论文摘要
多部分无法扩展的产品库（UPB）的构建是量子信息中的基本问题。我们分别使用现有的四量和五倍的UPB，分别构建两个$ 2 \ times2 \ times4 $和$ 2 \ times2 \ times2 \ times2 \ times2 \ times4 $ UPB的家庭。作为一种应用，我们根据几何纠缠的几何量度来构建多部分阳性纠缠状态及其纠缠特性的新型家族。
The construction of multipartite unextendible product bases (UPBs) is a basic problem in quantum information. We respectively construct two families of $2\times2\times4$ and $2\times2\times2\times4$ UPBs of size eight by using the existing four-qubit and five-qubit UPBs. As an application, we construct novel families of multipartite positive-partial-transpose entangled states, as well as their entanglement properties in terms of the geometric measure of entanglement.
