Reversible Logic Circuit for One-Dimensional Quantum Walk Based on NCP Quantum Gates Library
The design proposal of reversible logic circuit for one-dimensional quantum walk based on NCP quantum gates library is presented.According to the features of the one-dimensional quantum walk
this circuit is divided to two parts
one part is quantum coin tossing and the other part is S operation.Besides the work above
this paper thoroughly analyses the one-dimensional quantum walk and builds a mathematical model of the one-dimensional quantum walk and uses controlled add-sub circuit to realize the S operation.At present the researches on quantum walk often limited to the mathematical theory and analysis.Depend on the primitive recursive
Mathematical expression of every step of the one-dimensional quantum walk is given in this paper;the circuit studied in this paper describes element operation of the one-dimensional quantum walk
and make this modular which contribute to the realization for the algorithm of one-dimensional quantum walk.
