New paper out now in PRB! We discuss protecting T centre qubits during entanglement attempts. journals.aps.org/prb/abstract...
Beautiful work by PhD student Nick Brunelle and SQT alumnus Joshua Kanaganyagam with collab by Geoffroy Hautier's team at Rice University and @photonicinc.bsky.social.

Just in time for the holidays! arxiv.org/abs/2512.16047
Our PhD student Nicholas Brunelle measures the hyperfine coupling between the silicon T centre electron “communication” qubit and its H nuclear “memory” qubit—unlocking an unusual protection scheme against optically induced decoherence.

In our new PRX Quantum paper, PhD student Camille Bowness & postdoc Simon Meynell study spectral wandering of single colour centres in silicon nanocavities. We show wandering is mainly laser-induced, and narrow the effective excitation linewidth using a resonance-check scheme. go.aps.org/3IjO63h

Check out our new preprint by PhD student Michael Dobinson! We demonstrate the first electrically-injected single-photon source with silicon colour centres and opto-electrically prepare a spin qubit. arxiv.org/abs/2501.10597
