Discovering new drugs and materials by simulating on a quantum computer

Discovering new drugs and materials by simulating on a quantum computer Last year (2017), on September, a team of researchers at IBM have successfully used their quantum computer, IBM Q, to precisely simulate the molecular structure of beryllium hydride (BeH2). It's the most complex molecule ever given the full quantum simulation treatment.Physicists and chemists routinely use computers to simulate how atoms and molecules behave. Such simulations require massive amounts of computing power, because interactions between three or more interacting particles quickly become devilishly complex. But the electrons inside molecules obey the strange laws of quantum mechanics: it’s impossible to simultaneously [...]
