The theoretical measurement accuracy could be as high as several picoseconds.
其测时隙的精度理论上可达皮秒量级。

And the process is exceedingly fast: experimental devices have turned electrons on their heads in a few picoseconds (trillionths of a second).
而且整个程序进行得极快:实验用的装置,只消在几皮秒(10 - 12秒)以内,就能让电子转头。

Physicists have no trouble using, on the one hand, picoseconds (trillionths of a second) or even femtoseconds (quadrillionths of a second) to discuss time at the atomic scale.
