Catalysts open up new reaction pathways that can speed up chemical reactions while not
consuming the catalyst. A similar phenomenon has been discovered in quantum information …

One of the best signatures of nonclassicality in a quantum system is the existence of
correlations that have no classical counterpart. Different methods for quantifying the …

We propose a method for detecting bipartite entanglement in a many-body mixed state
based on estimating moments of the partially transposed density matrix. The estimates are …

Statistical mechanics relies on the maximization of entropy in a system at thermal
equilibrium. However, an isolated quantum many-body system initialized in a pure state …

Quantifying coherence is an essential endeavor for both quantum foundations and quantum
technologies. Here, the robustness of coherence is defined and proven to be a full …

Top quarks have been recently shown to be a promising system to study quantum
information at the highest-energy scale available. The current lines of research mostly …

Top quarks represent unique high-energy systems since their spin correlations can be
measured, thus allowing to study fundamental aspects of quantum mechanics with qubits at …

All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

How can one prove that a given quantum state is entangled? In this paper we review
different methods that have been proposed for entanglement detection. We first explain the …

We provide necessary and sufficient conditions for separability of mixed states of n-particle
systems. The conditions are formulated in terms of maps which are positive on product …
