Infinitely small does not exist
Dirac's constant is the smallest unit of information. It is a quantum of angular momentum, with the value
Explanation
In quantuminformatics, you work with qubits. A qubit can be represented with a linear combination of two quantum states as
|ψ⟩ = α |0⟩ + β |1⟩
where α and β are complex probability amplitudes.
HistoryThe constant is named after the British quantum physicist Paul Dirac (1902 - 1984). |
