Deviations from classical physics when distant quantum systems become correlated are interesting both fundamentally and operationally. There exist situations where the correlations enable collaborative tasks that are impossible within the classical formalism. Here, we consider the efficiency of quantum computation protocols compared to classical ones as a benchmark for separating quantum and classical resources and argue that the computational advantage of collaborative quantum protocols in the…

Generalized Quantum Correlations in Discrete Variable Systems
This chapter deals with the development of the novel notion of generalized quantum correlations within discrete variable systems through a toy model and defines the notion of quantum correlations and provides analysis of its feasibility and operational significance.
Classical evolution in quantum systems
For studying quantum phenomena in time, it is vital to have a profound understanding of the classical dynamics. For this reason, we derive equations of motions describing the classical propagation of
Time dynamics of quantum coherence and monogamy in a non-Markovian environment
The local coherence is found to be much more robust under the environmental coupling due to an effective smaller coupling to the reservoir, allowing for a characterization of a quantum state in terms of a coherence tuple on a multipartite state simply by examining various combinations of reservoir couplings.
Benchmarking the Future-Proofedness of Photonic Quantum Systems
This experimental contribution benchmarks the time-multiplexing framework that includes a high-performance source of multi-photon states and a large multiplexing network, together with unique detectors with high photon-number resolution, readily available for distributing quantum light and measuring complex quantum correlations.

Werner derivatives are a special kind of mixing states that originate from the Werner state due to unitary evolutions. In this paper, quantum correlation (QC) swapping between two Werner derivatives
Quantum coherence measurement of qudit systems using three-dimensional photonic circuits
Knowing that quantum coherence plays a central role in quantum phenomena, we propose, in this work, three-dimensional photonic circuits with compact designs that allow measurement of the quantum
Properties of Pancharatnam Phase and Entanglement of a Five-Level Atom Interacting with a Squeezed Field
We introduce a quantum scheme where a single five-level atom interacts with a single-mode cavity field by a time-dependent coupling. During the interaction, the temporal behavior of the quantum
Nonreciprocal single-photon router in quantum networks
High-efficiency single-photon routing of photon signals between different quantum channels is of great importance for the quantum networks with the ability to coherently transfer quantum states
Quantum correlations for anonymous metrology
It is shown that quantum correlations are resources for this task when Alice and Bob do not trust the devices in their labs, and different kinds of quantum correlations according to the level of desired security are distinguished.


Quantum Correlations in Nonlocal BosonSampling
This work reports on a distributed quantum computation protocol in which the input and output quantum states are considered to be classically correlated in quantum informatics, and shows that the correlations between the outcomes of the measurements on the output state cannot be efficiently simulated using classical algorithms.
Experimental quantum computing without entanglement.
The results show that even fully separable, highly mixed, states can contain intrinsically quantum mechanical correlations and that these could offer a valuable resource for quantum information technologies.
Converting Coherence to Quantum Correlations.
It is shown how the interplay between quantum coherence consumption and creation of quantum discord works in the preparation of multipartite quantum correlated states and in the model of deterministic quantum computation with one qubit.
The classical-quantum boundary for correlations: Discord and related measures
One of the best signatures of nonclassicality in a quantum system is the existence of correlations that have no classical counterpart. Different methods for quantifying the quantum and classical
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
Quantum correlations in composite systems
We study emerging notions of quantum correlations in compound systems. Based on different definitions of quantumness in individual subsystems, we investigate how they extend to the joint description
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.
Role of entanglement and correlations in mixed-state quantum computation
In a quantum computation with pure states, the generation of large amounts of entanglement is known to be necessary for a speedup with respect to classical computations. However, examples of quantum
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.
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
