Quantum Information Technology: Entanglement, Teleportation, and Memory
Abstract
A team of researchers from the Massachusetts Institute of Technology and Northwestern University worked to develop the technology elements needed to perform long-distance, high-fidelity qubit teleportation. In particular: this team developed novel sources of polarization-entangled photons based on chi-2 and chi-3 materials; it developed devices for high-efficiency quantum state frequency conversion and demonstrated long-distance entanglement distribution via optical fiber; and it worked toward realizing quantum memory elements in both trapped-atom and atomic-ensemble systems. The experimental work was supported by a variety of theoretical studies. Other theoretical work addressed more general issues in quantum communication and entanglement applications.
