SAN FRANCISCO (Reuters) -IBM announced on Wednesday it has built a new experimental quantum computing chip called Loon that demonstrates it hit a key milestone toward making useful quantum computers before the end of the decade.

Quantum computers could someday solve problems that would take classical computers thousands of years. But due to the uncertain nature of quantum mechanics, the chips are prone to errors.

Correcting those errors is the key focus of tech giants such as Alphabet’s Google and Amazon that are chasing quantum computers alongside IBM. In 2021, IBM proposed a new way of doing error correction: adapt an algorithm for improving cellphone signals to quantum computing and run it on a combination of quantum chips and classical computing chips.
