Local distinguishability of orthogonal quantum states is an area of active research in
quantum information theory. However, most of the relevant results are about local …

Recently, much attention have been paid to the constructions of nonlocal multipartite
orthogonal product states. Among the existing results, some are relatively complex in …

Unextendible product bases (UPBs) play a key role in the study of quantum entanglement
and nonlocality. Here we provide an equivalent characterization of UPBs in graph-theoretic …

We completely characterize the condition when a tile structure provides an unextendible
product basis (UPB) and construct UPBs of different large sizes in C m⊗ C n. In particular …

Nonlocality is arguably one of the most fundamental and counterintuitive aspects of quantum
theory. Nonlocal correlations could, however, be even more nonlocal than quantum theory …

We consider a protocol for sharing quantum states using continuous variable systems.
Specifically we introduce an encoding procedure where bosonic modes in arbitrary secret …

It has recently been shown that probabilistic protocols based on postselection boost the
performances of the replication of quantum clocks and phase estimation. Here we …

The impossibility of superluminal communication is a fundamental principle of physics. Here
we show that this principle underpins the performance of several fundamental tasks in …

The multiqubit bound entangled states that are uniformly mixed over the subspaces
complementary to unextendible product bases (UPBs) are interesting members from the …
