Physics' evolution toward computing (Q2240987)

The paper is devoted to the problem of describing quantum computing by using quantum mechanics: The authors show various multiple operations through both the superposition and the phase factor connected by the phase kick-back formation. The authors review the construction of logical functions in a Boolean algebra, like AND, OR, XOR, and in general the typical arithmetic operations in the binary system. Then the authors consider the implementation of commercial quantum-gated computers for SUM, the carry function \(C_0(A,B)\), etc.
