The Quantum Orbital Resonance Spectroscopy (QORS) program will lay the scientific foundation for novel neurodiagnostic capabilities by combining recent advances in quantum photonics with Magnetic Resonance Imaging and Spectroscopy (MRI/MRS). QORS seeks to measure changes in neurochemical concentrations—seen in a range of neurological conditions injuries—without the large, super-conducting magnet used in traditional MRI and MRS, thus leading to the development of a noninvasive, compact neurodiagnostic for assessing traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD).
Based on current quantum mechanical models, the energy density of the quantum vacuum is predicted to be high. Recent advances in fabricating material nanostructures and cavities have fueled the study of vacuum fluctuation-driven phenomena, indicating that the energy density can be modified locally.
The Department of Defense requires secure communications, but the broad availability of advanced communications technology possessed by adversaries makes it increasingly difficult to ensure the integrity and confidentiality of DoD information. The science of quantum communications—in which single photons from entangled photon pairs are transmitted over a distance—offers the possibility of unconditionally secure communication because the act of measuring a quantum object changes it. For quantum communications to be practical, however, several technological barriers must be overcome.
