Quantum Computer Unveils Atomic Dynamics of Light-Sensitive Molecules

Researchers at Duke University have used a quantum simulator, developed from research in quantum computing, to observe a quantum effect known as a conical intersection in light-absorbing molecules. This effect governs the motion of electrons between energy states and has implications for processes such as photosynthesis and vision. By slowing down the simulated molecular quantum effects by a billion times, the researchers were able to directly measure the geometric phase, a mathematical constraint that determines certain molecular transformations. The results provide insights into the inner workings of complex quantum systems and demonstrate the potential of quantum computers in investigating fundamental science.

Quantum Device Slows Simulated Chemical Reaction by 100 Billion Times

Scientists at the University of Sydney have used a quantum computer to slow down a chemical reaction by a factor of 100 billion times, allowing them to directly observe and study a process critical in chemical reactions called a "conical intersection." This breakthrough could have implications for materials science, drug design, and solar energy harvesting, as well as improving our understanding of processes like smog formation and ozone layer damage. The experiment involved mapping the complex problem onto a trapped-ion quantum computer, enabling the researchers to observe and measure the dynamics of the chemical reaction in a way that has never been done before.
