Abstract:

The logical relationship can be described with the Boolean functions. The quantum Boolean function are introduced and defined because quantum logic relationship is reversible. The irreversible logic operations are accomplished in the quantum reversible logic circuits by introducing auxiliary qubits and adding the output signal of quantum bits to distinguish the different bit. Then the irreversible logical gate can be realized in quantum circuits. Also we give the optimized quantum circuit about the irreversible logical gate which can be realized.

Key words: irreversible quantum logical gate, quantum circuit, logical function, quantum logical function, redundancy qubits
