IBM has unveiled a new quantum computing chip and machine. It marks a significant step towards building larger and more powerful quantum systems in the future. This advancement comes amid fierce competition in the field. With other players like Microsoft, Google, and Baidu also striving to develop quantum technologies.
Quantum computing promises to revolutionize various industries by harnessing the principles of quantum mechanics to perform calculations at unprecedented speeds. However, building reliable and error-free quantum machines remains a major challenge.
Chip connectivity and error correction
IBM’s new approach focuses on two key areas: chip connectivity and error correction. The company has devised a method for connecting multiple quantum chips within a machine and further connecting multiple machines together. This, combined with a novel error-correction code, is expected to pave the way for compelling quantum machines by 2033.
The first machine to utilize these technologies is called Quantum System Two, featuring three “Heron” chips. IBM’s research director, Dario Gil, predicts a steady pace of progress until 2029, followed by a rapid acceleration in capabilities thanks to the full impact of the error-correction advancements. He compares this anticipated growth to the recent surge in AI capabilities after years of steady development.
Intense competition and rapid progress
Gil emphasizes the importance of connecting these new chips: “You’re going to have to tie them together. You’re going to have to do many of these things together to be practical about it. Because if not, it’s just a paper exercise.”
IBM is not alone in its aggressive timeline for quantum machines. Startup PsiQuantum, collaborating with GlobalFoundries on chip production, has announced plans for a commercial machine within six years. These ambitious goals highlight the intense competition and rapid progress within the field of quantum computing.
This news represents a significant milestone in the quest for practical and powerful quantum computing. With continued advancements in chip technology, error correction, and connectivity, we can expect to see increasingly capable quantum machines in the years to come.
