TurboQuant is [a quantization method developed by Google](https://research.google/blog/turboquant-redefining-ai-efficiency-with-extreme-compression/). It operates by applying a fast random rotation to vectors before compression, which evenly redistributes data across coordinates. This allows applying a single pre-computed, globally optimized quantization mapping across the dataset, enabling TurboQuant to work effectively with any vector distribution and overcoming a key limitation found in binary quantization.

TurboQuant uses asymmetric quantization automatically: only stored vectors are compressed, while queries are scored in full precision. This improves accuracy and requires no additional configuration.

For instance, Qdrant uses 32-bit floating numbers to represent the original vector components. Scalar quantization allows you to reduce the number of bits used to 8.
|

In other words, Qdrant performs `float32 -> uint8` conversion for each vector component.

[Binary quantization](/articles/binary-quantization/) is an extreme case of scalar quantization.
|
||||
This feature lets you represent each vector component as a single bit, effectively reducing the memory footprint by a factor of 32. This is the fastest quantization method, since it lets you perform a vector comparison with a few CPU instructions. Binary quantization can achieve up to a 40x speedup compared to the original vectors.

However, binary quantization is only efficient for high-dimensional vectors and require a centered distribution of vector components.

chunks and quantizing each segment individually.

Each chunk is approximated by a centroid index that represents the original vector component.

The positions of the centroids are determined through the utilization of a clustering algorithm such as k-means.
