Anyone for Anyons?

Researchers have demonstrated that a strange type of quantum particle called the anyon, believed to exist in only two dimensions, can also be created in one

Applications of Quantum Information

Ongoing
Human-scale physical phenomenon represent the emergent, complex behavior of simple, microscopic laws. In the past twenty years, improved understanding of these microscopic laws have suggested that typical large-scale systems — those used in modern day technology from transistors to mechanical

Light-matter interactions in Semiconductor Nanostructures

Ongoing
We investigate the interaction of light with semiconductor-based nanostructures. We extend concepts of entanglement and coherence in atomic physics to our solid-state systems. Our devices are based on semiconductors, like GaAs. We use InAs quantum dots (QDs) in GaAs as artificial atoms; they have
rare earth ions in a host crystal

Memory

Ongoing
While photonic systems offer very robust qbits and are excellent for transporting quantum information between locations due to their minimal interactions with their environment, they are inconvenient for the storage of quantum information in one place. As a result there is significant interest in
