system where the two basis qubit states are usually written as |0⟩ (“|⟩” represent Dirac notation) and |1⟩. A qubit can be in state |0⟩, |1⟩ or (unlike a classical bit) in a linear combination of both states. For example one qubit vector presentation is: |ψ⟩ = α|0⟩ + β|1⟩ where ψ is a qubit and (α,
