Enhanced quantum frequency estimation by nonlinear scrambling
Victor Montenegro, Sara Dornetti, Alessandro Ferraro +1
Frequency estimation, a cornerstone of basic and applied sciences, has been significantly enhanced by quantum sensing strategies. Despite breakthroughs in quantum-enhanced frequenc…
Qubit magic-breaking channels
Ayan Patra, Rivu Gupta, Alessandro Ferraro +1
We develop a notion of quantum channels that can make states useless for universal quantum computation by destroying their magic (non-stabilizerness) - we refer to them as magic-br…
Macroscopic bound entanglement in thermal graph states
D. Cavalcanti, L. Aolita, A. Ferraro +2
We address the presence of bound entanglement in strongly-interacting spin systems at thermal equilibrium. In particular, we consider thermal graph states composed of an arbitrary…
Almost all quantum states have non-classical correlations
A. Ferraro, L. Aolita, D. Cavalcanti +2
Quantum discord quantifies non-classical correlations in a quantum system including those not captured by entanglement. Thus, only states with zero discord exhibit strictly classic…
Local temperature in quantum thermal states
A. Garcia-Saez, A. Ferraro, A. Acin
We consider blocks of quantum spins in a chain at thermal equilibrium, focusing on their properties from a thermodynamical perspective. Whereas in classical systems the temperature…
Three-mode entanglement by interlinked nonlinear interactions in optical media
A. Ferraro, M. G. A. Paris, A. Allevi +3
We address the generation of fully inseparable three-mode entangled states of radiation by interlinked nonlinear interactions in media. We show how three-mode entanglemen…
