Recent years have seen significant advances in the study of symmetric informationally
complete (SIC) quantum measurements, also known as maximal sets of complex …

Overlap between quantum states or observables is a fundamental quantity in quantum
theory. Equioverlapping measurements arise naturally when considering quantum …

We compute the informational power for the Hoggar symmetric informationally complete
positive operator-valued measure (SIC-POVM) in dimension eight, ie, the classical capacity …

It is shown that a normalized complex Hadamard matrix of order 6 having three distinct
columns each containing at least one-1 entry, necessarily belongs to the transposed Fourier …

Informationally overcomplete measurements find important applications in quantum
tomography and quantum state estimation. The most popular are maximal sets of mutually …

The problem of packing n-dimensional subspaces of m-dimensional Euclidean space such
that these subspaces are as far apart as possible was introduced by Conway, Hardin and …

We investigate non-orthogonal uplink pilot designs for improving the area spectral efficiency
in the downlink of TDD reciprocity-based massive MIMO cellular networks. In particular, we …

We have studied entropic uncertainty relation for two types of quantum measurements in
quantum information theory. One of them is the projective measurements that are …

Cellular networks of massive MIMO base-stations employing TDD/OFDM and relying on
uplink training for both downlink and uplink transmission are viewed as an attractive …
