AFRL/RITQ - Integrated Photonics and Photon Qubits

FROM THE ULTRAVIOLET TO THE INFRARED

The mission of the AFRL's Quantum Information Processing Group is to generate, manipulate/process, distribute and analyze quantum entanglement both locally and distributed over processing nodes in a quantum network consisting of photon-based and memory-based quantum bits.

As elementary quantum states of light, photons are natural long distance carriers of quantum information and the ideal qubit for fast processing. We generate photon states both in bulk and in chip-scale integrated photonic circuits, with the emphasis moving towards integration as the scaling and complexity of these circuits increase.

Exploiting the large innate entanglement contained within photon’s degrees of freedom will support the implementation of information processing and network functionalities that are fundamentally different from current technology. This work is complemented by the AFRL Quantum Algorithm Group to enact quantum protocols on the circuitry.

We have labs on AFRL's RI campus and in the Innovare Advancement Center.
