Error convergence of quantum linear system solvers
Matias Ginzburg, Ugo Marzolino
We analyze the performance of the Harrow-Hassidim-Lloyd algorithm (HHL algorithm) for solving linear problems and of a variant of this algorithm (HHL variant) commonly encountered…
Precision magnetometry exploiting excited state quantum phase transitions
Qian Wang, Ugo Marzolino
Critical behaviour in phase transitions is a resource for enhanced precision metrology. The reason is that the function, known as Fisher information, is superextensive at critical…
Locality and entanglement of indistinguishable particles
Till Jonas Frederick Johann, Ugo Marzolino
Entanglement is one of the strongest quantum correlation, and is a key ingredient in fundamental aspects of quantum mechanics and a resource for quantum technologies. While entangl…
Entanglement and non-locality in quantum protocols with identical particles
Fabio Benatti, Roberto Floreanini, Ugo Marzolino
We study the role of entanglement and non-locality in quantum protocols that make use of systems of identical particles. Unlike in the case of distinguishable particles, the notion…
Entanglement in indistinguishable particle systems
F. Benatti, R. Floreanini, F. Franchini +1
For systems consisting of distinguishable particles, there exists an agreed upon notion of entanglement which is fundamentally based on the possibility of addressing individually e…
Remarks on entanglement and identical particles
F. Benatti, R. Floreanini, F. Franchini +1
We argue that in the case of identical particles the most natural identification of separability, that is of absence of non-classical correlations, is via the factorization of mean…
