Accessible and inaccessible quantum coherence in relativistic quantum systems
Saveetha Harikrishnan, Segar Jambulingam, Peter P. Rohde +1
The quantum coherence of a multipartite system is investigated when some of the parties are moving with uniform acceleration and the analysis is carried out using the single mode a…
Thermal coherence of the Heisenberg model with Dzyaloshinsky-Moriya interactions in an inhomogenous external field
Manikandan Parthasarathy, Segar Jambulingam, Tim Byrnes +1
The quantum coherence of the two-site XYZ model with Dzyaloshinsky-Moriya (DM) interactions in an external inhomogenous magnetic field is studied. The DM interaction, the magnetic…
Time dynamics of quantum coherence and monogamy in a non-Markovian environment
Chandrashekar Radhakrishnan, Po-Wen Chen, Segar Jambulingam +2
The time evolution of the distribution and shareability of quantum coherence of a tripartite system in a non-Markovian environment is examined. The total coherence can be decompose…
Quantum coherence of the Heisenberg spin models with Dzyaloshinsky-Moriya interactions
Chandrashekar Radhakrishnan, Manikandan Parthasarathy, Segar Jambulingam +1
We study quantum coherence in a spin chain with both symmetric exchange and antisymmetric Dzyaloshinsky-Moriya couplings. Quantum coherence is quantified using the recently introdu…
Lorentz invariant entanglement distribution for the space-based quantum network
Tim Byrnes, Batyr Ilyas, Louis Tessler +3
In recent years there has been a great deal of focus on a globe-spanning quantum network, including linked satellites for applications ranging from quantum key distribution to dist…
Distribution of quantum coherence in multipartite systems
R. Chandrashekar, P. Manikandan, J. Segar +1
The distribution of coherence in multipartite systems in examined. We use a new coherence measure with entropic nature and metric properties, based on the quantum Jensen-Shannon di…
