In this paper, we provide the first efficient algorithm for port-based teleportation, a unitarily
equivariant version of teleportation useful for constructing programmable quantum …

In this work, we investigate the joint measurability of quantum effects and connect it to the
study of free spectrahedra. Free spectrahedra typically arise as matricial relaxations of linear …

In this manuscript we analyse generalised port-based teleportation (PBT) schemes, allowing
for transmitting more than one unknown quantum state (or a composite quantum state) in …

Quantum cloning is a fundamental protocol of quantum information theory. Perfect universal
quantum cloning is prohibited by the laws of quantum mechanics, only imperfect copies …

The integral formulae over the unitary group $\unitary {d} $ are reviewed with new results
and new proofs. The normalization and the bi-invariance of the uniform Haar measure play …

Herein we continue the study of the representation theory of the algebra of permutation
operators acting on the $ n $-fold tensor product space, partially transposed on the last …

In this work, we establish the connection between the study of free spectrahedra and the
compatibility of quantum measurements with an arbitrary number of outcomes. This …

We introduce the notion of compatibility dimension for a set of quantum measurements: it is
the largest dimension of a Hilbert space on which the given measurements are compatible …

We consider the problem of determining the achievable region of the universal 1 → 2 1→ 2
asymmetric quantum cloning problem. This concerns the quantum cloning of any quantum …
