We study separability problem using general symmetric informationally complete measurements and propose separability criteria in $$\mathbb {C}^{d_{1}}\otimes \mathbb {C}^{d_{2}}$$Cd1⊗Cd2 and $$\mathbb {C}^{d_{1}}\otimes \mathbb {C}^{d_{2}}\cdots \otimes \mathbb {C}^{d_{n}}$$Cd1⊗Cd2⋯⊗Cdn. Our criteria just require less local measurements and provide experimental implementation in detecting entanglement of unknown quantum states. 

Informational power of the Hoggar SIC-POVM

Among positive operator valued measures (POVMs) representing general quantum measurements, symmetric informationally complete (SIC) POVMs, called by Christopher Fuchs ‘mysterious entities’, play a

It can be found this witness detects more entanglement than previous separability method given also by SIC-POVM.

Improved separability criteria via some classes of measurements

Based on mutually unbiased measurements and general symmetric informationally complete positive-operator-valued measures, separability criteria for bipartite quantum states are presented, which, by theoretical analysis, are stronger than the related existing criteria via these measurements.

We analyze tight informationally complete measurements for arbitrarily large multipartite systems and study their configurations of entanglement. We demonstrate that tight measurements cannot be

This work studies the quantum separability problem by using general symmetric informationally complete measurements and presents a separability criterion for arbitrary dimensional bipartite systems that is more powerful than the existing ones in entanglement detection.

Construction of general symmetric-informationally-complete–positive-operator-valued measures by using a complete orthogonal basis

A general symmetric informationally complete (GSIC)-positive operator valued measure (POVM) is known to provide an optimal quantum state tomography among minimal IC-POVMs with a fixed average purity.

It is proved that a necessary condition for separability is that a matrix, obtained by partial transposition of {rho}, has only non-negative eigenvalues.

General SIC measurement-based entanglement detection

The criterion for bipartite quantum states is effective in detecting several well-known classes of quantum states, and the criterion for two-qudit states requires less local measurements than the one based on mutually unbiased measurements.

Entanglement detection via some classes of measurements

Based on the mutually unbiased bases, the mutually unbiased measurements and the general symmetric informationally complete positive-operator-valued measures, we propose three separability criteria

The computable cross-norm (CCN) criterion is a powerful analytical and computable separability criterion for bipartite quantum states, which is also known to systematically detect bound entanglement.

Notes on general SIC-POVMs

It is obtained that for a given density matrix and any general SIC-POVM, the so-called index of coincidence of generated probability distribution is exactly calculated and state-dependent entropic bounds for a single general Sic-PovM are obtained.

We investigate correlations among complementary observables. In particular, we show how to take advantage of mutually unbiased bases (MUBs) for the detection of entanglement in arbitrarily

An entanglement witness (EW) is an operator that allows to detect entangled states. We give necessary and sufficient conditions for such operators to be optimal, i.e. to detect entangled states in an
