Rochester Quantum Network (RoQNET)

RoQNET connects the University of Rochester and RIT via an 11-mile fiber-optic quantum communications network using individual photons for secure data transmission

Quantum communication ensures data security by using qubits, which cannot be cloned or intercepted without detection, offering unprecedented protection

Photons, as discrete particles of light, are ideal for long-distance quantum communication due to their compatibility with existing fiber-optic infrastructure

Researchers developed photonic-integrated circuits combining a photonic chip, fiber array unit, and highly nonlinear crystal to produce entangled visible-telecom photon pairs for efficient quantum communication

The project aims to replace bulky superconducting nanowire single-photon detectors (SNSPDs) with portable, scalable technologies to simplify quantum experiments

RoQNET emphasizes distributed quantum entanglement, enabling perfectly correlated quantum particles to interact regardless of distance

RoQNET uses solid-state quantum memory nodes and integrated quantum photonic chips, representing a novel approach to quantum communication

Plans include extending RoQNET to institutions like NYU, Stony Brook University, and Brookhaven National Lab, creating a broader quantum communication network across New York State

The Air Force Research Laboratory supports the project, highlighting its importance for secure communication and national security

RoQNET sets new benchmarks for secure communication protocols, addressing growing concerns about data integrity and privacy
