摘 要:Quantum search algorithm,which can search an unsorted database quadratically faster than any known classical algorithms,has become one of the most impressive showcases of quantum *** has been implemented using various quantum ***,we demonstrate both theoretically and experimentally that such a fast search algorithm can also be realized using classical electric *** classical circuit networks to perform such a fast search have been *** has been shown that the evolution of electric signals in the circuit networks is analogies of quantum particles randomly walking on graphs described by quantum *** searching efficiencies in our designed classical circuits are the same to the quantum *** classical circuit networks possess good scalability and stability,the present scheme is expected to avoid some problems faced by the quantum ***,our findings are advantageous for information processing in the era of big data.
