Scientists have reached what is described as the ultimate quantum limit for measurement on a surface

Researchers say they have reached what is described as the ultimate quantum limit for measurement on a surface, a benchmark for precision in sensing at the smallest scales. The claim is reported so far only by Google, with no detail yet available on which team carried out the work, where it was published, or what practical applications might follow. Independent verification of the findings has not been reported.
