“Dark and Bright Collective States and the Hidden Energy in Thermal Light”<\/strong><\/p>\n\n\n\n

The bright and dark states\u2014collective mode states that either couple or do not couple to matter\u2014offer new insights into the fundamental aspects of interference with coherent light, providing an alternative explanation for the apparent absence of photons in the dark regions of double- (or multiple-) slit experiments. This reinterpretation opens avenues for further exploration of interference effects and the nature of the light field. A natural question then arises: Could incoherent light also exhibit a decomposition into bright and dark states? The answer is yes, but even more striking is the dominance of dark states: for M modes in thermal light states, the fraction of energy confined to dark states is (M\u20131)\/M, implying that a vast majority of the energy remains inaccessible to direct detection.<\/p>\n\n\n\n

Quo vadis, entanglement? <\/strong><\/p>\n\n\n\n

Entanglement is a quantum phenomenon that is expected to fully unfold in systems composed of multiple qubits. However, creating customized multi-qubit entanglement and exploring its application potential is a formidable challenge. Using single atoms in an optical cavity as a source of triggered photons, we have synthesized a plethora of almost arbitrary entanglement topologies described by graphs. These open the door to a multitude of novel applications such as quantum error correction in photonic quantum computation and quantum communication with tolerance against omnipresent photon loss. <\/p>\n\n\n\n

Atomic Standards of Time and Frequency and timekeeping applications<\/strong>

Time and frequency atomic references have been used as the fundamental standards for several applications in our daily lives. From basic research, aimed at studying fundamental constants, to applications such as geolocation systems, these references are part of our routine in areas that we sometimes do not imagine. This presentation will give an overview of the field, showing a bit of history, the current state-of-the-art and discussing some applications, like remote comparisons, time transfer and their needs and limitations.<\/p>\n\n\n\n

Espectroscopia de Hidrog\u00eanio e Antihidrog\u00eanio: da Mec\u00e2nica Qu\u00e2ntica a QED e al\u00e9m(?).<\/strong><\/p>\n\n\n\n

Fa\u00e7o um passeio pela conex\u00e3o do estudo do \u00e1tomo de hidrog\u00eanio (H) ao desenvolvimento da Mec\u00e2nica Qu\u00e2ntica e aplica\u00e7\u00f5es em nosso conhecimento do Universo. Descrevo experimentos feitos no grupo de Daniel Kleppner na espectroscopia de hidrog\u00eanio aprisionado, um feito que persiste por 30 anos, e que foi um grande impulso \u00e0 pesquisa com antihidrog\u00eanio (anti-H) no CERN. Trago as \u00faltimas not\u00edcias das pesquisas com anti-H no CERN. A an\u00e1lise cega dos \u00faltimos dados por uma teoria recente de forma-de-linha espectral nos permite prever resultados com incerteza em 13 ou 14 algarismos significativos. A extrapola\u00e7\u00e3o do resultado de H (na aus\u00eancia de campo magn\u00e9tico) para nossa armadilha de anti-H na compara\u00e7\u00e3o entre mat\u00e9ria e antimat\u00e9ria \u00e0 partir deste ponto desafia a pr\u00f3pria teoria de QED que precisaria calcular corre\u00e7\u00f5es relativ\u00edsticas de ordem superior. Felizmente, acabamos de realizar uma prova-de-princ\u00edpio, que poderemos fazer espectroscopia de H na mesma armadilha de anti-H, sob as mesmas condi\u00e7\u00f5es. Alguns feitos e hist\u00f3rias de Daniel Kleppner permeiam esta palestra.<\/p>\n\n\n\n

Trapped Ions as a Platform for Quantum Computing and Quantum Networking<\/strong>

Trapped ions are a remarkably versatile physical system that has been widely employed in a variety of applications. Although they are best known for their role in quantum computing, where their long coherence times and individual control allow the realization of high-fidelity quantum gates and complex algorithms, their use extends well beyond computation. The same level of control that enables logical operations also makes trapped ions ideal candidates for precision metrology and quantum sensing. In frequency standards, optical clocks based on trapped ions have achieved fractional uncertainties at the 10\u207b19 level, establishing new frontiers in time and frequency metrology. More recently, trapped ions have gained attention in the context of quantum communication and networking, where researchers have demonstrated entanglement between a trapped ion and a photon, opening the possibility of connecting distant quantum computers through optical links. In this talk, I will present an overview of the many applications of trapped ions, focusing on their use in quantum computing and quantum communication.<\/p>\n\n\n\n

Ultracold molecules for quantum science<\/strong><\/p>\n\n\n\n

The nineteenth century gave birth to not only classical electromagnetic theory, but also laid the groundwork for the development of quantum mechanics. The core of the connection between these two was spectroscopy. The richness of the spectra from both earth-based and astronomical sources was at the same time beautiful and bedeviling. It took development of ideas from both physics and chemistry to begin to make sense of these spectra. Wave resonances and complex structures were part of many models of \u201catoms\u201d, long before the electron was discovered and the development of the Schrodinger equation. Today, we have used spectroscopy to design schemes for single quantum state control over ever more complex quantum systems. We can hold single polyatomic molecules in optical tweezers and have single quantum state control of even symmetric top molecules. Furthermore, entanglement between single molecules is now a reality. I will discuss features of polyatomic molecules that can be used in quantum simulation\/computation and the search for physics beyond the Standard Model. I will discuss our results on the laser cooling of polyatomic molecules into the ultracold regime, including the laser cooling of several different polyatomic species. We realize a tweezer array of single CaOH molecules, a robust MOT and optical dipole trap for SrOH, and one-dimensional laser cooling of CaOCH3<\/sub>. In very recent work we have characterized a new qubit, one composed of parity doublet states in a vibrational bending mode of CaOH. This sets the stage for using SrOH and RaOH for future experiments searching for the electron electric dipole moment, a probe for BSM physics, eventually up to 1000 TeV range, as well as searching for ultralight Dark Matter.<\/p>\n\n\n\n

How Quantum Algorithms Could Shape the Future of Healthcare<\/strong>

In this talk, we will discuss how quantum computing can transform the healthcare field, an area that deals daily with massive volumes of data and complex processing challenges. We will present examples of how quantum computers can accelerate the development of new drugs, as well as emerging applications in quantum optimization and machine learning aimed at medicine and biotechnology. We will also highlight recent results from international research and the role of Brazilian networks and institutes dedicated to quantum information science and technology. The goal is to show that the era of quantum computing applied to healthcare has already begun and that it is urgent to invest in research, innovation, and the training of skilled professionals for this new paradigm.
