Futurizonte Editor’s Note: A decade ago, while teaching a class about philosophy of technology, I mentioned quantum computers and most of my students laughed, saying “That will never happened”. I wonder if they are still laughing.

From the article:

We just moved years closer to viable quantum computers.

A company has revealed the results of benchmarking experiments that demonstrate how an advanced error-suppression method increased the probability of success for quantum computing algorithms to succeed on real hardware, according to a press release shared with Interesting Engineering via email.

And the new method increased the likelihood of success by an unprecedented 2,500%.

Today, most quantum computers can only handle the simplest and shortest algorithms, since they’re so wildly error-prone. And in recent algorithmic benchmarking experiments executed by the U.S. Quantum Economic Development Consortium, the errors observed in hardware systems during tests were so serious that the computers gave outputs statistically indiscernible from random chance.

That’s not something you want from your computer.

But by employing specialized software to alter the building blocks of quantum algorithms, which are called “quantum logic gates,” the company Q-CTRL discovered a way to reduce the computational errors by an unprecedented level, according to the release.

The new results were obtained via several IBM quantum computers, and they also showed that the new quantum logic gates were more than 400 times more efficient in stopping computational errors than any methods seen before. It’s difficult to overstate how much this simplifies the procedure for users to experience vastly improved performance on quantum devices.

“This is the most powerful error-suppression technology ever demonstrated, and delivers an enormous competitive advantage to users,” said CEO and Founder of Q-CTRL Michael J. Biercuk, who’s also a professor, in the release. “These simple-to-use techniques will likely enable organizations to achieve useful quantum computing years ahead of current projections.”
