Local distinguishability of orthogonal quantum states is an area active research in information theory. However, most the relevant results are about local bipartite Hilbert space and very little known multipartite case. In this paper we present a generic method to construct completable $n$-partite $(n\ensuremath{\ge}3)$ product basis with only $2n$ members, which exhibits nonlocality without entanglement $n$ parties, each holding system any finite dimension. We give effective proof basis....
Abstract Oblivious transfer (OT) protocol is an essential building block for secure multiparty computation. The transmission of quantum messages conductive in executing complex computation tasks and even distributed tasks. However, as important form OT protocol, existing all‐or‐nothing protocols only work the classical thus limiting application scenarios. To tackle this issue, a counterfactual proposed messages. Compared with messages, has three advantages: i) it achieved without any...
Quantum Anonymous Private Information Retrieval (QAPIR) allows a user to retrieve an item from database anonymously thus achieving better privacy. Recently, Khan <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">et al</i> . proposed the first QAPIR protocol [IEEE Trans. Commun. 70(6), 4026-4037 (2022)] which is only known protocol. However, symbol coincidence error occurs when main ingredients are combined form this Furthermore, it requires...
Quantum network coding is expected to enable multiple quantum data packets be fused before the transmission via bottleneck channel in order improve efficiency and total throughput of networks. Although several schemes have been constructed, they are unable meet practical application requirements due fact that lack a complete security solution. To tackle this issue, secure scheme constructed. Compared with existing methods, proposed more most importantly it can provide against both...
As we know, unextendible product basis (UPB) is an incomplete whose members cannot be perfectly distinguished by local operations and classical communication. However, very little known about those locally indistinguishable bases that are not UPBs. In this paper, first construct a series of orthogonal completable but distinguishable in general m ⊗ n (m ≥ 3 3) quantum system. particular, give so far the smallest number states arbitrary systems. Furthermore, small 3). All results lead to...
Recently, much attention have been paid to the constructions of nonlocal multipartite orthogonal product states. Among existing results, some are relatively complex in structure while others many constraint conditions. In this paper, we first give a simple method construct set states ${\ensuremath{\bigotimes}}_{j=1}^{n}{\mathbb{C}}^{d}$, where $d,\phantom{\rule{0.16em}{0ex}}n$ two positive integers, $d\ensuremath{\ge}2$ and $n\ensuremath{\ge}3$. Then proof for local indistinguishability...
Unextendible product bases (UPBs) play an important role in quantum information theory. However, very little is known about UPBs Hilbert space of local dimension more than three. In this paper, we study the qutrit-ququad system and find that there only exist six, seven eight-state UPBs. We completely characterize six-state seven-state For UPBs, classes are found. As auxiliary results, distinguishability by separable measurements, exists a UPB cannot be distinguished.
