Physicists at the University of Oxford have set a new world record for how accurately a quantum bit, or qubit, can be controlled. They achieved the lowest error rate ever measured in a quantum logic operation: just 0.000015 percent. That’s only one error in 6.7 million operations! That’s nearly ten times better than the previous record, which was also set by the same team a decade ago.
To put it into perspective, you’re more likely to be struck by lightning this year (1 in 1.2 million) than for one of Oxford’s quantum gates to make a mistake.
