Title: Experimental assessment of non-classicality in a solid-state spin qutrit
Authors: Santiago Hern\'andez-G\'omez, Stefano Gherardini, Alessio Belenchia, Matteo Lostaglio, Amikam Levy, Nicole Fabbri
Abstract summary: Non-classicality, encapsulated by negative quasiprobabilities, has been shown to underlie metrological and thermodynamical advantages. In this work, we use a nitrogen-vacancy center in diamond to realize the experimental implementation of a weak two-point measurement scheme. We experimentally show work extraction, empowered by non-classicality, beyond the classical case.

Abstract: The incompatibility of physical observables is one of the hallmarks of quantum mechanics. This form of non-classicality, encapsulated by negative quasiprobabilities, has been shown to underlie metrological and thermodynamical advantages and it can be related with information scrambling and dynamical phase transitions in many-body systems. In this work, we use a nitrogen-vacancy center in diamond to realize the experimental implementation of a weak two-point measurement scheme to reconstruct the Margenau-Hill quasiprobability distribution, whose negativity implies non-classicality. Finally, we experimentally show work extraction, empowered by non-classicality, beyond the classical case.

Work statistics, quantum signatures and enhanced work extraction in quadratic fermionic models [62.997667081978825]
In quadratic fermionic models we determine a quantum correction to the work statistics after a sudden and a time-dependent driving. Such a correction lies in the non-commutativity of the initial quantum state and the time-dependent Hamiltonian. Thanks to the latter, one can assess the onset of non-classical signatures in the KDQ distribution of work.

Nonclassical correlations in decaying systems [0.0]
Correlations of weak measurements in the noninvasive limit violate the classical bound for a universal class of systems. The phenomenon can be experimentally observed by continuous weak measurements and a large class of observables.

Entanglement dynamics of spins using a few complex trajectories [77.34726150561087]
We consider two spins initially prepared in a product of coherent states and study their entanglement dynamics. We adopt an approach that allowed the derivation of a semiclassical formula for the linear entropy of the reduced density operator.

Identifying nonclassicality from experimental data using artificial neural networks [52.77024349608834]
We train an artificial neural network to classify classical and nonclassical states from their quadrature-measurement distributions. We show that the network is able to correctly identify classical and nonclassical features from real experimental quadrature data for different states of light.

Decoherence effects in non-classicality tests of gravity [0.0]
We study the effects of decoherence on the system's dynamics by monitoring the corresponding degree of entanglement. We find that any value of the parameters of the Continuous Spontaneous localization model would completely hinder the generation of gravitationally induced entanglement.

Experimental certification of nonclassicality via phase-space inequalities [58.720142291102135]
We present the first experimental implementation of the recently introduced phase-space inequalities for nonclassicality certification. We demonstrate the practicality and sensitivity of this approach by studying nonclassicality of a family of noisy and lossy quantum states of light.

Evaluating Single-mode Nonclassicality [0.0]
We apply the measure to evaluate and categorize different classes of nonclassical states. We discover a class of states that can achieve the maximum nonclassicality in the limit of large mean number of excitations. We also discover that the nonclassicality of certain states can be greatly improved with a single-photon addition.

Verifying single-mode nonclassicality beyond negativity in phase space [0.0]
We establish a framework of nonclassicality in phase space that addresses nonclassical states comprehensively. We prove that it detects all nonclassical Gaussian states and all non-Gaussian states of arbitrary dimension remarkably. This approach can be adapted to constitute practical tests in two directions looking into particle and wave nature of bosonic systems.

On the complex behaviour of the density in composite quantum systems [62.997667081978825]
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.

Quantum Zeno effect appears in stages [64.41511459132334]
In the quantum Zeno effect, quantum measurements can block the coherent oscillation of a two level system by freezing its state to one of the measurement eigenstates. We show that the onset of the Zeno regime is marked by a $textitcascade of transitions$ in the system dynamics as the measurement strength is increased.
