 We can also introduce operations on multiple qubits. There is a class of two-qubit operators in which the leftmost qubit controls whether an operation is applied to the rightmost qubit. A controlled-NOT (C<sub>NOT</sub>) applies a NOT operator (X) to the rightmost qubit when the left qubit is \|1> and otherwise makes no change. The C<sub>NOT</sub> is defined as follows:

-Quantum computing is based on three concepts: superposition, entanglement and observational probability. Superposition and entanglement are consequences of use of vectors to describe states. The quantum nature arises because of the use of probability to provide a physical meaning when the state of qubits is observed
