Pin It

Atoms trapped in optical lattices could be used to make ultraprecise atomic clocks and quantum computers, provided the number of trapped atoms is precisely known. A new method can count the atoms in a one-dimensional trap without disturbing too many of them. This minimally invasive technique can be used to control the number of atoms with an uncertainty that’s nearly a factor of 10 less than the random, so-called “shot,” noise.
