Realizing Deutsch-Like Algorithm With Hydrogen Induced Polarization Technology And Optimal Control Method In The Application Of Nitrogen-14 With Pulse

Nuclear magnetic resonance (NMR) technology is one of the hot areas of multidisciplinary research in physics. Currently quantum technology is one of the very mature methods. We have flexible to use NMR technology to finish the experiments.The first part of this paper research is to use optimal control theory to design some coop pulses for direct detection of 14N. The biggest advantage of this new pulse is lower the traditional pulse power required, reduce the time, improve sensitivity. And compare with the DANTE sequences and traditional methods. And implement quantum algorithm.This paper introduces our new calculation works on PHIP systems.The NMR system is one of the effective physical system to realize quantum computation. But with the quantum number increase, there exist many limitations to realize computing task by NMR, one of the reason is the initial state-pseudo pure state, also due to the pseudo pure state in NMR preparation is a mixed state, there are some disputes to realize quantum information. In this paper, we use PHIP for experimental initial state, can solve the separation of mixed state, and the signal intensity is significantly enhance, we use this experiment state implement the Deutsch algorithm with three qubits. We optimize the state of PASADENA experiment, which can be studied that taking full advantages para-hydrogen initial state for quantum computing implementation.
