Will this project "emulate" a human brain down to the subatomic level? Down to even the atomic level?
The short answer is that each part of the simulation, from ion channels and synapses to cell bodies to network topologies and cell distributions, is done at the lowest level that people in the laboratories can effectively isolate and study. From that they can derive mathematical models of each part, and integrate those models to simulate them interacting over time and space.
Is it a simplified model of the brain? Yes, but its the most detailed model that science can produce (or at least it aims to be).
how would you even measure the "intelligence" of a simulated brain without any sensory organs or an ability to communicate?
What makes you think that's difficult to simulate? It's been shown that primate brains are capable of learning to interpret novel inputs, such as a grid of electrodes 'painting' an image onto cortex. There was also a study where they implanted electrodes in a monkey's brain where the rate of activation of the cells surrounding the electrodes moved a cursor on a computer screen. The monkey learned to move the cursor.
This shows that simulated inputs and outputs wouldn't have to perfectly correspond with reality in order for the brain to be able to process it.
