One of the greatest challenges in the fields of quantum information processing and quantum
technologies is the detailed coherent control over each and every constituent of quantum …

Multiparticle entanglement leads to richer correlations than two-particle entanglement and
gives rise to striking contradictions with local realism, inequivalent classes of entanglement …

Using the highly entangled six-qubit genuine state we present a quantum private
comparison (QPC) protocol, which enables two users to compare the equality of two bits of …

Randomized measurements constitute a simple measurement primitive that exploits the
information encoded in the outcome statistics of samples of local quantum measurements …

We construct time-dependent optimal control pulses based on a multipartite entanglement
measure as the target functional. The control Hamiltonian is given purely algebraically and …

The robustness of multipartite entanglement of systems undergoing decoherence is of
central importance to the area of quantum information. Its characterization depends …

We investigate the robustness of genuine multiparticle entanglement under decoherence.
We consider different kinds of entangled three-and four-qubit states as well as random pure …

Genuine multipartite entanglement of a quantum system can be partially destroyed by local
decoherence. Is it possible to retrieve the entanglement to some extent by a single local …

We study dynamics of genuine entanglement for quantum states of three and four qubits
under non-Markovian dephasing. Using a computable entanglement monotone for …

In natural light harvesting systems, the sequential quantum events of photon absorption by
specialized biological antenna complexes, charge separation, exciton formation and energy …
