Scientists Freeze Chemical Reaction’s Motion – An Unbelievable Experiment
In a groundbreaking leap in quantum chemistry, scientists have harnessed the power of a quantum computer to witness a commonplace phenomenon unfolding at a mind-boggling 100 billion times slower than its natural pace. This remarkable achievement has unveiled the enigmatic “conical intersection,” a pivotal aspect of quantum chemistry that has long eluded direct observation due to its astonishingly brief timespan, measured in femtoseconds (a minuscule fraction of a quadrillionth of a second).

Researchers from Australia’s University of Sydney and the University of California, San Diego teamed to devise a game-changing approach for extending the duration of this quick encounter. Their innovative approach involves tracking the process by employing a charged particle enclosed within a controlled environment, effectively decelerating it to a more comprehensible timeframe.
Vanessa Olaya Agudelo, a researcher from the University of Sydney’s School of Chemistry, elaborates on this breakthrough, stating, “Utilizing our quantum computer, we engineered a system with the capability to stretch out the chemical dynamics from femtoseconds to milliseconds. This achievement has allowed us to conduct meaningful observations and measurements, a feat that was once deemed unattainable”.
Conical intersections encompass the
rapid exchange of energy between potential energy surfaces within molecules, a phenomenon deeply rooted in the principles of quantum physics, characterized by the convergence of fields and dynamic particle behavior. These quantum reactions hold a pivotal role in various scenarios, including processes like photosynthesis and reactions occurring within the human eye.The uniqueness of this milestone rests in the inventive approach adopted by the scientists. They methodically charted the changes in electron states onto the characteristics of a system using a quantum computer trapping ions. In this configuration, electric fields retained the ions while lasers manipulated them. Following the successful execution of this intricate process, the research team succeeded in slowing down the interaction, enabling direct observation—analogous to studying the aerodynamics of an airplane wing within a wind tunnel.
“Our experiment was not a digital approximation; it was an authentic analogue observation of quantum dynamics unfolding at a perceivable pace,” says Christophe Valahu of the University of Sydney’s School of Physics.
Given the prevalence of conical intersections in photochemistry, this milestone carries substantial promise across a multitude of research domains. It underscores the potential of interdisciplinary cooperation among scientists from diverse fields and underscores the broader capabilities of quantum computers in simulating an extensive range of reactions and interactions.
According to Vanessa Olaya Agudelo, “understanding these fundamental processes occurring within and between molecules opens up new horizons in materials science, drug design and solar energy harnessing.” Furthermore, it has the potential to improve processes involving molecules interacting with light, such as smog generation or ozone depletion.”
