在本文中，我们提出了一个协议的实施正算子值的措施（POVM）的大规模费米量子比特。我们提出了实现非色散量子比特传输，自旋旋转和自旋偏振分束器操作的方法。我们的计划实现线性opticslike控制的空间范围的量子位考虑基态电子被困在最小的表面声波在半导体异质结构。此外，我们数值模拟了高保真POVM进行普罗克鲁斯特纠缠蒸馏的框架下，我们的计划，使用实验现实的潜力。我们的协议不仅可以适用于纯合奏与粒子对已知相同的纠缠，但也现实合奏的粒子对分布的纠缠熵。本文为未来的量子技术提供了一种实验上可实现的设计。
In this paper we present a protocol for the implementation of a positive-operator-valued measure (POVM) on massive fermionic qubits. We present methods for implementing nondispersive qubit transport, spin rotations, and spin polarizing beam-splitter operations. Our scheme attains linear opticslike control of the spatial extent of the qubits by considering ground-state electrons trapped in the minima of surface acoustic waves in semiconductor heterostructures. Furthermore, we numerically simulate a high-fidelity POVM that carries out Procrustean entanglement distillation in the framework of our scheme, using experimentally realistic potentials. Our protocol can be applied not only to pure ensembles with particle pairs of known identical entanglement, but also to realistic ensembles of particle pairs with a distribution of entanglement entropies. This paper provides an experimentally realizable design for future quantum technologies.
