Scientists at the University of Sydney have, for the first time, used a quantum computer to engineer and directly observe a process critical in chemical reactions by slowing it down by a factor of 100 billion times.
"It could also help improve other processes that rely on molecules interacting with light, such as how smog is created or how the ozone layer is damaged."
Chemists have tried to directly observe such geometric processes in chemical dynamics since the 1950s, but it is not feasible to observe them directly given the extremely rapid timescales involved. "Our experiment wasn't a digital approximation of the process—this was a direct analog observation of the quantum dynamics unfolding at a speed we could observe," he said.such as photosynthesis, by which plants get their energy from the sun, molecules transfer energy at lightning speed, forming areas of exchange known as conical intersections.
