Practical and Asymptotically Optimal Quantization of High-Dimensional Vectors in Euclidean Space for Approximate Nearest Neighbor Search

Summary: Extends RaBitQ to B bits per dimension for flexible, high-rate quantization in high-dimensional Euclidean ANN. Preserves RaBitQ's asymptotically optimal space-error guarantees, with efficient implementations; experiments show superior accuracy and speed at the same memory.
