A major milestone has just been reached in
quantum computing.
Three separate teams around the world have passed the 99 percent accuracy threshold for silicon-based quantum computing, placing error-free quantum operations within tantalizing grasp.
In Australia, a team led by physicist Andrea Morello of the University of New South Wales achieved 99.95 percent accuracy with one-qubit operations, and 99.37 percent for two-qubit operations in a three-qubit system.
In the Netherlands, a team led by physicist Seigo Tarucha of Delft University of Technology achieved 99.87 percent accuracy for one-qubit operations, and 99.65 percent for two-qubit operations in quantum dots.
Finally, in Japan, a team led by physicist Akito Noiri of RIKEN achieved 99.84 percent accuracy for one-qubit operations and 99.51 percent for two-qubit operations, also in quantum dots.
All three teams have published their results in the journal
Nature today
.
"Today's publication in Nature shows our operations were 99 percent error-free," Morello says.
Any one of these papers alone would be a significant achievement. The fact that all three teams have reached the same milestone independently suggests that quantum computing will now be surging ahead.
