利用仲氢诱导极化技术实现Deutsch算法
Implementation of Deutsch Algorithm Using Para-Hydrogen Induced Polarization
摘要
Abstract
The NMR system is one of the physical systems that can be used to realize quantum computation. However, NMR-based quantum computing could have many drawbacks with increasing qubit number. One of the underlying reasons is that the signal of pseudo-pure state decreases exponentially with increasing qubit number. Besides, the process required to prepare a pseudo-pure state becomes more complicated as the spin system gets larger. Furthermore, the pseudo-pure state in NMR system is in fact a mixed state, making it difficult to realize quantum entanglement. In this paper, we used parahydrogen induced polarization (PHIP) technique to prepare a genuine pure state for NMR quantum computation with significantly enhanced signal intensity. The initial state was applied to implement a two-qubit Deutsch-Jozsa algorithm and a three-qubit Deutsch-like algorithm.关键词
