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

In the quantum-Bayesian interpretation of quantum theory (or QBism), the Born rule cannot
be interpreted as a rule for setting measurement-outcome probabilities from an objective …

The capability to generate and manipulate quantum states in high-dimensional Hilbert
spaces is a crucial step for the development of quantum technologies, from quantum …

We investigate correlations among complementary observables. In particular, we show how
to take advantage of mutually unbiased bases for the efficient detection of entanglement in …

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 …

Mutually unbiased bases (MUBs) play a key role in many protocols in quantum science,
such as quantum key distribution. However, defining MUBs for arbitrary high-dimensional …

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 …

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

Mutually unbiased bases (MUBs) provide a standard tool in the verification of quantum
states, especially when harnessing a complete set for optimal quantum state tomography. In …

We study an unextendible maximally entangled basis in arbitrary bipartite spaces. A
systematic way of constructing a set of d 2 orthonormal maximally entangled states in C d⨂ …
