Project Grant 2608182

Louisiana State University received a $194,596 Exploratory Research Project Grant from the National Science Foundation's Division of Information and Intelligent Systems under the Computer and Information Science and Engineering program (CFDA 47.070), awarded July 1, 2026, for completion by June 30, 2028. The project develops an adaptive protocol to enhance superdense coding reliability in noisy quantum networks by combining quantum error correction with pair-preserving adaptive purification—a resource-efficient approach that improves quantum state quality without discarding quantum pairs. The research evaluates whether information entropy-based metrics, including quantum discord and entanglement of formation, provide superior noise indicators compared to fidelity alone, designs low-overhead estimation methods and real-time tunable purification circuits, and integrates findings with a five-qubit quantum error correction code to quantify effects on throughput, latency, and fidelity.

The deliverables include open-source simulation software and educational materials to support reproducible research and workforce development in quantum communications. The project addresses national priorities in secure communication, advanced computing, and emerging quantum technologies, with direct applications to secure satellite communication, distributed quantum computing, critical infrastructure protection, and future cybersecurity initiatives. By enabling more efficient quantum resource utilization, the work supports the scalability of quantum communication systems for next-generation quantum internet infrastructure.
