Quantum computers [1–4] are explicitly quantum mechanical systems that use phenomena
such as superposition and entanglement to perform computational tasks more efficiently …

Nonclassical correlations play a crucial role in the development of quantum information
science. The recent discovery that nonclassical correlations can be present even in …

Quantum algorithms are known for providing more efficient solutions to certain
computational tasks than any corresponding classical algorithm. Here we show that a single …

Nuclear magnetic resonance is arguably both the best available quantum technology for
implementing simple quantum computing experiments and the worst technology for building …

Correlations in quantum systems exhibit a rich phenomenology under the effect of various
sources of noise. We investigate theoretically and experimentally the dynamics of quantum …

One of the milestones of quantum mechanics is Bohr's complementarity principle. It states
that a single quantum can exhibit a particlelike ora wavelike behavior, but never both at the …

The quantification of quantum correlations (other than entanglement) usually entails labored
numerical optimization procedures also demanding quantum state tomographic methods …

We report the experimental measurement of bipartite quantum correlations of an unknown
two-qubit state. Using a liquid state Nuclear Magnetic Resonance setup and employing …

The existence of quantum correlation (as revealed by quantum discord), other than
entanglement and its role in quantum-information processing (QIP), is a current subject for …

Understanding the interplay between quantum coherence and non-Hermitian features
would enable the devising of quantum technologies based on dissipative systems. In turn …
