A quantum bit, or qubit, is the fundamental information unit of quantum computing.
Despite a single qubit living in a seemingly strange 2D complex Hilbert space, we can visualize it, its
superposition.
If you have seen descriptions of qubits elsewhere, you may have read something like
“a qubit
implements a two-state quantum mechanical system and is the quantum analog of a classical
bit.”
A bit, also has two states, those being 0 and 1.
