摘要:

提出了一种基于n阶耦合算符的可扩展方法,在n量子比特改进的Deutsch-Jozsa(D-J)量子算法中构造f依赖的相变.新的n比特纠缠变换很容易通过相邻自旋之间的J耦合实现。然后用液态核磁共振(NMR)技术对七量子比特改进的D-J量子算法和七阶耦合变换进行了实验验证。该方法为在n-qubit NMR量子计算机上产生一般的n量子比特纠缠态和模拟n体相互作用提供了可能。

英文摘要:

We propose a scalable method on the basis of nth-order coupling operators to construct f-dependent phase transformations in the n-qubit modified Deutsch-Jozsa (D-J) quantum algorithm. The novel n-qubit entangling transformations are easily implemented via J-couplings between neighboring spins. The seven-qubit modified D-J quantum algorithm and seventh-order coupling transformations are then experimentally demonstrated with liquid state nuclear magnetic resonance (NMR) techniques. The method may offer the possibility of creating generally entangled states of n qubits and simulating n-body interactions on n-qubit NMR quantum computers.
