Alphabet’s sagging stock has been primed for any good news, but quantum computing’s payoff is years away at best.

Google says their researchers developed a new chip, "Willow," they say overcomes a main hurdle in quantum computing.

Google captivated the tech world Monday with Willow, a new quantum chip that outperformed even the world’s best supercomputer on an advanced test, and experts say this week’s revelations are just the start of a new phase of cutting-edge computing.

Through a newly unveiled quantum chip called Willow, Google engineers have passed a significant milestone in error handling. Specifically, they've been able to keep a single logical qubit stable enough so errors occur maybe once every hour,
