1.1 Quantum bits – qubits
1.1.1 Definition of a qubit and geometric representation
Conventional information systems are based on Boolean logic. In this framework, the unit of information, called a "bit", is a number that can take on two distinct values: 0 or 1. These "bits" are generally materialized by physical systems that can exist in two easily distinguishable states, such as the presence or absence of a voltage, charge or current. Information is coded in the form of bit sequences, which the computer manipulates....
