Quantum Ccomputing Hits Growing Pains

Quantum computing at the edge offers immense compute capabilities for Internet of Things devices, particularly at the edge. But make no mistake: quantum is still in transition. The future of edge computing and the Internet of Things (IoT) may be shaped in part by what happens now at the edge of the atmosphere. In late 2019, an “ultra-precise quantum sensor” was delivered to the International Space Station as part of a core subsystem for the Jet Propulsion Laboratory’s Cold Atom Laboratory (CAL). In January 2021, Chinese scientists said they had created the “first integrated quantum communication network” that combined optical fibers on the ground with two ground-to-satellite links to achieve quantum key distribution over a total distance of 4,600 kilometers. The quantum sensor used to measure gravity at the space station was the...
