Abstract
A “Controlled-NOT” (CNOT) gate is an elementary building block for an ideal quantum computer. The key advantage of a quantum computer lies in its capability to operate coherently when the quantum bits are in a superposition state of the basis states |S0〉 and |S1〉. In this paper, we closely analyze the operation of an ideal quantum "Controlled-NOT" logicgate (Figure 1 and Table 1).
