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).
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.
The RadioBio program aims to establish whether functional signaling via electromagnetic waves between biological cells exists and, if it does, to determine what mechanisms are involved and what information is being transferred. The program seeks to determine the validity of electromagnetic biosignaling claims and, where evidence exists, understand how the structure and function of these natural “antennas” are capable of generating and receiving information in a noisy, cluttered electromagnetic environment.
The Space Environment Exploitation (SEE) program seeks to develop new models and sensing modalities to predict and observe the dynamics of the near-earth space environment. The SEE program explores how to go beyond magnetohydrodynamic descriptions of the magnetosphere, ionosphere, thermosphere coupled system to include wave/wave, wave/particle, and particle/particle interactions while using the latest advances in high performance computing such as GPUs and TPUs.
For decades, miniaturizing electronics has been key to a wide array of technology innovations and an important economic driver. As an example, the seemingly endless shrinking of the transistor has allowed the semiconductor industry to place ever more devices on the same amount of silicon. Each time the size decreased, transistors became faster and used less power, allowing increasingly capable electronics in smaller packages at reduced cost.
