The Asymmetric Quantum Cloning Region
Ion Nechita, Clément Pellegrini, Denis Rochette
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 bei…
Estimating the entanglement of random multipartite quantum states
Khurshed P. Fitter, Cecilia Lancien, Ion Nechita
Genuine multipartite entanglement of a given multipartite pure quantum state can be quantified through its geometric measure of entanglement, which, up to logarithms, is simply the…
Ergodic theory of diagonal orthogonal covariant quantum channels
Satvik Singh, Nilanjana Datta, Ion Nechita
We analyze the ergodic properties of quantum channels that are covariant with respect to diagonal orthogonal transformations. We prove that the ergodic behaviour of a channel in th…
A Fisher information-based incompatibility criterion for quantum channels
Qing-Hua Zhang, Ion Nechita
We introduce a new incompatibility criterion for quantum channels, based on the notion of (quantum) Fisher information. Our construction is based on a similar criterion for quantum…
A tensor norm approach to quantum compatibility
Andreas Bluhm, Ion Nechita
Measurement incompatibility is one of the most striking examples of how quantum physics is different from classical physics. Two measurements are incompatible if they cannot arise…
Order preserving maps on quantum measurements
Teiko Heinosaari, Maria Anastasia Jivulescu, Ion Nechita
We study the partially ordered set of equivalence classes of quantum measurements endowed with the post-processing partial order. The post-processing order is fundamental as it ena…
