quantum communication

For the first time, a quantum computer has been operated in space, marking a milestone in the effort to take quantum computing beyond Earth. Scientists say the demonstration opens the path to space-based quantum processing, which could eventually support secure communications and Earth observation. The achievement is drawing wide attention as a proof of concept for future quantum technologies in orbit.

UCLA has received $75 million in grants from the National Science Foundation to advance quantum technology research. The funding will support the university's work in quantum science, a field seen as key to future computing, sensing and communications. The announcement highlights growing federal investment in quantum research at American universities.

A quantum communication link has been shown operating over fiber optic cable already carrying 400G Ethernet and 5G traffic, demonstrating that quantum networking can coexist with conventional high-capacity telecommunications on deployed infrastructure rather than requiring dedicated lines. This points to a cheaper path for integrating quantum-secure communications into existing networks.
