages magnons—quanta of collective spin excitations—for quantum information processing. Recent breakthroughs, such as single-magnon detection via superconducting qubits, highlight the potential of hybrid quantum systems for sensing and communication. Magnon-photon coupling, in particular, offers a pathway to microwave-to-optical conversion, a key step toward building a quantum internet.

Methodologically, the project draws inspiration from pulse-shaping techniques used in semiconductor spin systems to achieve controlled state transitions. It will explore nonlinear dynamics induced by high-amplitude excitations in magnonic systems—an area largely unexplored but essential for developing quantum spintronic interfaces.

Impact: Understanding and controlling short-timescale spin dynamics could unlock new functionalities for quantum computing, sensing, and communication, bridging a critical gap toward scalable quantum technologies.
