The quantum entanglement of particles, such as photons, is a prerequisite for the new and future technologies of quantum computing, telecommunications, and cyber security. Real-world applications that ...

Engineers from Università degli Studi di Pavia have created a micro-ring that entangles individual particles of light. The design is based on a micro ring resonator, a loop etched onto a silicon wafer ...

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 ...
