We show that a special type of measurements, called symmetric informationally complete
positive operator-valued measures (SIC POVMs), provide a stronger entanglement detection …

We present a quantum information theoretic version of the Klein-Nishina formula. This
formulation singles out the quantity, the a priori visibility, that quantifies the ability to deduce …

Entanglement detection is one of the core tasks in quantum information processing. Based
on a broad class of informationally complete symmetric measurements, a series of …

The detection of entanglement is a basic problem in quantum information theory. Our goal in
this work is to study the quantum separability problem with respect to a broad class of …

Quantum measurements based on mutually unbiased bases, mutually unbiased
measurements and general symmetric informationally complete positive operator valued …

Discrete structures in Hilbert space play a crucial role in finding optimal schemes for
quantum measurements. We solve the problem of whether a complete set of five …

Finite tight frames play an important role in miscellaneous areas, including quantum
information theory. Here we apply a class of tight frames, equiangular tight frames, to …

Coherence is a foundational feature of quantum mechanics and is increasingly becoming
recognized as a key resource for quantum theory. Based on coherence measure, our goal in …

In this work, the concept of mutually unbiased frames is introduced as the most general
notion of unbiasedness for sets composed by linearly independent and normalized vectors …

We study the quantum separability problem by using general symmetric informationally
complete measurements and present a separability criterion for arbitrary dimensional …
