This app represents phase estimation algorithm with five qubits. You can understand the every single detail of phase estimation algorithm.
Positional Encoding
Read full descriptionHide full description
This is an educational App for readers interested in the sin/cos encoding of the token positions in large language models (LLM). Play with this App to acquire a deeper understanding of the positional encoder as it was described in the famous *Attention is All You Need* paper. In particular the App shows how the correlation between two positional vectors depends only on the distance between the corresponding two integer position.
