The major objective of QUANTUM is the investigation of typical quantum mechanical effects and phenomena via three major, interrelated avenues:<\/span><\/p>\n<ul style=\"list-style-type: disc\">\n<li><span style=\"font-family: Open Sans\">Entanglement and other Quantum Correlations,<\/span><\/li>\n<li><span style=\"font-family: Open Sans\">Quantum Simulation, and<\/span><\/li>\n<li><span style=\"font-family: Open Sans\">Theory of Quantum Control.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-family: Open Sans\">Common research themes include the links of entanglement with complexity and information theory, its key role in quantum phase transitions, and the analysis of many-body systems. In addition; the field of quantum simulations, with ground-breaking applications to high-energy physics, lattice gauge theories, many-body systems, and quantum field theories; the development of new measurement and control techniques for open quantum systems, requires strategies to improve the efficiency of thermodynamics processes at the quantum scale, sub-shot-noise imaging and quantum metrology. The theoretical effort is interdisciplinary and highly synergic, involving close collaborations among the partners, exchange of students, post-docs and young researchers, and the use of analytical techniques and numerical methods from quantum field theory, statistical mechanics and quantum information theory. <\/span><\/p>\n<p class=\"pdq2pgselectionanchorcontainer\"><span style=\"font-family: &apos;Open Sans&apos;\"><strong><span style=\"color: black\">Quantum simulations<\/span><\/strong><\/span><\/p>\n<p><span style=\"color: black;font-family: &apos;Open Sans&apos;\">We work on quantum simulation protocols for Abelian and non-Abelian lattice field theories, addressing the preparation of specific excitations, including low-energy and\/or topological states, as well as their real-time dynamics. These problems are first benchmarked using quantum-inspired numerical techniques and then tackled through both analog and digital quantum simulations, designed with specific NISQ devices in mind, mainly based on atomic and superconducting technologies.<\/span><\/p>\n<p><span style=\"color: black;font-family: &apos;Open Sans&apos;\">We also provide theoretical benchmarks and optimal configurations for the quantum simulation of many-body Hamiltonians across different platforms, ranging from Fermi-Fermi and Bose-Fermi mixtures to coherently driven atomic systems.<\/span><\/p>\n<p><span style=\"font-family: &apos;Open Sans&apos;\"><strong><span style=\"color: black\">Entanglement and quantum resources<\/span><\/strong><\/span><\/p>\n<p><span style=\"color: black;font-family: &apos;Open Sans&apos;\">We analyze the interplay between quantum entanglement and other quantum resources that are becoming increasingly relevant in many-body quantum physics. In particular, we explore the relationship between entanglement and so-called nonstabilizerness, or quantum magic, as well as non-Gaussianity and quantum asymmetry.<\/span><\/p>\n<p><span style=\"color: black;font-family: &apos;Open Sans&apos;\">These resources are studied in different contexts, both in and out of equilibrium, and their relevance for diagnosing phase transitions in a broad sense is also investigated. These results also guide the development of methods for quantum simulations, both in the context of Clifford-augmented matrix product states and digital algorithms.<\/span><\/p>\n<p>\u00a0<\/p>\n<p><span style=\"font-family: &apos;Open Sans&apos;\"><em><strong>Staff:<\/strong><\/em> Marcello Dalmonte, Cristian Degli Esposti Boschi, Elisa Ercolessi, Alfredo Iorio, Michele Mazzoni, Piebiagio Pieri, Lorenzo Piroli<\/span><\/p>\n<p><em><strong><span style=\"font-family: &apos;Open Sans&apos;\">Post-Doc: <\/span><\/strong><\/em><span style=\"font-family: &apos;Open Sans&apos;\">Michele Mazzoni, Leonardo Pisani, David Gyorgy Szasz-Schgrin<\/span><\/p>\n<p><span style=\"font-family: &apos;Open Sans&apos;\"><em><strong>PhD students:\u00a0<\/strong> <\/em>Juan Pablo Bayona Pena, Pietro Bovini, Marko Brnovic, Matteo Grotti,\u00a0 David Aram Korbany, Francesco Pirolo, Jinghao Wang<\/span><\/p>\n<p>\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\"><\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button is-style-outline is-style-outline--2\"><a class=\"wp-block-button__link has-very-dark-gray-color has-text-color has-background wp-element-button\" href=\"https:\/\/web.infn.it\/CSN4\/IS\/Linea4\/QUANTUM\/QUANTUM.html\" style=\"background-color:#59abce\" data-wpel-link=\"external\" target=\"_blank\" rel=\"nofollow external noopener noreferrer\" title=\"Open page in new tab National website\">National website<\/a><\/div>\n\n\n\n<div class=\"wp-block-button is-style-outline is-style-outline--3\"><a class=\"wp-block-button__link has-background wp-element-button\" href=\"https:\/\/physics-astronomy.unibo.it\/en\/research\/projects-and-research-lines\/research-lines\/research-line-in-theoretical-physics\/quantum-many-body-systems-and-quantum-information\" style=\"background-color:#59abce\" data-wpel-link=\"external\" target=\"_blank\" rel=\"nofollow external noopener noreferrer\" title=\"Open page in new tab Research @DIFA\">Research @DIFA<\/a><\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>QUANTUM FINITE AND INFINITE QUANTUM &nbsp;SYSTEMS Entanglement, Coherence and Control Local coordinator: Elisa Ercolessi &nbsp;e-mail: elisa.ercolessi@bo.infn.it The INFN Research Network (Iniziativa Specifica) QUANTUM involves 10 research groups: Bari, Bologna, Camerino, Catania, Palermo, Milano (Como), Napoli, Salerno, Padova and Trieste, affiliated with 7 INFN theory divisions: Bari, Bologna, Catania, Milano, Napoli, Padova and Trieste.
