The Quantum Internet Is Coming Online

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 centre 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," says SBU President Andrea Goldsmith, referring to photon-entanglement experiments between Stony Brook and Brookhaven National Laboratory (BNL). "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."
