A Bit not as a Unit of Information - A Qubit is not a Unit of Quantum Information

While Shannon introduced “binary digits, or more briefly bits” as units of information, a binary digit (and, thus, a bit) originally and still means a character of “0” or “1”, which may be represented by a binary symbol or storage cell. As a result, a bit often means a binary symbol or storage cell, which is inherited by a “qubit”, a quantum bit, introduced by Schumacher as “the fundamental units of quantum information”. Schumacher himself uses a bit, not a qubit, as a unit of quantum information and a qubit is a quantum binary symbol or storage cell.
