Conferences 2025 - SPP11 and SCOM5
Published:
Had a fun time this year at the SPP11 conference in Tokyo, giving my first invited talk on “Nanophotonics to control mid-infrared light and polariton condensation” and giving a contributed talk in SCOM5 on the new lanthanide research direction. Good feedback and great to see scientific colleagues and learn from the community - and get new ideas!

Come join our ARIA innovator circle!
Published:
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:
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.
