QI Xueme · Chinese Journal of Quantum Electronics · 2013
The fault tolerant reversible Hamming code circuits were designed in order to test the reliability of the data in the transmission process.A new reversible gate named four variables parity preserving gate(FVG) was proposed,and the quantum equivalent implementations of FVG was also given.Fault tolerant reversible code encoding and detection circuits were designed using FVG and existing gates.Taking the design of the(7,4) Hamming code as an example,its circuit performance was evaluated in terms of quantum cost and delay.The results prove that its performance is improved by 10%to 20%than existing counterparts.Simulation results indicate that the logic structures of circuit are correct and their performances are reliable.
