A monolithic platform built to push the physical limits of intelligence
We spent the last decade rethinking AI hardware from first principles. Our unique approach combines the advantages of three key technologies: semiconductors, superconductors, and photonics.
Superconductors for computation
Superconducting electronic devices such as Josephson junctions have unparalleled speed and energy efficiency. These devices exhibit ideal properties for the computations that support AI.
Photonics for communication
Neurons in the brain make thousands of connections. Reaching that level of connectivity with electronics is infeasible. Photonic communication makes it possible. Using multi-planar photonic waveguides on wafers and fiber coupling between wafers, we avoid the communication bottlenecks experienced by conventional neural networks.
Semiconductors for integration
Silicon transistors and compound-semiconductor light sources bridge the gap between electrons and photons. In Great Sky's hardware, semiconductor circuitry provides a versatile system for many functions including control logic, amplification, light emission, and more. Transistors and light-emitting diodes play a vital role in our approach.
