From Theory to Practice: Quantinuum’s First InQuanto Summer School

From Theory to Practice: Quantinuum’s First InQuanto Summer School

In September, 30 researchers gathered at Newnham College, Cambridge, for Quantinuum’s inaugural InQuanto Summer School. Supported by the UK’s National Quantum Computing Centre (NQCC), the five‑day programme blended lectures, hands‑on workshops, and mini‑projects to bridge the gap between quantum‑computing theory and real‑world chemical modelling.

A Cross‑Disciplinary Curriculum

The school opened with foundational lectures on quantum computing, followed by pen‑and‑paper and computational exercises. By Day 2, participants moved into the electronic‑structure domain, learning how chemists describe electron behaviour and how to translate those problems into qubit‑ready formats. The curriculum then covered measurement of chemistry observables, construction of quantum algorithms, and the practicalities of running them on today’s hardware.

A key feature was the free, hands‑on access to InQuanto, Quantinuum’s quantum‑chemistry software platform. Designed to accelerate research in chemistry and condensed‑matter physics, InQuanto provided a well‑documented, thoroughly tested environment where students could experiment with fermion‑to‑qubit mappings, state‑preparation circuits, and resource‑estimation tools.

Mini‑Projects: From Concept to Prototype

Participants tackled a range of problems in a day‑and‑a‑half sprint. Highlights included:

• State‑preparation programmes using mid‑circuit measurement in Guppy.
• Active‑space selection and quantum‑selected configuration interaction (QSCI) for the chromium dimer.
• Atomic valence active space (AVAS) methods to identify active spaces and estimate resources for myoglobin.

One student re‑implemented an efficient state‑preparation circuit based on orbital entanglement in InQuanto, comparing its performance with the platform’s built‑in ansatz on the Helios emulator. The mini‑projects culminated in a poster‑style session that showcased both technical depth and creative problem‑solving.

Building a Shared Language

The school’s participants came from diverse backgrounds—computational chemistry, quantum algorithms, hardware engineering, and software development. By exposing each group to the fundamentals of the others, the programme fostered a common vocabulary and a deeper appreciation of the interdisciplinary nature of quantum‑chemistry research. This shared foundation is essential for identifying where to start, challenging assumptions, and knowing when to seek expertise from another discipline.

Looking Ahead

Quantinuum’s InQuanto Summer School demonstrated the power of combining theory, practice, and community. The next steps involve extending this model to additional workshops, expanding the InQuanto platform, and encouraging participants to apply these tools to their own research challenges. Interested parties can join QNET, Quantinuum’s user community, to stay connected with future training opportunities and community events.
