Completed TRL 3 (started at 2, targeting 3)
The world of quantum mechanics offers new mechanisms for communication, computation, and sensing. Quantum networks enable the transmission of quantum information over long distances by first distributing entanglement across many quantum repeaters, and then using this entanglement as a resource for state teleportation. Reports of the first memory-based quantum repeater node that beats direct photon transmission between two points has set the stage for the development of a quantum internet of connected quantum repeaters, computers, and sensors.
High speed, long range transfer of quantum information can be achieved by multiplexing many memory-assisted quantum repeater nodes. With their efficient spin-photon interfaces and long coherence times, atomic defect qubits in diamond have become the leading solid state platform for this application. My research seeks to develop an all-in-one platform for electronic and photonic control of atomic memories in diamond. By integrating hundreds of quantum memories on one chip, I will enable scalable production of quantum repeater nodes with individually-manipulable qubits. These quantum repeater nodes can be joined into a quantum network capable of interconnecting ground stations, spacecraft, and satellites, with implications for precision navigation and timing, secure data transfer, and distributed computing. Moreover, quantum networks can be used to drastically extend the baseline for large-aperture astronomical interferometry, enabling higher imaging resolution than ever before.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
