The extraordinary sensitivity of plasmonic sensors is well-known in the optics and photonics
community. These sensors exploit simultaneously the enhancement and the localization of …

Realizing strong coupling between a single quantum emitter (QE) and an optical cavity is of
crucial importance in the context of various quantum optical applications. Although Rabi …

By using the quantum Fisher information (QFI), we address the process of single-parameter
estimation in the presence of bosonic as well as fermionic environments and protection of …

Using a two-level moving probe, we address the temperature estimation of a static thermal
bath modeled by a massless scalar field prepared in a thermal state. Different couplings of …

We address the estimation of the number of photons and temperature in a micromaser-type
system with Fock state and thermal fields. We analyze the behavior of the quantum Fisher …

We address the dephasing dynamics of the quantum Fisher information for the process of
quantum thermometry with probes coupled to squeezed thermal baths via the nondemolition …

Finding the energy levels of a quantum system is a significant task, for instance, to
characterize the compatibility of materials or to analyze reaction rates in drug discovery and …

We address how the non-local nature of the topological qubits, realized by Majorana modes
and driven by an external magnetic field, can be used to control the non-Markovian …

We address the quantum estimation of parameters encoded into the initial state of two
modes of a Dirac field described by relatively accelerated parties. By using the quantum …

A scheme is proposed to estimate the decay rates of the subsystem in an atom–cavity-
optomechanical system which also is known as the hybrid optomechanical system. Quantum …
