Professor Christian Roos from the University of Innsbruck will present a seminar on investigating many-body physics using trapped ions dressed by laser light. The talk will cover encoding, manipulating, and entangling quantum information using laser-cooled trapped ions. Recent experiments demonstrating entangling interactions and single-qubit control in strings of up to 50 ions will be discussed. Why it matters: This seminar contributes to advancements in quantum computing and simulation, fields of increasing interest in the Middle East as the region invests in advanced technologies.
Researchers at Abu Dhabi’s Technology Innovation Institute (TII) have identified a new universality in dynamic phase transitions by investigating a "quench" scenario in a two-dimensional atomic cloud undergoing a Kosterlitz-Thouless (BKT) transition. They discovered the universal behavior that vortex pairs form from the fluctuations of the atomic cloud during this dynamic phase transition and successfully described the process using a real-time renormalization method. Their paper, titled “Universal scaling of the dynamic BKT transition in quenched 2D Bose gases”, was published in Science. Why it matters: This discovery could catalyze the development of sensitive quantum sensors and contributes to a better understanding of many-body dynamics.
Researchers from LENS, CNR-INO, the University of Florence, UNAM, RPTU University Kaiserslautern-Landau, and TII Abu Dhabi have observed Shapiro steps in ultracold atoms for the first time. This allows for real-time observation of quantum mechanics and could lead to advanced quantum sensors and simulation. The experiments involved creating vortex-antivortex pairs, resulting in step-like signals, and the findings were published in Science. Why it matters: This breakthrough provides a new method to observe and control quantum coherence, potentially enabling advancements in quantum technologies and simulations within the region.
