tl;dr
TurboQuant is a recent paper from Google and NYU that has gained massive traction in mainstream media and the AI community. As implementations of TurboQuant are integrated into various popular projects, it is important to note its relation to EDEN quantization.
TurboQuant is essentially a partial implementation of EDEN quantization (first work published in NeurIPS 2021, extention published on ICML 2022). The few differences that do exist make EDEN significantly better.
