qubit quantum information ion bit superposition
The qubit serves as the basic unit of quantum information.
It represents a two-state system, just like a classical bit, except that it can exist in a superposition of its two states.
In one sense, a superposition is like a probability distribution over the two values.
However, a quantum computation can be influenced by both values at once, inexplicable by either state individually.
In this sense, a "superposed" qubit stores both values simultaneously.
