Self-testing with dishonest parties and device-independent entanglement certification in quantum networks
Gláucia Murta, Flavio Baccari
Here we consider the task of device-independent certification of the quantum state distributed in a network when some of the nodes in this network may collude and act dishonestly.…
Typical Correlation Length of Sequentially Generated Tensor Network States
Daniel Haag, Flavio Baccari, Georgios Styliaris
The complexity of quantum many-body systems is manifested in the vast diversity of their correlations, making it challenging to distinguish the generic from the atypical features.…
Scalable Bell inequalities for graph states of arbitrary prime local dimension and self-testing
Rafael Santos, Debashis Saha, Flavio Baccari +1
Bell nonlocality -- the existence of quantum correlations that cannot be explained by classical means -- is certainly one of the most striking features of quantum mechanics. Its ra…
Unveiling quantum entanglement in many-body systems from partial information
Irénée Frérot, Flavio Baccari, Antonio Acín
Quantum entanglement is commonly assumed to be a central resource for quantum computing and quantum simulation. Nonetheless, the capability to detect it in many-body systems is sev…
Preparation and verification of tensor network states
Esther Cruz, Flavio Baccari, Jordi Tura +2
We consider a family of tensor network states defined on regular lattices that come with a natural definition of an adiabatic path to prepare them. This family comprises relevant c…
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…
Entanglement marginal problems
Miguel Navascues, Flavio Baccari, Antonio Acin
We consider the entanglement marginal problem, which consists of deciding whether a number of reduced density matrices are compatible with an overall separable quantum state. To ta…
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…
Device-independent witnesses of entanglement depth from two-body correlators
Albert Aloy, Jordi Tura, Flavio Baccari +3
We consider the characterization of entanglement depth in a quantum many-body system from the device-independent perspective; i.e., certifying how many particles are genuinely enta…
Maximal nonlocality from maximal entanglement and mutually unbiased bases, and self-testing of two-qutrit quantum systems
Jędrzej Kaniewski, Ivan Šupić, Jordi Tura +3
Bell inequalities are an important tool in device-independent quantum information processing because their violation can serve as a certificate of relevant quantum properties. Prob…
Bell correlations depth in many-body systems
Flavio Baccari, Jordi Tura, Matteo Fadel +6
While the interest in multipartite nonlocality has grown in recent years, its existence in large quantum systems is difficult to confirm experimentally. This is mostly due to the i…
Efficient device-independent entanglement detection for multipartite systems
Flavio Baccari, Daniel Cavalcanti, Peter Wittek +1
Entanglement is one of the most studied properties of quantum mechanics for its application in quantum information protocols. Nevertheless, detecting the presence of entanglement i…
