In the realm of quantum walks\, diverse models exist to characterize the b ehavior of quantum particles. This talk will focus on elucidating the most prevalent among them\, including continuous-time\, coined\, Szegedy\, and Staggered Quantum Walks. I will address how they can be classically simul ated and how some simple instances can be executed on real quantum compute rs. I will also highlight some algorithmic applications.\n\nBIO: Franklin Marquezino received his doctoral degree in Computer Modelling from the Na tional Laboratory for Scientific Computing in 2010\, earning the prestigio us CAPES Thesis Award for the best doctoral thesis in the Interdisciplinar y Area across Brazil. Currently\, he is a Visiting Researcher at the Centr e for Quantum Computing Science at the University of Latvia and holds a po sition as an Associate Professor at the Federal University of Rio de Janei ro\, from which he is on temporary leave. Marquezino is a co-author of the book "A Primer on Quantum Computing\," published by Springer\, and serves on the Editorial Board of Theoretical Computer Science\, overseeing artic les in Track C\, "Natural Computation." He remains active in the field of theoretical quantum computing\, with a focus on algorithms and quantum wal ks. His current research seeks to understand the capabilities of quantum p hysics systems in solving computational problems\, with particular interes t in quantum algorithms\, quantum walks\, and their connections to graph t heory.\n\n-----\n\nTITLE: Biasing the quantum vacuum to control macroscop ic probability distributions\, Yannick Salamin\n\nABSTRACT: Quantum fiel d theory reveals that even in the vacuum state\, electromagnetic fields mu st fluctuate\, leading to phenomena such as spontaneous emission\, the Lam b shift\, and the Casimir effect. While these vacuum fluctuations have bee n utilized as a source of perfect randomness\, controlling their probabili ty distribution on photonic platforms has remained elusive. I will present a novel approach to generating biased quantum randomness by injecting vac uum-level bias fields into a multi-stable optical system\, specifically an optical parametric oscillator. By manipulating the probabilities associat ed with the system's output states using bias pulses\, we demonstrate a co ntrollable photonic probabilistic bit. I will delve into the underlying ph ysics of this process and share recent findings that highlight potential a pplications in photonic computing and the sensing of intracavity quantum s tates and weak fields.\n\nBIO: Yannick Salamin is an incoming Assistant Professor in the College of Optics and Photonics (CREOL) at the University of Central Florida (UCF). Previously\, he was a Postdoctoral Fellow at MI T\, where his research focused on complex light-matter interactions in mul tistable and multimodal systems\, with applications in optical computing a nd spectroscopy. Dr. Salamin earned his Dr.Sc. from ETH Zurich\, where he developed integrated plasmonic platforms for efficient nonlinear and optoe lectronic devices. He received the ETH Medal for outstanding thesis\, the 2021 ABB Research Prize\, and was awarded a SNSF Early Post-Doc Mobility f ellowship.
