In this review, the authors introduce the notion of quantum nonclassicality of light and the
role of nonclassicality in optical quantum metrology. The first part of this paper focuses on …

We show that both the classical as well as the quantum definitions of the Fisher information
faithfully identify resourceful quantum states in general quantum resource theories, in the …

Quantum coherence is a basic concept in quantum mechanics, representing one of the most
fundamental characteristics that distinguishes quantum mechanics from classical physics …

Studying quantum properties in solid‐state systems is a significant avenue for research. In
this scenario, double quantum dots appear as a versatile platform for technological …

The optical cat state plays an essential role in quantum computation and quantum
metrology. Here, we experimentally quantify quantum coherence of an optical cat state by …

In this paper, we use the concepts of quantum entanglement and coherence to analyze the
Unruh and anti-Unruh effects based on the model of Unruh–DeWitt detector. For the first …

The past two decades have witnessed a surge of interest in exploring correlation and
coherence measures to investigate quantum phase transitions (QPTs). Here, motivated by …

Since both coherence and quantum correlations arise from the superposition principle and
can be regarded as resources in quantum information tasks, it is of significance to …

Recently, quantum computing and communications rapidly developed to interconnect
heterogeneous quantum devices. In particular, some researchers have been performed …

In this work, the thermal quantum correlations in two coupled double semiconductor charge
qubits are investigated. This is carried out by deriving analytical expressions for both the …
