Strategic Objectives
• Understand the light-matter interfaces that freeze information in time.
• Explore the physics of EIT, gradient echo, and atomic frequency combs.
• Discover how quantum repeaters extend the reach of the future internet.
• Master the materials science behind long-term stationary qubit storage.
The Core Challenge
The greatest hurdle in the quantum revolution isn't speed, but stillness: the ability to store fragile qubits without decoherence.
