Quantum computing is finally heating up. There is a heady mix of high-profile and highly resourced big tech players like Google, Microsoft, Amazon Web Services, and Nvidia either building QPUs, simulating them, or integrating them with classical supercomputers in addition to well-funded younger companies and startups, such as QuEra, IonQ, Quantum Computing, Quantinuum, D-Wave, and Alice & Bob.
Over the past year or so, many of these companies have made significant advancements in error correction, qubit count and decoherence, scale, and quantum advantage, that latter bit being the stage when a quantum computer can solve a problem that would be impossible for a classical computer to do or, more practically, one that would take the classical computer many years to complete and therefore makes the approach impractical.
Standing squarely among all of these quantum companies is IBM, the venerable 114-year-old tech giant that has been working on the quantum computing challenge for…
