In quantum computing, a qubit or quantum bit (sometimes qbit) is the basic unit of quantum information: Z
Zepto-
Zepto (unit symbol z) is a unit prefix in the metric system denoting a factor of 10−21 or 0.000000000000000000001.
Adopted in 1991, it comes from the Latin septem, meaning “seven”, since it is equal to 1000−7.
Examples of its use:
The electric charge on one electron: 160.217657 zeptocoulombs (zC).
One zeptomole (zmol) of substance contains 602 particles.
The human insulin molecule has a mass of roughly 10 zeptograms.
