Monogamy relations of quantum coherence between multiple subspaces
Tristan Kraft, Marco Piani
Quantum coherence plays an important role in quantum information protocols that provide an advantage over classical information processing. The amount of coherence that can exist b…
Complete extension: the non-signaling analog of quantum purification
Marek Winczewski, Tamoghna Das, John H. Selby +5
Deriving quantum mechanics from information-theoretic postulates is a recent research direction taken, in part, with the view of finding a beyond-quantum theory; once the postulate…
Simulating the out-of-equilibrium dynamics of local observables by trading entanglement for mixture
Jacopo Surace, Marco Piani, Luca Tagliacozzo
The fact that the computational cost of simulating a many-body quantum system on a computer increases with the amount of entanglement has been considered as the major bottleneck fo…
More entanglement implies higher performance in tailored channel discrimination tasks
Joonwoo Bae, Dariusz Chruściński, Marco Piani
We show that every entangled state provides an advantage in bi- and multi-channel discrimination that singles out its degree of entanglement, quantified in terms of its Schmidt num…
Correlation-assisted process tomography
Matteo Caiaffa, Marco Piani
Standard quantum process tomography on a -dimensional input is performed by preparing several states of an input probe that then evolve under the action of the quantum channel c…
Generic emergence of objectivity of observables in infinite dimensions
Paul A. Knott, Tommaso Tufarelli, Marco Piani +1
Quantum Darwinism posits that information becomes objective whenever multiple observers indirectly probe a quantum system by each measuring a fraction of the environment. It was re…
