A beginners look into the large impact quantum computers will have on chemistry. "...With only about a hundred reliable quantum bits, one could model the process by which bacteria produce fertilizer at room temperature" This feat is not possible with our current computing power.
Quantum computers show potential to revolutionize chemistry
Chemical reactions are inherently quantum themselves -- the team actually used a quote from Richard Feynman saying "nature isn't classical, dammit." The problem is that "molecular systems form highly entangled quantum superposition states, which require many classical computing resources in order to represent sufficiently high precision," according to the Google Research blog.
