We study entanglement witness and present a construction of entanglement witnesses in terms of the mutually unbiased measurements (MUMs). These witnesses include the entanglement witnesses constructed from mutually unbiased bases (MUBs) as a special case. Comparing with the dimension dependence of MUBs, the witnesses can be always constructed from a complete set of $d+1$ MUMs for any dimension $d$. We show that our witness can detect entanglement better than previous separability criterion… 
Entanglement Witnesses Based on Symmetric Informationally Complete Measurements
TLDR
It can be found this witness detects more entanglement than previous separability method given also by SIC-POVM.
Indecomposability of entanglement witnesses constructed from symmetric measurements
We propose a family of positive maps constructed from a recently introduced class of symmetric measurements. These maps are used to define entanglement witnesses, which include other popular
Entanglement witnesses from mutually unbiased measurements
TLDR
A new family of positive, trace-preserving maps is introduced using the mutually unbiased measurements, which generalize the notion of mutual unbiasedness of orthonormal bases to define entanglement witnesses whose indecomposability depends on the characteristics of the associated measurement operators.
Constructing Entanglement Witnesses from Two Mutually Unbiased Bases
We study entanglement witnesses (EWs) and construct a linear map by taking two groups of mutually unbiased bases (MUBs) of two Hilbert spaces. We provide two new relations about matrices (may not be
Mutually unbiased measurements with arbitrary purity
TLDR
This contribution provides a class of MUM that encompasses the full range of purity in a d-dimension space and examines the minimal number of measurements needed to detect entanglement of bipartite states.
Generalization of Pauli channels through mutually unbiased measurements
We introduce a new generalization of the Pauli channels using the mutually unbiased measurement operators. The resulting channels are bistochastic but their eigenvectors are not unitary. We analyze

Covariance matrices and the separability problem.
TLDR
This work proposes a unifying approach to the separability problem using covariance matrices of locally measurable observables and leads to insights into the relations between several known entanglement criteria--such as the computable cross-norm and local uncertainty criteria--as well as their limitations.
OPTIMAL EAVESDROPPING IN QUANTUM CRYPTOGRAPHY. I. INFORMATION BOUND AND OPTIMAL STRATEGY
TLDR
It is shown that both bounds can be attained simultaneously by an optimal eavesdropping probe, and an upper bound to the accessible information in one basis, for a given error rate in the conjugate basis is derived.
