One of the most widely known building blocks of modern physics is Heisenberg's
indeterminacy principle. Among the different statements of this fundamental property of the …

At the beginning of the previous century, Newtonian mechanics was advanced by two new
revolutionary theories, Quantum Mechanics (QM) and General Relativity (GR). Both theories …

We show that two quantities in quantum metrology that were thought to be the same, the
quantum Fisher information matrix and the Bures metric, are not the same. They differ at …

We cast observable measure of quantum coherence as a resource to control the quantum
speed limit (QSL) for unitary evolutions. For non-unitary evolutions, QSL depends on that of …

Quantum metrology studies the ultimate precision limit of physical quantities by using
quantum strategy. In this paper we apply the quantum metrology technologies to the …

We investigate the ultimate estimation precision, characterized by the quantum Fisher
information, of a two-level atom as a detector which is coupled to massless scalar field in the …

The quantum coherence of a multipartite system is investigated when some of the parties
are moving with uniform acceleration and the analysis is carried out using the single-mode …

The projective measurements on a vacuum performed by Rob, who hovers near the event
horizon of the Einstein–Gauss–Bonnet black hole, will result in an entangled state for Alice …

A bstract Relativistic quantum metrology studies the maximal achievable precision for
estimating a physical quantity when both quantum and relativistic effects are taken into …

Herein, we propose a novel strategy for implementing a direct readout of the symmetric
characteristic function of the quantum states of quantum fields without the involvement of …
