Revisiting Boole Equation in the Quantum Context

Abstract

In this work we try to clarify the fundamental relationship between bits and qubits, starting from very simple George Boole equation. We derive a generic and compact expression for basis vectors of qubit which can be useful in further applications. We also derive a generic form for the projection operator in the quantum information space. The results are also extended to higher d-level cases of qutrits and qudits.
