- Abstract: Bell inequalities are mathematical constructs that demarcate the boundary
between quantum and classical physics. A new class of multiplicative Bell
inequalities originating from a volume maximization game (based on products of
correlators within bipartite systems) has been recently proposed. For these new
Bell parameters, it is relatively easy to find the classical and quantum, i.e.
Tsirelson, limits. Here, we experimentally test the Tsirelson bounds of these
inequalities using polarisation-entangled photons for different number of
measurements ($n$), each party can perform. For $n=2, 3, 4$, we report the
experimental violation of local hidden variable theories. In addition, we
experimentally compare the results with the parameters obtained from a fully
deterministic strategy, and observe the conjectured nature of the ratio.
Finally, utilizing the principle of "relativistic independence" encapsulating
the locality of uncertainty relations, we theoretically derive and
experimentally test new richer bounds for both the multiplicative and the
additive Bell parameters for $n=2$. Our findings strengthen the correspondence
between local and nonlocal correlations, and may pave the way for empirical
tests of quantum mechanical bounds with inefficient detection systems.

We re-visit the generation and evolution of (Bell) nonlocality in hybrid scenarios whose dynamics is determined by the Jaynes-Cummings Hamiltonian.
Recent results on the optimal Bell violation in qubit-qudit systems show that the nonlocality is much greater than previously estimated.

A simple minimalist argument is given for why some correlations between quantum systems boggle our classical intuition.
The argument relies on two elementary physical assumptions, and recovers the standard experimentally-testable Bell inequality.

We present an experimental realization of recent Bell-type operators designed to provide private random numbers that are secure against adversaries with quantum resources.
We use semi-definite programming to provide lower bounds on the generated randomness in terms of both min-entropy and von Neumann entropy.
Our results demonstrate the first experiment that certifies close to two bits of randomness from binary measurements of two parties.

We experimentally observe the violations of Leggett-Garg-Bell's inequalities on single and multi-qubit systems.
Our analysis highlights the limits of nowadays quantum platforms, showing that the above-mentioned correlation functions deviate from theoretical prediction as the number of qubits and the depth of the circuit grow.

Bell inequalities rest on three fundamental assumptions: realism, locality, and free choice.
We investigate the extent to which a given assumption needs to be relaxed for the other to hold at all costs.
Despite their disparate character, we show that both assumptions are equally costly.

We develop a resource theory of symmetric distinguishability, the fundamental objects of which are elementary quantum information sources.
We study the resource theory for two different classes of free operations: $(i)$ $rmCPTP_A$, which consists of quantum channels acting only on $A$, and $(ii)$ conditional doubly (CDS) maps acting on $XA$.

We study how the probability of presence of a particle is distributed between the two parts of a composite fermionic system.
We prove that it is a non-perturbative property and we find out a large/small coupling constant duality.
Inspired by the proof of KAM theorem, we are able to deal with this problem by introducing a cut-off in energies that eliminates these small denominators.
