May 6, 2026: White paper submission deadline via link above Topic 1: Quantum Sensors and Quantum Clocks for Position, Navigation, and Timing (PNT) Topic Objective: The objective of this topic is to advance and develop quantum sensor and quantum clock technologies that support non-GPS position, navigation, and timing (PNT) capabilities. Topic Description: The Army is seeking innovative quantum sensors and quantum clocks to supplement existing GPS systems and provide alternative PNT functionality in the event of GPS failure or non-availability: 1. Quantum sensors (e.g., inertial, magnetic, etc.) that enable accurate positioning information for ground vehicles, aircraft, and munitions navigation without requiring GPS. 2. Quantum clocks that provide precise time references, improve time-difference-of-arrival (TDOA) calculations, and enable reliable, non-GPS PNT solutions. Topic 2: Quantum Radio Frequency Sensors Topic Objective: The objective of this topic is to advance the development of quantum sensor technologies that can provide field-demonstrable alternatives to existing radio frequency (RF) antenna systems. Topic Description: The Army is seeking novel radio frequency (RF) sensors leveraging quantum mechanics that provide wider access to the RF spectrum, more sensitive reception of signals, and greater flexibility in the size, weight and power (SWaP) compared to existing Army radio frequency (RF) systems. This topic intends to further develop these sensors with a focus on ruggedization (hardening for temperature and environmental conditions such as weather, dust, etc.) and miniaturization. Key application areas include: 1. Ultra-wideband RF sensing, with the ability to cover exceedingly large frequency ranges (ELF-EHF) from a single antenna aperture without the need to change hardware. 2. Ultra-sensitive RF sensing, with the ability to pull signals out of the noise floor of a loud RF environment or increase the range of detection of signals. Topic 3: Quantum Electromagnetic Sensors Topic Objective: The objective of this topic is to advance the development of quantum sensor technologies with a narrower frequency range for detection of low power, non-RF electromagnetic fields. Topic Description: The Army is seeking quantum electromagnetic sensors outside of the radio frequency range that can augment use cases with narrower frequency ranges. 1. Detection of low power static fields: a. Field sensors that can detect minute environmental anomalies, such as magnetic or gravitational disturbances, to identify subsurface, terrestrial, air and space vehicles (e.g., stealth aircraft, submersibles, etc.). Small, light, and low-power systems are preferable to enable sensors to be located on both aerial platforms (e.g., Group 1 and 2 UAS, High Altitude Balloon Systems, etc.) and ground platforms (e.g., vehicles, robots, etc.). b. Field sensors that can detect minute environmental anomalies, such as magnetic or gravitational disturbances, to identify hidden underground bunkers, tunnels, or resource caches. Small, light, and low-power systems are preferable to enable sensors to be located on both aerial platforms (e.g., Group 1 and 2 UAS, High Altitude Balloon Systems, etc.) and ground platforms (e.g., vehicles, robots, etc.). 2. Detection of bioelectric activity in the human body: Small form factor electric field sensors that can measure electrical signals in the human body (e.g., electroencephalograms and electrocardiograms) accurately and quickly to augment field medicine. Topic 4: Photonics Topic Objective: The objective of this topic is to advance and develop innovative technologies that leverage photonics for secure, high-speed communication and data processing. Topic Description: The Army is seeking advanced and scalable photonics components and systems to enhance mission-critical capabilities in communication and edge processing. Key application areas include: 1. Secure, High-Bandwidth Communications: a. High-speed optical electronics for rapid, high-volume data transfer. b. Secure and resilient data links between assets (air-to-ground, ship-to-shore). Functionality through smoke, camouflage, and all weather is preferable, as well as resilience to electronic warfare attacks (e.g., jamming, interception). Data link range should reflect the targeted platform (e.g., 35km or less for Group 1 and 2 UAS, 1,000+km for high altitude platforms and jets, etc.). c. High-bandwidth line-of-sight communications for transferring large files. Functionality through smoke, camouflage, and all weather is preferable, as well as resilience to electronic warfare attacks (e.g., jamming, interception). Multiple applications are of interest: i. Transferring data from the edge to Battalion and Brigade headquarters at a range of 2-35km. ii. Transferring data from brigade headquarters to Echelons above Corps at a range of 1,000+ km. iii. Transferring data from on-the-move robots, vehicles, or aircraft traversing the battlefield to fixed sites at a range of 1,000+ km. 2. Edge Processing & Computing: a. Photonic components or integrated circuits optimized for real-time, onboard analysis of sensor data at the point of collection, such as object recognition from hyperspectral video feeds and pre-processing of data on unmanned platforms. Applications of interest span multiple data types, from small microsensor outputs to large full motion video feeds. b. Photonic components that replace conventional RF electronics (e.g., in voice and data radios, SATCOM, RADAR) to reduce size, weight, and power (SWaP) while increasing resilience and performance.
