Right now, people are concerned about global climate models. And global atmospheric submodels. And models of the ocean.
In comes D-Wave Systems, which has developed a Quantum Computer. From their site:
Quantum computers are capable of solving the SE with linear scaling exponentially faster and with exponentially less hardware than conventional computers. For a QC, the difficulty in solving the SE increases by a small, fixed amount for every electron in a system. Even very primitive QCs will be able to outperform supercomputers in simulating nature.
