Hartmut Neven is a computer scientist who has led several groundbreaking developments for Google, including Google Glass and image-recognition software. Well, okay, Google Glass turned out to be somewhat of a failure.....but I digress.

Neven believes the concept of quantum mechanics supports the theory of parallel universes or "multiverses." Yes, multiversres are common in Marvel comic books but Neven hopes to prove they really exist.

Neven is spearheading Google's effort to build the world's first "quantum computer." Google hopes to be able to demonstrate it in 2018. Other companies, including IBM and Microsoft, are also trying to build such a computer. Here are the details -- and you'll learn new words such as "qubit" and "novemvigintillion."
