"Do quantum computers make us what we are?
from New Scientist magazine"

YOUR BODY is teaming with quantum computers. Marching along your DNA and floating around your cells, several hundred million of these minuscule devices are rearranging your molecules in super-efficient quantum fashion.

So, at any rate, says Apoorva Patel, a physicist at the Indian Institute of Science in Bangalore. According to Patel, these weird machines are essential to life. Every living thing from the greatest whale to the lowliest bacterium depends on an army of quantum computers to copy its DNA and put together its proteins.

To many biologists this seems like a bad joke. Received wisdom is that quantum physics, aside from a few minor details, has nothing to do with biology. Sure, it underlies the chemistry of all molecules, including biological ones, but the quantum weirdness is kept well out of sight.
