We show that the symmetric portion of correlated coherence is always a valid quantifier of entanglement, and that this property is independent of the particular choice of coherence measure. This leads to an infinitely large class of coherence based entanglement monotones, which is always computable for pure states if the coherence measure is also computable. It is already known that every entanglement measure can be constructed as a coherence measure. The results presented here show that the… 

Optimizing nontrivial quantum observables using coherence

In this paper we consider the quantum resources required to maximize the mean values of any nontrivial quantum observable. We show that the task of maximizing the mean value of an observable is

Dynamics of complete complementarity relations under quantum channels

In this article, we study the behavior of complete complementarity relations under the action of some common noisy quantum channels (amplitude damping, phase damping, bit flip, bit-phase flip, phase

Distribution of the Generalized Correlated Coherence in Tripartite Systems

The generalized correlated coherence is not stored locally, but does exist within the correlations between subsystems. We show that, in tripartite quantum systems, the generalized correlated

Operational symmetries of entangled states

Quantum entanglement obscures the notion of local operations; there exist quantum states for which all local actions on one subsystem can be equivalently realized by actions on another. We

Characterizing coherence with quantum observables

We introduce a procedure based on quantum expectation values of measurement observables to characterize quantum coherence. Our measure allows one to quantify coherence without having to perform

Thermal Entanglement and Correlated Coherence in Two Coupled Double Quantum Dots Systems

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 thermal

Coherence of assistance and assisted maximally coherent states

It is shown that the coherence of assistance as well as entanglement of assistance are strictly larger than the coherent of convex roof and entangled states for all full rank density matrices so all fullRank quantum states are distillable in the assisted coherence distillation.

Complete Complementarity Relations in System–environment Decoherent Dynamics

We investigate the system-environment information flow from the point of view of complete complementarity relations. We consider some common noisy quantum channels: amplitude damping, phase damping,

Unification of quantum resources in distributed scenarios

This work extends the single party coherence resource framework to the distributed scenario and relates it to basis-dependent discord, and shows the operational meaning of basis- dependent discord in quantum key distribution.

Additivity of entanglement of formation via an entanglement-breaking space

We study the entanglement-breaking (EB) space, such that the entanglement of formation (EOF) of a bipartite quantum state is additive when its range is an EB subspace. We systematically construct the



Unified view of quantum correlations and quantum coherence

In this paper, we argue that quantum coherence in a bipartite system can be contained either locally or in the correlations between the subsystems. The portion of quantum coherence contained within

Measuring Quantum Coherence with Entanglement.

This work demonstrates the usefulness of the approach by proving that the fidelity-based geometric measure of coherence is a full convex coherence monotone, and deriving a closed formula for it on arbitrary single-qubit states.

Genuine correlated coherence

We introduce a notion of genuine correlated coherence. Such a notion is based on the possibility of concentrating on individual systems the coherence present in a distributed system, by making use of

Relating the Resource Theories of Entanglement and Quantum Coherence.

This Letter analyzes the coherence and entanglement trade-offs in the tasks of state formation and resource distillation and introduces a new LIOCC monotone that completely characterizes a state's optimal rate of bipartite coherence distillation.

Relating quantum coherence and correlations with entropy-based measures

Using entropy-based measures, this paper shows that quantum discord and quantum entanglement can be well characterized by quantum correlated coherence, and proves that theEntanglement measure formulated by quantum correlate coherence is lower and upper bounded by the relative entropy of Entanglement and the entanglements of formation, respectively.

Quantifying the Coherence between Coherent States.

An orthogonalization procedure is detail that allows for the quantification of the amount of coherence present in an arbitrary superposition of coherent states and it is shown that the construction belongs to a family of resource monotones within the framework of a resource theory of linear optics, thus establishing deeper connections between the class of incoherent operations in the finite dimensional regime and linear optical operations inThe continuous variable regime.

Quantum processes which do not use coherence

A major signature of quantum mechanics beyond classical physics is coherence, the existence of superposition states. The recently developed resource theory of quantum coherence allows the

Genuine Distributed Coherence

An entropic quantifier of genuine distributed multipartite coherence for generic mixed states for bipartite pure-state case is defined, and in the latter case necessary and sufficient conditions for the possibility of fully localizing the coherence are derived.

Coherence, quantum Fisher information, superradiance, and entanglement as interconvertible resources

We demonstrate that quantum Fisher information and superradiance can be formulated as coherence measures in accordance with the resource theory of coherence, thus establishing a direct link between

Quantum discord: a measure of the quantumness of correlations.

This work shows that absence of entanglement does not imply classicality, and considers the vanishing of discord as a criterion for the preferred effectively classical states of a system, i.e., the pointer states.
