E arlier this week , Google hit a significant quantum computing milestone , using its Willow chip to make calculations an estimated 13,000 times faster than a conventional computer chip. The tech giant published its findings in Nature .

This isn’t the first time Google—or other quantum computing companies—have claimed this type of “quantum supremacy,” but two things stand out about these results. First, these calculations are directly applicable to practical problems; the com
