量子格子气计算的实验验证

Experimental Demonstration of Quantum Lattice Gas Computation

Marco A. Pravia, Zhiying Chen, Jeffrey Yepez, David G. Cory

摘要:

我们报告了扩散方程的量子格子气算法的系综核磁共振(NMR)实现。该算法采用了一系列量子信息处理器共享经典信息,一种新的架构被称为II型量子计算机。这个具体的实现提供了一个测试示例,从中可以探索这种新计算范式的优势和局限性。NMR实验包括将质量密度编码到16个双量子位量子信息处理器的阵列上,然后通过算法的7个时间步长进行计算。结果表明,与扩散动力学的解析解吻合良好。我们还描述了NMR实现的数值模拟。模拟有助于确定实验误差的来源,并有助于确定实施的限制。

英文摘要:

We report an ensemble nuclear magnetic resonance (NMR) implementation of a quantum lattice gas algorithm for the diffusion equation. The algorithm employs an array of quantum information processors sharing classical information, a novel architecture referred to as a type-II quantum computer. This concrete implementation provides a test example from which to probe the strengths and limitations of this new computation paradigm. The NMR experiment consists of encoding a mass density onto an array of 16 two-qubit quantum information processors and then following the computation through 7 time steps of the algorithm. The results show good agreement with the analytic solution for diffusive dynamics. We also describe numerical simulations of the NMR implementation. The simulations aid in determining sources of experimental errors, and they help define the limits of the implementation.
