Quantum computing (QC) and quantum networking (QN) are related, though independent, industries. Both leverage the same unexplained phenomenon in quantum physics: the entanglement between particles that enables them to share states — or in the digital sense, information — in apparent violation of relativity theory. But as services, they fulfill separate functions. QC endeavors to solve problems typically delegated to supercomputers, or that would be so delegated if supercomputers were fast enough to resolve those problems within our lifetimes. QN would secure connections between digital devices (including the conventional variety — yours and mine) using a physics technique that would be permanently crack-proof. It would rather let the connection crash than allow it to be pilfered. In a previous Status Report published in March , I came down hard on quantum computing as a viable technology. I had just taken part in a virtual quantum conference where QC and QN were both featured on the same stage. And I came away with a single, conglomerate viewpoint about the two endeavors. If you read my ZDNet colleague Daphne Prince-Ringuet’s thorough, up-to-date coverage , you might wonder from whence my negative attitude about QC sprang forth (not quite iambic pentameter, but I… Read full this story
