Credit: Stefanie Zingsheim/University of Sydney To observe how a wavepacket behaves around a simulated conical intersection, researchers used a single trapped ion – a single charged atom of ytterbium confined in a vacuum by electric fields.The mathematical model that describes conical intersections was then engineered into the trapped-ion system.Researchers then constructed a movie of the ion’s evolution around the conical intersection .
This study slowed down the dynamics in the quantum computer and revealed the tell-tale hallmarks predicted – but never before seen – associated with conical intersections in photochemistry., said: “This exciting result will help us better understand ultrafast dynamics – how molecules change at the fastest timescales.

Quantum computer unveils atomic dynamics of light-sensitive moleculesResearchers have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with incoming photons. Known as a conical intersection, the effect puts limitations on the paths molecules can take to change between different configurations. The observation method makes use of a quantum simulator, developed from research in quantum computing, and offers an example of how advances in quantum computing are being used to investigate fundamental science.

Physicists develop series of quality control tests for quantum computersQuantum technologies—and quantum computers in particular—have the potential to shape the development of technology in the future. Scientists believe that quantum computers will help them solve problems that even the fastest supercomputers are unable to handle yet. Large international IT companies and countries like the United States and China have been making significant investments in the development of this technology. But because quantum computers are based on different laws of physics than conventional computers, laptops, and smartphones, they are more susceptible to malfunction.
