论文摘要
量子信息以与Ancilla纠缠的形式可以通过相互作用传输到第三个系统。在这里，我们及时研究了纠缠传播的这一过程。使用纠缠单调的负性，我们确定相互作用的倾向是如何产生，转移或丢失的纠缠取决于哈密顿人和初始状态的选择。这三个倾向是由汉密尔顿和国家依赖的数量捕获的，我们称之为消极的敏感性，消极性的传播性和消极脆弱性。例如，这些概念可以作为量子技术（例如机器学习量子误差校正）中的成本功能。
Quantum information, in the form of entanglement with an ancilla, can be transmitted to a third system through interaction. Here, we investigate this process of entanglement transmission perturbatively in time. Using the entanglement monotone negativity, we determine how the proclivity of an interaction to either generate, transfer or lose entanglement depends on the choice of Hamiltonians and initial states. These three proclivities are captured by Hamiltonian- and state-dependent quantities that we call negativity susceptibility, negativity transmissibility and negativity vulnerability respectively. These notions could serve, for example, as cost functions in quantum technologies such as machine-learned quantum error correction.
