One of Japan’s leading scientists in quantum computing says that his lab has switched on the power to “Japan’s first full-stack, neutral atom quantum computer,” according to a recent press release.
This announcement is not linked with peer reviewed research, but the lab leader, photo-molecular physicist Kenji Ohmori, has decades of research, publication, and leadership in the field. The computer, named Shunkai, is part of a nationwide Japanese consortium of universities and corporate interests that seeks to realize “a fault-tolerant universal quantum computer that will revolutionize economy, industry, and security by 2050.”
There are many flavors of experimental quantum computers on our busy planet today. That’s because, to date, there’s definitely never been a “fault-tolerant universal quantum computer” by a very long stretch. When traditional digital computers were developed, they had guardrails because of the way our electrical and logic industries had developed before them. Quantum computing is a deeply different paradigm where the next step is more ambiguous: all the options have drawbacks and limitations that are more confusing and pervasive than what we have now. It’s like VHS versus Betamax, but on steroids.
