Published: May 07, 2026

Hi! We are the Quantum Utility innovator circle, led by Rakesh Arul, trying to discover new and emerging uses for quantum technologies in wet, noisy, room-temperature environments. We’re looking for people keen on:

• Building the quantum tech of the future
• Interested in using quantum tech for their own field and research
• Just keen to learn more and wondering how quantum tech can be applied
• Quantum tech skeptics who feel we should be looking at something else.

NanoSPINEC - Nanoscale spin entanglement and chemistry

Published: September 17, 2025

Using nanophotonic cavities, we will achieve the first room-temperature measurements of spin states at the single-molecule level, leveraging them to track the formation and decay of quantum correlations in exciton singlet fission (SF) and to establish the first chemical Bell inequalities through optically-detected magnetic resonance (ODMR) of triplet states.
