Scaling Up the Brain with Stacked Wafers and Superconductors
1:48:53 - 1:57:58 (09:05)
To match the scale of the human brain, wafers need to be stacked on top of each other with fiber optic communication between them, and 10 billion neurons can be achieved in a space the size of a table. Superconducting single photon detectors can offer analog values with up to 10-bit equivalent resolution, and silicon nitride can be used to form rectangle-shaped paths that target subregions of the network.

The use of superconductors in single photon detectors allows for analog values with high resolution, making it possible to communicate with the physical minimum of one photon.

Summary
The use of superconductors in single photon detectors allows for analog values with high resolution, making it possible to communicate with the physical minimum of one photon. The energy of circulating current in superconductors is less than that of the original photon, making it an efficient means of communication.

Summary
To match the number of neurons in the human brain, wafers need to be stacked with fiber optic communication between them, filling a space like a table. Different materials are used to create rectangle branches targeting different regions of the network to form systems with comparable scale to the human brain.
