Grava, Stefano (Date of defense: 2022-10-28)
(English) The interface between light and cold atomic ensembles is a fundamental platform to unravel the quantum world and develop quantum technological applications. Its success relies on the simple idea that the efficiency ...
Rombaut Segarra, Juan (Date of defense: 2022-07-12)
(English) Highly transparent optical surfaces with anti-reflection (AR) and self-cleaning properties have the potential to increase performance in a wide range of applications, such as display screens, photovoltaic cells ...
Tagliabue, Susanna (Date of defense: 2022-04-29)
(English) In the intensive care, the multimodal monitoring of the patient is crucial. The systemic physiology is routinely and comprehensively monitored but the practical monitoring of the brain is lacking. Hybrid diffuse ...
Abiuso, Paolo (Date of defense: 2022-12-12)
(English) In this thesis, we study the optimization of operational tasks that involve the manipulation of quantum resources. In most cases, such optimizations are aided by understanding the geometric properties of the ...
Scandi, Matteo (Date of defense: 2023-07-13)
(English) The modern understanding of physics is deeply linked with the concept of information. The revival of the study of quantum mechanics in the form of quantum information is just an example of a more general trend ...
Mazzinghi, Chiara (Date of defense: 2023-07-26)
(English) In this work we propose and demonstrate cavity-enhanced polarization rotation to detect magnetic effects in transparent media with greater sensitivity at equal optical disturbance to the atomic medium. We use the ...
Kobayashi Frisk, Lisa (Date of defense: 2023-07-14)
(English) The brain is an organ with a large energy budget compared to its volume and weight and constantly requires oxygen-rich blood to meet its metabolic needs. Given this fact, a tool that enables the continuous ...
Bera, Mohit Lal (Date of defense: 2023-07-28)
(English) n this thesis, our main objective is to utilize different kinds of quantum dynamics as resources. To do so, we investigate thermodynamics, non-equilibrium steady states, and dynamical spectroscopy in order to ...
Barcons Ruiz, David (Date of defense: 2023-07-11)
(English) Graphene has revolutionized the field of condensed matter physics over the last two decades, emerging as an outstanding research platform. This is because graphene electrons behave as massless Dirac fermions, ...
Rakonjac, Jelena Velibor (Date of defense: 2023-06-26)
(English) Future networks for quantum communication will require a new form of technology in order to operate over long distances. The no-cloning theorem precludes the use of amplification, so quantum repeater schemes have ...
Das, Ipsita (Date of defense: 2023-05-24)
(English) The discovery of two dimensional materials opened a unique pathway to study the electronic properties of quantum materials which are otherwise absent in bulk systems. Soon after the discovery of graphene (2004), ...
