“It would be tempting to conclude from all this that the basic problems are solved in principle and the path to a future of ubiquitous quantum computing is now just a matter of engineering. But that would be a mistake. The fundamental physics of quantum computing is far from solved and can’t be readily disentangled from its implementation.”

Very cool! related to the lens array concept that we have pioneered in CAP-MIMO! However, this approach is not true beamspace spatial reuse since different beams correspond to different frequencies via an array waveguide (as in optical fiber) – so room for improvement!

These optical fibers connect to a lens, which can be mounted to a ceiling to create an optical wireless network.
