NMR Simulation Of 3-qubit Grover Quantum Search Algorithm

Quantum calculation is a new subject, recently developed. It can deal with information technology using quantum mechanics . With the growth of theory and technology, at the same time, more experts and scholars joining in the research in the field, quantum calculation is rapidly growing and promotes the development and progress of computer science. In the not-far future, our society will entry quantum information times.For the recent 20 years, quantum calculated theory has shown that quantum calculation is much superior to classic calculation in many ways. Especially, the superiority is more evident in some simulation of quantum system and large number factoring questions etc. Meantime, many quantum algorithms are presented. We mainly study Grover quantum search algorithm which can speed search rate of the classic algorithms by square. This paper is based on our studying Grover quantum algorithm, apprehending and applying the multiple-quantum operator algebra spaces and NMR technology. We present the design of 3-qubit pulse sequences of Grover quantum employing NMR physical technology. Furthermore, we verify what we design is true, reasonable and feasible using QCE. In the total course of designing NMR pulse sequences, the key to problems lies in how to change unitary transformation corresponding to Grover quantum search algorithm for a series of 1-qubit and 2-qubit quantum gates products, in particular, how to exactly decompose the inter-nuclear interaction as a sequence of a limited number of one- and two-qubit gates .These provide critical values for the research of quantum calculated theory and physical realization of quantum computers.
