Description

Research Topic Description, including Problem Statement:

Quantum systems based on solid-state spins, such as the nitrogen-vacancy (NV) centers in diamond, have attracted substantial interest as potential sensor platforms, particularly for magnetometry. These solid-state quantum systems allow measurements tied to fundamental physical constants, in principle producing a calibration and drift-free sensor. Compared to existing alternatives, these quantum sensors can provide a unique combination of state-of-the-art sensitivity; high-bandwidth sensing, and low size, weight, and power (SWaP) requirements. However, improvement of readout fidelity, T2* dephasing time, and sensor initialization efficiency are required for these solid-state spin systems to challenge legacy atomic sensor systems in performance, reliability, and cost. Unlike established legacy sensors such as atomic vapor cells, readout techniques for solid-state spin systems are still in their infancy and typically provide performance far from theoretical limits. Research in this area will focus on assessing current approaches and developing new methods to improve sensor readout fidelity, with an emphasis on techniques well suited for operation in deployed systems outside of a controlled laboratory environment.

Example Approaches:

Research for this topic may include a variety of methods to improve the readout fidelity of these sensors. Non-optical readout approaches, such as the cavity-enhanced microwave readout technique are showing considerable promise.

Relevance to the Intelligence Community:

Navigation in the absence of GPS, especially over featureless terrain like the ocean, is a serious challenge. One way the Department of Defense (DoD) and the Intelligence Community are looking to address this is through magnetic field aided navigation. The earth’s crustal magnetic field is suitable for this purpose because it has significant spatial and negligible temporal variation. We aim to develop a high-sensitivity quantum sensor to measure the vector components of the magnetic field. The envisioned sensor will provide quality data to help map the Earth’s crustal magnetic field globally, to a resolution capable of supporting DoD’s Alternative Positioning and Navigation applications.
