Quantum Memory for Secure Communication

SBIR · Phase: BOTH · Topic DAF26BZ06-NV035 · Solicitation 26.BZ

The rapid advancement of quantum computing poses a significant challenge to traditional encryption methods, potentially compromising the security of digital communications. Quantum Key Distribution (QKD) provides a solution by utilizing quantum properties to generate secure encryption keys. However, the current QKD systems are limited by signal loss over long distances, preventing widespread implementation. This project seeks to address this limitation by developing advanced quantum memory systems, or quantum repeaters, designed to extend the range and fidelity of quantum signals. These repeaters will enable efficient Quantum Key Distribution over long distances, thereby enhancing secure communications for the Air Force's digital infrastructure. The primary goal of this project is to develop and demonstrate advanced quantum memory systems capable of high coherence and minimal loss, essential for reliable communication within quantum networks. At the project start, the technology is at a Technology Readiness Level (TRL) 2, focusing on the application concept formulation. By the end of Phase II, the target is to reach TRL 5, demonstrating the integrated system in a relevant environment. The required efforts will commence with foundational research and development of quantum memory hardware. In Phase I, the tasks will involve designing quantum memory materials, developing quantum repeater prototypes, and validating their performance through controlled laboratory experiments. Key activities will include: ● Designing and fabricating quantum memory materials aimed at reducing signal decoherence and data loss. ● Developing prototypes capable of storing and transmitting photonic qubits. ● Conducting laboratory tests to validate the prototypes' performance against defined metrics (e.g., coherence, loss, noise). For Phase II, the focus will shift to refining these prototypes, integrating them into a scalable network, and validating their operation in a relevant environment. The main activities will include: ● Enhancing quantum memory systems for increased coherence fidelity and extended transmission distances. ● Integrating prototypes with existing entanglement sources and quantum communication networks. ● Testing the quantum memory systems in simulated and real-world environments to ensure robustness and reliability. ● Evaluating performance through rigorous data collection and analysis to meet predefined security and operational metrics. Minimum deliverables for this project include detailed technical reports, functional quantum memory prototypes, performance evaluation data, and an integration roadmap detailing steps for transition into operational use. The advanced quantum repeater systems developed through this SBIR initiative will significantly enhance the DoD's capabilities in secure communications, positioning the Air Force at the forefront of quantum-secured information transfer.
