New York is betting big on quantum communication.
In September 2025, state and university leaders announced a $300 million investment to turn Long Island’s existing telecom fiber into a quantum testbed. At its center is the State University of New York at Stony Brook’s (SBU) planned Quantum Research and Innovation Hub. The 14,000 m2 facility will host the first data center built to manage entangled photons — the twin particles whose shared state forms the basis of quantum communication — as easily as today’s routers handle digital bits. If successful, the network could underpin ultra-secure communications networks.
“We’ve already built the largest quantum network in the country,” said SBU President Andrea Goldsmith, referring to photon-entanglement experiments between Stony Brook and Brookhaven National Laboratory. “The harder task is proving that entanglement can survive as we grow the network. That’s what research is: taking risks to create technology with real impact on security, the economy and science.”
