How discord underlies the noise resilience of quantum illumination
The benefits of entanglement can outlast entanglement itself. In quantum illumination, entanglement is employed to better detect reflecting objects in environments so noisy that all entanglement is destroyed.

Discord and quantum computational resources [PDF]
Discordant states appear in a large number of quantum phenomena and seem to be a good indicator of divergence from classicality. While there is evidence that they are essential for a quantum algorithm to have an advantage over a classical one, their precise role is unclear.

For the linear gold complexes R3PauCl, R = H, Me, Et, immersed in solvent, a dimer aggregation model is required to achieve good agreement between the calculated and experimental absorption spectra using a spin‐orbit/relativistic/solvent model approximation. The solvatochromic effect increases with the dielectric constant up to a saturation point.

Global quantum correlations in finite-size spin chains
We perform an extensive study of the properties of global quantum correlations in finite-size one-dimensional quantum spin models at finite temperature. By adopting a recently proposed measure for global quantum correlations (Rulli and Sarandy 2011 Phys.

Global Quantum Discord in Multipartite Systems
We propose a global measure for quantum correlations in multipartite systems, which is obtained by suitably recasting the quantum discord in terms of relative entropy and local von Neumann measurements.

The effect of 19 substituents on the regioselectivity of Diels–Alder reactions is explored by quantum chemistry. Experimentally observed product distributions are compared favorably with calculated reaction barrier trends. Unlike interaction energies, the deformation energies corresponding to the two regioisomers differ significantly and follow the ...

Geometric measure of quantum discord for entanglement of Dirac fields in noninertial frames
We investigate the geometric measure of quantum discord of all possible bipartite divisions of a tripartite system of Dirac fields in noninertial frames. As a comparison, we calculate the geometric measure of entanglement.

Quantum Correlations in non-Markovian Environments
We have studied the analytical Markovian and non-Markovian dynamics of quantum correlations, such as entanglement, quantum discord and Bell nonlocalities for three noisy qubits.

Quantum computing: The power of discord [PDF]
Physicists have always thought quantum computing is hard because quantum states are incredibly fragile. But could noise and messiness actually help things along?
