One-dimensional quantum nanosystems modeled by the Hubbard Hamiltonian exhibit a rich range of physical phenomena, including effects of harmonic confinement and disorder-induced transitions such as Anderson localization. These systems are central to Theoretical Chemistry, Condensed Matter Physics, and Materials Science, with promising applications in quantum nanoscale devices. This projec…
This project aims to explore the role of quantum resources, particularly entanglement and nonstabilizer states, in strongly correlated systems and quantum computation. A key aspect of this proposal is to go beyond entanglement by focusing on nonstabilizer states, which are essential for achieving quantum computational supremacy. While stabilizer states, despite being highly entangled, ca…
Spatial inhomogeneities, such as boundaries, localized impurities, confining potentials and disorder, are natural in realistic nanomaterials. Density Functional Theory (DFT) is a powerful tool for investigating interacting and spatially inhomogeneous nanostructures. Nevertheless the success of the DFT calculations are extremely dependent on the density functionals adopted. In this project…
We propose the construction, optimization and application of density functionals for DFT calculations to investigate superfluidity, entanglement and quantum phase transitions in nanomaterials. Metric spaces and artificial neural networks will be used for testing and optimizing the density functionals. We will refine the metrics space approach and apply it to the study of quantum phase tr…

Confined nanomaterials have attracted great interest both for their technological potential and for their fundamental relevance in Theoretical Chemistry, Condensed Matter Physics, and Materials Science. This project proposes the study of the properties of one-dimensional chains of cold atoms under harmonic confinement, using calculations based on Density Functional Theory (DFT). The syste…
Disordered quantum systems, such as those described by the Hubbard model with random impurities, exhibit complex behavior, including metal-insulator transitions known as Anderson localization. A rigorous theoretical treatment of such systems requires simulations over a very large number of samples, which makes exact methods like DMRG computationally expensive.This project proposes the use…
Advances in the experimental control of atom deposition, enabling the creation of nanostructured materials, have driven the development of quantum devices. To fully explore the potential of these technologies, it is essential to conduct theoretical studies of their properties, requiring methods capable of describing complex systems. Density Functional Theory (DFT) is one of the most effec…

Spatial inhomogeneities are a natural feature of realistic nanomaterials. Not only because of the presence of impurities, confining potentials, interfaces, but also because even the boundaries effects can not be neglected within nanostructures. If on the one hand inhomogeneities are experimentally unavoidable, on the other there exist situations where they are actually desired: for exampl…
In this project we propose to investigate quantum phase transitions in superfluid nanostructures under the perspective of quantum entanglement. We will explore conventional and exotic superfluids via several entanglement measures, between spatial regions and between particles, in the standard and in the extended Hubbard models. Our aim is then to contribute to the understanding of fundam…
By applying density-functional theory calculations within local and non-local approximations via properly designed density functionals we will investigate quantum phase transitions in inhomogeneous nanomaterials. Spatial inhomogeneities are a natural feature of realistic nanostructures, due to boundaries effects, the presence of impurities, confining potentials, interfaces, disorder. In o…

Two-dimensional van der Waals materials offer great opportunities for the development of quantum information science and technology. They serve as hosts of defects for quantum sensing, single-photon emitters, and qubits. Among the most explored van der Waals materials, hexagonal boron nitride (h-BN) stands out due to its large band gap and high structural stability. Point defects in h-BN …
Simulating many-body quantum systems on classical computers is a fundamental challenge in theoretical materials science, particularly in the study of quantum materials with potential applications in emerging technologies. This is due to the exponential growth of the Hilbert space, which encodes complex quantum correlations into the wavefunction - making classical simulations intractable f…
The increasing demand for quantum networks drives research into how different architectures affect stability. One approach is to simulate these systems through electronic interactions and entanglement to evaluate network cohesion. This work employs the one-dimensional Hubbard model to represent qubits with varying property distributions. Additionally, it explores how these properties enha…
This project focuses on enhancing Digitized Adiabatic Quantum Computation (DAQC), a hybrid quantum computing paradigm that combines the strengths of adiabatic quantum algorithms with the flexibility of gate-based circuits. By leveraging classical optimization techniques, we aim to develop a general framework for designing efficient digitized protocols with reduced circuit depth and improv…
