"Qubit registers have been a hard thing to construct; this looks to be a substantial advance in the multiple entanglements required for their use. Quoting: 'Olivier Pfister, a professor of physics in the University of Virginia's College of Arts & Sciences, has just published findings in the journal Physical Review Letters demonstrating a breakthrough in the creation of massive numbers of entangled qubits, more precisely a multilevel variant thereof called Qmodes. ...
"If the development of a quantum computer were like motor racing, then we would currently be in the twisty-turny bit that comes before we barrel over the mountain and hit the long, fast straightaway. We know the requirements for quantum computing; we even know systems that kinda-sorta meet these requirements. But no existing quantum computing architecture—that is, how we make quantum bits (qubits) and perform operations on them—is really all that satisfying. If you don't even know which materials are best for building a quantum computer, it makes progress awfully slow..."
Some tech enthusiasts grumble and gripe about the [according to their perception] lack of innovation in computing this past decade. While you can argue about the various merits and demerits of Intel's x86 microarchitecture, there is no denying that technology and innovation will move forward in the future. Massive leaps in computing power have taken place in just a few decades.
