Video: A first look inside Google & Nasa's quantum computing lab

Back in May, Google announced the launch of their Quantum Artificial Intelligence Lab: a collaboration with Nasa to "study how quantum computing might advance machine learning." Now, after months of secrecy the search giant has released a video offering a tantalising introduction to the lab and the questions it might one day ask. As the video above says "quantum physics puts everything into question", and if you're expecting quick answers (either from the 6 minute film or from the lab itself) then you will be disappointed. Quantum computing is incredibly difficult, incredibly exciting, and incredibly strange. In the most simplistic terms we can think of normal computers as operating only using 1s and 0s in an either/or state. Quantum computers still use 1s and 0s but they do so in superposition, meaning that the symbols can be both 1 and 0 at the same time as well as every state in between the two.
