Modeling and mitigation of cross-talk effects in readout noise with applications to the Quantum Approximate Optimization Algorithm
Filip B. Maciejewski, Flavio Baccari, Zoltán Zimborás +1
We introduce a correlated measurement noise model that can be efficiently described and characterized, and which admits effective noise-mitigation on the level of marginal probabil…
Device-Independent Certification of Genuinely Entangled Subspaces
Flavio Baccari, Remigiusz Augusiak, Ivan Šupić +1
Self-testing is a procedure for characterizing quantum resources with the minimal level of trust. Up to now it has been used as a device-independent certification tool for particul…
Bounding sets of sequential quantum correlations and device-independent randomness certification
Joseph Bowles, Flavio Baccari, Alexia Salavrakos
An important problem in quantum information theory is that of bounding sets of correlations that arise from making local measurements on entangled states of arbitrary dimension. Cu…
Optimization of device-independent witnesses of entanglement depth from two-body correlators
Jordi Tura, Albert Aloy, Flavio Baccari +3
In a recent work [A. Aloy et al. arXiv:1807:06027 (2018)] we have considered the characterization of entanglement depth, from a device-independent perspective, in a quantum many-bo…
Scalable Bell inequalities for qubit graph states and robust self-testing
F. Baccari, R. Augusiak, I. Šupić +2
Bell inequalities constitute a key tool in quantum information theory: they not only allow one to reveal nonlocality in composite quantum systems, but, more importantly, they can b…
Verifying the output of quantum optimizers with ground-state energy lower bounds
Flavio Baccari, Christian Gogolin, Peter Wittek +1
Solving optimisation problems encoded in the ground state of classical-spin systems is a focus area for quantum computing devices, providing upper bounds to the unknown solution. T…
