A quantum computer slowed simulated molecular quantum effects by a billion times, allowing researchers to directly measure them for the first time. Researchers at Duke University have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with

, vision, and photocatalysis. It is also an example of how advances in quantum computing are being used to investigate fundamental science.“As soon as quantum chemists ran into these conical intersection phenomena, the mathematical theory said that there were certain molecular arrangements that could not be reached from one to the other,” said Kenneth Brown, the Michael J. Fitzpatrick Distinguished Professor of Engineering at Duke.
However, due to a mathematical quirk in the system that emerges from the underlying mathematics, called a geometric phase, certain molecular transformations can’t happen. The blanket can’t wrap entirely around the mountain.

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.
