Probabilistic and approximate universal quantum purification machines
Zoe G. del Toro, Jessica Bavaresco
We study the task of lifting arbitrary quantum states and channels to purifications and Stinespring dilations, respectively, in both the probabilistic exact and deterministic appro…
The minimal example of quantum network Bell nonlocality
Erwan Don, Jessica Bavaresco, Patryk Lipka-Bartosik +3
In recent years, the study of Bell nonlocality has been generalized to quantum networks, where multiple independent sources distribute physical systems to distant parties who perfo…
Strategy optimization for Bayesian quantum parameter estimation with finite copies: Adaptive greedy, parallel, sequential, and general strategies
Erik L. André, Jessica Bavaresco, Mohammad Mehboudi
In this work, we study Bayesian quantum parameter estimation given a finite number of uses of the process encoding one or more unknown physical quantities. We analyze the performan…
The power of quantum catalytic local operations
Patryk Lipka-Bartosik, Jessica Bavaresco, Nicolas Brunner +1
A key result in entanglement theory is that the addition of a catalyst dramatically enlarges the set of possible state transformations via local operations and classical communicat…
Catalytic Activation of Bell Nonlocality
Jessica Bavaresco, Nicolas Brunner, Antoine Girardin +2
The correlations of certain entangled states can be perfectly simulated classically via a local model. Hence such states are termed Bell local, as they cannot lead to Bell inequali…
Indefinite causal order in boxworld theories
Jessica Bavaresco, Ämin Baumeler, Yelena Guryanova +1
An astonishing feature of higher-order quantum theory is that it can accommodate indefinite causal order. In the simplest bipartite setting, there exist signaling correlations for…
Designing optimal protocols in Bayesian quantum parameter estimation with higher-order operations
Jessica Bavaresco, Patryk Lipka-Bartosik, Pavel Sekatski +1
Using quantum systems as sensors or probes has been shown to greatly improve the precision of parameter estimation by exploiting unique quantum features such as entanglement. A maj…
Semi-device-independent certification of indefinite causal order in a photonic quantum switch
Huan Cao, Jessica Bavaresco, Ning-Ning Wang +7
We report an experimental certification of indefinite causal order that relies only on the characterization of the operations of a single party. We do so in the semi-device-indepen…
