论文摘要
量子纠缠在基本和实际方面都是量子力学的核心。量子状态的纠缠已得到广泛的研究，但是，尽管其重要性，但纠缠了操作员的纠缠并未得到太多研究。在这里，我们提出了一个计划，以基于当地运营的连贯叠加来实现任意纠缠的操作。然后，我们通过实验实施了光子系统中的几个有趣的两倍纠缠操作。我们还讨论了我们方案的概括，以扩大超级操作的数量和Qubits的数量。由于我们计划的简单性，我们认为它可以降低量子电路的复杂性或所需资源，并提供见解以调查纠缠操作的属性。
Quantum entanglement lies at the heart of quantum mechanics in both fundamental and practical aspects. The entanglement of quantum states has been studied widely, however, the entanglement of operators has not been studied much in spite of its importance. Here, we propose a scheme to realize arbitrary entangled operations based on a coherent superposition of local operations. Then, we experimentally implement several intriguing two-qubit entangled operations in photonic systems. We also discuss the generalization of our scheme to extend the number of superposed operations and the number of qubits. Due to the simplicity of our scheme, we believe that it can reduce the complexity or required resources of the quantum circuits and provide insights to investigate properties of entangled operations.
