Disentangling the Facts from the Hype of Quantum Computing

Few fields invite as much unbridled hype as quantum computing. Most people’s understanding of quantum physics extends to the fact that it is unpredictable, powerful, and almost existentially strange. A few years ago, I provided IEEE Spectrum an update on the state of quantum computing and looked at both the positive and negative claims across the industry. And just as back in 2019, I remain enthusiastically optimistic today. Even though the hype is real and has outpaced the actual results, much has been accomplished over the past few years.
