Propagating entanglement
When we think of the transport of quantum information from one place to another, we usually think of electromagnetic radiation (photons). But there are many other types of particles known to quantum physics, and these also could be interesting alternatives to photons for the transport quantum information over short distances. These alternative approaches might be especially important within a quantum information processing device, in particular when individual elements are too closely spaced to be addressed by light (as is the case in many solid-state implementations). We are especially interested in situations where the "vacuum" of free space would be replaced by other sorts of medium, such as one might encounter inside a solid material being used for quantum Information processing.

Formation of a Bose-Einstein Condensate from many overlapping atoms. The uses of this kind of state for creating or propagatin entanglement is one of the situations that will be investigated in this project.
