The experiment, published in Science, brought quantum networking out of the lab, where it has tradi…

Engineers send quantum signals with standard Internet Protocol

In a first-of-its-kind experiment, engineers at the University of Pennsylvania brought quantum networking out of the lab and onto commercial fiber-optic cables using the same Internet Protocol (IP) that powers today's web.

Quantum internet is possible using standard Internet protocol — University engineers send quantum signals over fiber lines without losing entanglement

A recent experiment by University of Pennsylvania researchers found that quantum signals can be sent over standard internet protocol (IP). The research, done on the University's fiber network, uses a locomotive-style approach to pair a traditional light signal "engine" with quantum signal cargo and send quantum signals over the internet without observing the particles.

Engineers Send Quantum Signals With Standard Internet Protocol

An anonymous reader quotes a report from Phys.org: In a first-of-its-kind experiment, engineers at the University of Pennsylvania brought quantum networking out of the lab and onto commercial fiber-optic cables using the same Internet Protocol (IP) that powers today's web. Reported in Science, the work shows that fragile quantum signals can run on the same infrastructure that carries everyday online traffic. The team tested their approach on Ver…
