Strong polygamy and monogamy relations for multipartite quantum systems
- PhysicsQuantum Inf. Process.
- 2020
This work investigates the monogamy and polygamy relations satisfied by all quantum correlation measures for arbitrary multipartite quantum states and obtains strong monogamy relations that are better than all the existing ones.
Tighter Constraints of Quantum Correlations Among Multipartite Systems
- Physics
- 2021
We provide a characterization of multipartite systems constraints in terms of quantum correlations. By using the Hamming weight of the binary vectors associated with the subsystems, we give the α th…
Monogamy of Quantum Entanglement
- PhysicsFrontiers in Physics
- 2022
Unlike classical correlation, quantum entanglement cannot be freely shared among many parties. This restricted shareability of entanglement among multi-party systems is known as monogamy of…
Strong entanglement distribution of quantum networks
- PhysicsPhysical Review Research
- 2022
This article shows any connected network consisting of generalized EPR states and GHZ states satisfies strong CKW monogamy inequality in terms of bipartite entanglement measure, and applies the new entanglements distribution relation in entangled networks for getting quantum max-flow min-cut theorem in terms Ofan entropy and Rényi-α entropy.
Tripartite realism-based quantum nonlocality
- PhysicsPhysical Review A
- 2019
From an operational criterion of physical reality, a quantifier of realism-based nonlocality was recently introduced for two-part quantum states. This measure has shown to capture aspects that are…
Geometric quantum discord of Heisenberg model with dissipative terms
- PhysicsScientific Reports
- 2020
This paper studies a system with two interacting qubits described by the Heisenberg model with dissipative terms, and shows that after a long enough period of time, the energy and the intensity of the non-uniform magnetic field do not affect the steady-state.

Effect of a large number of parties on the monogamy of quantum correlations
- Physics
- 2015
Monogamy is a non-classical property that restricts the sharability of quantum correlation among the constituents of a multipartite quantum system. Quantum correlations may satisfy or violate…
Exploring multipartite quantum correlations with the square of quantum discord
- Physics
- 2013
We explore the quantum correlation distribution in multipartite quantum states based on the square of quantum discord (SQD). For tripartite quantum systems, we derive the necessary and sufficient…
Conditions for monogamy of quantum correlations: Greenberger-Horne-Zeilinger versus W states
- Physics
- 2012
Quantum correlations are expected to respect all the conditions required for them to be good measures of quantumness in the bipartite scenario. In a multipartite setting, sharing entanglement between…
Multipartite Gaussian steering: monogamy constraints and quantum cryptography applications
- Computer Science
- 2017
It is proved that a monogamy relation akin to the generalized Coffman-Kundu-Wootters inequality holds quantitatively for a recently introduced measure of Gaussian steering, which pin down the role of multipartite steering for quantum communication.
Monogamy of non-local quantum correlations
- Computer ScienceProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences
- 2008
This work bound the trade-off between AB's and AC's violation of the Clauser–Horne–Shimony–Holt inequality and demonstrates that forcing B and C to be classically correlated prevents A and B from violating certain Bell inequalities, relevant for interactive proof systems and cryptography.
Light Cone-Like Behavior of Quantum Monogamy Score and Multisite Entanglement
- Physics
- 2012
There are two important paradigms for defining quantum correlations in quantum information theory, viz. the information-theoretic and the entanglement-separability ones. We find an analytical…
Generalized Monogamy Relations of Concurrence for N-qubit Systems

We present a new kind of monogamous relations based on concurrence and concurrence of assistance. For $N$-qubit systems $ABC_1...C_{N-2}$, the monogamy relations satisfied by the concurrence of…
Quantum discord: a measure of the quantumness of correlations.
- PhysicsPhysical review letters
- 2002
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.
Monogamy of quantum entanglement and other correlations
- Physics
- 2004
It has been observed by numerous authors that a quantum system being entangled with another one limits its possible entanglement with a third system: this has been dubbed the ``monogamous nature of…
