Firstly I'm not convinced that the photonic version would be more efficient than the all-electric version. The conversion is very expensive. Secondly, they don't need to be on the same chip. The Sha3 chip would be very dense, and the multiplex in time and frequency into the photonic circuit, which would have much larger features, probably printed on silica.
- Mdubrov 5y agoAre you familiar with silicon photonics? (though indeed they probably would not be on the same chip as we point out in the BIP) We have a short primer on Si photonics in our paper actually https://assets.pubpub.org/xi9h9rps/01581688887859.pdf https://assets.pubpub.org/xi9h9rps/01581688887859.pdf
