Realistic quantum mechanical systems are always exposed to an external environment. This
often induces Markovian processes in which the system loses information to its …

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 …

Revivals of quantum correlations in composite open quantum systems are a useful
dynamical feature against detrimental effects of the environment. Their occurrence is …

Non-Markovian processes have recently become a central topic in the study of open
quantum systems. We realize experimentally non-Markovian decoherence processes of …

Motivated by entanglement protection, our work utilizes a resonance effect to enhance
optomechanical entanglement in the coherent-state representation. We propose a filtering …

We consider two entangled qubits, each of which is coupled to its own reservoir, so that their
entanglement degrades with time. To enhance the qubits' entanglement at a time during the …

We experimentally investigate the dynamics of classical and quantum correlations of a Bell
diagonal state in a non-Markovian dephasing environment. The sudden transition from a …

We present the experimental realization of the optimal estimation protocol for a Pauli noisy
channel. The method is based on the generation of 2-qubit Bell states and the introduction of …

We investigate the generation of entanglement between two noninteracting qubits coupled
to a common reservoir. An experimental setup was conceived to encode one qubit on the …

We study entanglement degradation when one share of an entangled pair experiences
noise. We consider the dissipative Landau-Zener model for describing local noise. The …
