The coherent superposition of states, in combination with the quantization of observables,
represents one of the most fundamental features that mark the departure of quantum …

Quantum coherence and quantum correlations are of fundamental and practical significance
for the development of quantum mechanics. They are also cornerstones of quantum …

Any quantum resource theory is based on free states and free operations, ie states and
operations which can be created and performed at no cost. In the resource theory of …

The search for a simple description of fundamental physical processes is an important part
of quantum theory. One example for such an abstraction can be found in the distance lab …

We investigate how the classical correlations between successive actions of a colored
dephasing channel affect the decoherence of a two-qubit system. Our calculation shows that …

In quantum mechanics, quantum coherence of a state relative to a quantum measurement
can be identified with the quantumness that has to be destroyed by the measurement. In …

The long-time maintenance of quantum coherence is crucial for its practical applications. We
explore decoherence process of a multiqubit system passing through a correlated channel …

The dynamics of relative entropy and l 1 norm of coherence, as well as, the Wigner-Yanase
skew and quantum Fisher information are studied in the one-dimensional XY spin chain in …

Quantum coherence, which quantifies the superposition properties of a quantum state, plays
an indispensable role in quantum resource theory. A recent theoretical work [Phys. Rev. Lett …

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 …
