摘要:

基于仿射映射提出了一种测试量子纠缠的新方法. 该文首先证明了二维希尔伯特空间中两个特殊仿射映射的完全正性, 然后基于完全正仿射映射给出了纠缠检验, 最后通过实例说明了检验的性能.

关键词: 仿射映射, 纠缠检验, 纠缠态, Hadamard 门

Abstract:

In this paper, we present a new method to test quantum entanglement based on affine mapping. First, we prove the complete positivity of two special affine mappings in two-dimensional Hilbert space. Then, based on this completely positive affine mapping, we give our entanglement test. At last, we illustrate the capability of our test with two examples.

Key words: Affine mapping, Entanglement test, Entangled state, Hadamard gate
