Chaining Atoms Together Yields Quantum Storage
02-17-22
Engineers at Caltech have developed an approach for quantum storage that could help pave the way for the development of large-scale optical quantum networks. "The ability to build a technology reproducibly and reliably is key to its success," says graduate student Andrei Ruskuc. "In the scientific context, this let us gain unprecedented insight into microscopic interactions between ytterbium qubits and the vanadium atoms in their environment." The new system relies on nuclear spins—the angular momentum of an atom's nucleus—oscillating collectively as a spin wave. This collective oscillation effectively chains up several atoms to store information. "Based on our previous work, single ytterbium ions were known to be excellent candidates for optical quantum networks, but we needed to link them with additional atoms. We demonstrate that in this work," says Andrei Faraon, Professor of Applied Physics and Electrical Engineering. [Read the paper] [Caltech story]

Nano-Architected Material Resists Impact Better Than Kevlar
06-25-21
Julia R. Greer, Ruben F. and Donna Mettler Professor of Materials Science, Mechanics and Medical Engineering; Fletcher Jones Foundation Director of the Kavli Nanoscience Institute, has developed a nano-architected material made from tiny carbon struts that is, pound for pound, more effective at stopping a projectile than Kevlar, a material commonly used in personal protective gear. "The knowledge from this work could provide design principles for ultra-lightweight impact resistant materials for use in efficient armor materials, protective coatings, and blast-resistant shields desirable in defense and space applications," says Greer.
