Summary:

One of the long-promised benefits of quantum computers is simulating molecules very quickly, but it turns out that these extra-fast speeds might not be possible

By Alex Wilkins An artist’s impression of a quantum computerBartlomiej K. Wroblewski/Shutterstock Quantum computers may not be able to simulate molecules and solve other problems in chemistry as fast as researchers had hoped, a new analysis has found. The promise of quantum computers is that they can solve some tasks exponentially faster than ordinary computers, but this hasn’t yet been demonstrated for useful, real-world problems. Physics experiments that changed the world Suzie Sheehy at New Scientist Live this October One highly anticipated application is calculating the energy levels of molecules, an important task in chemistry. …
