Satellites may enable better quantum networks
The micro-ring resonator, shown here as a closed loop, generated high-dimensional photon pairs. Researchers examined these photons by manipulating the phases of different frequencies, or colors, of light and mixing frequencies, as shown by the crisscrossed multicolor lines.

Quantum Communications and Networking Group

The Quantum Communications and Networking Group exploits quantum phenomena for transformative capabilities in communications and quantum technology. Our work seeks to dramatically improve the cybersecurity of the nation’s critical infrastructure with the development and demonstration of quantum key distribution technologies.  In addition, we are developing the fundamental building blocks for realizing quantum sensor networks, quantum repeaters and ultimately, a future quantum internet.
