Mutually unbiased bases for quantum degrees of freedom are central to all theoretical
investigations and practical exploitations of complementary properties. Much is known about …

Quantum many-body systems subjected to unitary evolution with the addition of interspersed
measurements exhibit a variety of dynamical phases that do not occur under pure unitary …

Inorganic nanoparticles are among the most investigated nano-objects nowadays, both in
fundamental science and in various technological applications. In this paper, we describe …

Characterization of quantum dynamics is a fundamental problem in quantum physics and
quantum-information science. Several methods are known which achieve this goal, namely …

We identify five selected open problems in the theory of quantum information, which are
rather simple to formulate, are well studied in the literature, but are technically not easy. As …

Ergodic quantum many-body systems undergoing unitary dynamics evolve towards
increasingly entangled states characterized by an extensive scaling of entanglement …

The secure transfer of information is an important problem in modern telecommunications.
Quantum key distribution (QKD) provides a solution to this problem by using individual …

We present the experimental quantum tomography of 7-and 8-dimensional quantum
systems based on projective measurements in the mutually unbiased basis (MUB-QT). One …

All complex Hadamard matrices in dimensions two to five are known. We use this fact to
derive all inequivalent sets of mutually unbiased (MU) bases in low dimensions. We find a …

Recent works have demonstrated that large quantum circuits can be cut and decomposed
into smaller clusters of quantum circuits with fewer qubits that can be executed …
