Abstract: Abstract: Synthesis of quantum reversible logic circuits means to automatically construct desired quantum reversible logic circuits with minimal quantum cost. The truth table synthesis of quantum logic, one of most useful in reversible logic synthesis of quantum circuits, contains obverse direction, reverse direction and double action synthesis. Hamming distance is defined and popularized to lateral Hamming distance, vertical Hamming distance and cross Hamming distance. The quantum reversible logic circuits compound synthesis in the popularized Hamming distance is discussed. It is shown that the compound synthesis produces better results and greater efficiency than the previous approaches.
