量子信息线的量子比特率

Achievable Qubit Rates for Quantum Information Wires

Hulya Yadsan-Appleby, Tobias J. Osborne

摘要:

假设爱丽丝和鲍勃可以分别进入一个电子系统的两个独立区域,该系统在一个规则的一维束缚原子晶格中运动。我们考虑的问题是,通过这条量子信息线,尽可能多地传递由量子比特率测量的量子信息。我们描述了一个协议,其中Alice和Bob可以实现这些系统的量子比特率,其与每单位时间的N^(-1/3)量子比特成比例,其中N是晶格位置的数量。我们的协议也同样的功能,通过t-J和哈伯德模型建模的相互作用的存在。

英文摘要:

Suppose Alice and Bob have access to two separated regions, respectively, of a system of electrons moving in the presence of a regular one-dimensional lattice of binding atoms. We consider the problem of communicating as much quantum information, as measured by the qubit rate, through this quantum information wire as possible. We describe a protocol whereby Alice and Bob can achieve a qubit rate for these systems which is proportional to N^(-1/3) qubits per unit time, where N is the number of lattice sites. Our protocol also functions equally in the presence of interactions modelled via the t-J and Hubbard models.
