Coherence in quantum estimation

P Giorda, M Allegra - Journal of Physics A: Mathematical and …, 2017 - iopscience.iop.org
The geometry of quantum states provides a unifying framework for estimation processes
based on quantum probes, and it establishes the ultimate bounds of the achievable …

Characterizing quantum states via sector lengths

N Wyderka, O Gühne - Journal of Physics A: Mathematical and …, 2020 - iopscience.iop.org
Correlations in multiparticle systems are constrained by restrictions from quantum
mechanics. A prominent example for these restrictions are monogamy relations, limiting the …

The complementarity relations of quantum coherence in quantum information processing

F Pan, L Qiu, Z Liu - Scientific Reports, 2017 - nature.com
We establish two complementarity relations for the relative entropy of coherence in quantum
information processing, ie, quantum dense coding and teleportation. We first give an …

Quantum texture and gate identification

F Parisio - arxiv preprint arxiv:2409.06482, 2024 - arxiv.org
We introduce and explore the notion of texture of an arbitrary quantum state, in a selected
basis. In the first part of this work we develop a resource theory and show that state texture is …

Quantum-State Texture and Gate Identification

F Parisio - Physical Review Letters, 2024 - APS
We introduce and explore the notion of texture of an arbitrary quantum state, in a selected
basis. In the first part of this Letter we develop a resource theory and show that state texture …

Average entropy of a subsystem over a global unitary orbit of a mixed bipartite state

L Zhang, H **ang - Quantum Information Processing, 2017 - Springer
We investigate the average entropy of a subsystem within a global unitary orbit of a given
mixed bipartite state in the finite-dimensional space. Without working out the closed-form …
