Research Description
Dafei Jin aims to develop a new platform for exchanging quantum information over distance. His team plans to trap single barium ions atop atomically thin solid helium adsorbed on a nanofabricated device and manipulate their optical transitions as the environment shifts from vacuum to superfluid helium, then to solid helium. The project will also pursue microwave control and optical readout of ions’ internal states, as well as their coupling to superconducting circuits. These experiments could shed light on whether ion qubits on noble-element quantum solids can serve as microwave-optical interfaces and interact with electron qubits on quantum solids.
Research Impact
Professor Jin’s work could advance the use of noble-element quantum solids as ultraclean hosts for quantum technologies across a wide range of frequencies. It could also open a unique path toward distributed quantum information processing. Even intermediate results, such as trapping many ions on quantum solids and measuring their optical transitions, would improve our understanding of how quantum solids can host and connect different kinds of qubits.
