Multimode and Long-Lived Quantum Correlations Between Photons and Spins in a Crystal. [PDF]

Physical Review Letters, 2017
The realization of quantum networks and quantum repeaters remains an outstanding challenge in quantum communication. These rely on the entanglement of remote matter systems, which in turn requires the creation of quantum correlations between a single ...

Towards minimal self-testing of qubit states and measurements in prepare-and-measure scenarios

New Journal of Physics
Self-testing is a promising approach to certifying quantum states or measurements. Originally, it relied solely on the outcome statistics of the measurements involved in a device-independent (DI) setup.

How discord underlies the noise resilience of quantum illumination

New Journal of Physics, 2016
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.

Lattice-commensurate skyrmion texture in a centrosymmetric breathing kagome magnet

npj Quantum Materials
Skyrmion lattices (SkL) in centrosymmetric materials typically have a magnetic period on the nanometer-scale, so that the coupling between magnetic superstructures and the underlying crystal lattice cannot be neglected. We reveal the commensurate locking

Quantum coherence and correlations in quantum system [PDF]

Scientific Reports, 2015
AbstractCriteria of measure quantifying quantum coherence, a unique property of quantum system, are proposed recently. In this paper, we first give an uncertainty-like expression relating the coherence and the entropy of quantum system. This finding allows us to discuss the relations between the entanglement and the coherence.

Quantum correlations from simple assumptions

Physical Review A, 2019
We address the problem of deriving the set of quantum correlations for every Bell and Kochen-Specker (KS) contextuality scenario from simple assumptions.
