One of the fundamental features of quantum mechanics is the superposition principle, a
manifestation of which is embodied in quantum coherence. Coherence of a quantum state is …

Coherence is a fundamental ingredient in quantum physics and a key resource in quantum
information processing. The quantification of quantum coherence is of great importance. We …

Quantum coherence quantifies the amount of superposition in a quantum system, and is the
reason and resource behind several phenomena and technologies. It depends on the …

We consider the average quantum coherences of typical redits and qudits—vectors of real
and complex Hilbert spaces—with the analytical forms stemming from the symmetry of Haar …

We present a genuine coherence measure based on a quasi-relative entropy as a difference
between quasi-entropies of the dephased and the original states. The measure satisfies non …

Several ways have been proposed in the literature to define a coherence measure based on
Tsallis relative entropy. One of them is defined as a distance between a state and a set of …

We analyze the entanglement, quantum coherence, and shared purity of several manybody
systems. We study the entanglement properties of bipartite and tripartite random quantum …
