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

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.
One highly anticipated application is calculating the energy levels of molecules, an important task in chemistry. …
