Google announced a new quantum computing milestone with its Willow chip.GoogleGoogle unveiled its Willow chip this week, marking a milestone in the quantum computing space.One quantum researcher compared Google's advancement to mobile networks jumping from 1G to 2G.While the news represents a breakthrough, real-world applications are likely still years away.Google's new Willow chip may not show up in consumer products in the near future — however, quantum computing researchers say it represents a significant breakthrough in the field.That's because the chip solves a challenge that's existed in quantum computing for nearly 30 years, Google said in its announcement earlier this week.The challenge is reducing the amount of errors quantum computers generate while operating.
