Founder Professor Axel Hoffmann, working with researchers from Argonne National Laboratory and the Korea Advanced Institute of Science and Technology, has demonstrated a significant advancement in magnon-based information processing technology. The team successfully showed how magnon pulses — collective excitations of spins in magnetic materials — can create controllable interference patterns similar to light waves, opening new pathways for quantum computing applications.
Key Details
- Successfully connected two yttrium iron garnet (YIG) spheres through a superconducting resonator.
- Demonstrated coherent energy transfer between the spheres using microwave pulse excitation.
- Created controllable constructive and destructive interference patterns by manipulating pulse timing.
- Established foundation for complex magnonic networks that could perform advanced information processing.
"What makes this research so exciting is that we're demonstrating magnons can maintain quantum coherence across physically separated materials. This is a critical step toward harnessing spin-based systems for quantum information processing," explained Hoffmann.
This breakthrough establishes the foundation for developing more complex magnonic networks capable of performing advanced information processing tasks.
