How to Convert Sentence to Quantum Circuit using Python
Unlock the future of language and quantum computing in this exciting hands-on tutorial!
In today’s video, we explore how a simple English sentence can travel through an incredible pipeline — from natural language, to Pregroup Grammar, to a string diagram, and finally into a real quantum circuit using DisCoPy and lambeq.
Whether you’re curious about Quantum NLP, a student of category theory, or someone who just loves exploring cutting-edge technology, this video will guide you step-by-step through:
✨ Automatically extracting grammatical structure using spaCy
✨ Assigning Pregroup types to words (n, s, nʳ, nˡ)
✨ Building a full string diagram using cups and grammatical reduction
✨ Visualizing the syntactic structure with DisCoPy
✨ Converting the diagram into a lambeq model
✨ Generating a quantum circuit with IQPAnsatz
✨ Drawing the final circuit and understanding what it represents
You’ll see how language becomes math, how math becomes diagrams, and how diagrams become quantum circuits — all in one elegant pipeline.
If you’ve ever wondered how Quantum Natural Language Processing (QNLP) really works under the hood, this is the perfect place to start.
Sit back, follow along, and enjoy the journey from text… to tensors… to qubits. 💫
