Congratulations to my PhD student Moein Kazemi for winning the top poster prize at Quantum Days 2026! Read our paper on this work here: https://t.co/1dZVqhDomK
New PRL! We find a giant isotope effect in silicon T centres: swapping H → D massively boosts lifetime and emission efficiency. Great modelling from Mark Turiansky (NRL). Lead authors Moein Kazemi & Mehdi Keshavarz pictured in our lab at SFU. https://t.co/vViXo95Fdr

New paper out now in PRB! We discuss protecting T centre qubits during entanglement attempts. https://t.co/yPiHdd5Kd0
Beautiful work by PhD student Nick Brunelle and SQT alumnus Joshua Kanaganyagam with collab by Geoffroy Hautier's team at Rice University and @TeamPhotonic.
https://t.co/UNXQHoYoZK Surprising result! Our team found 5x longer deuterated T centre lifetimes. Heavier mass lowers C–H stretch energy, suppressing phononic decay. Near-perfect emission efficiency, unheard of for silicon colour centres, means better quantum light sources and repeaters!
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. https://t.co/7edq3ZvaXG
Spectral diffusion of T centers in silicon photonic crystal cavities is studied, modeled, and ultimately reduced, with future applications in quantum networking and photonic quantum computing. @DanHigginbottom@camillebowness@quantumstef

Excited to share our new paper by PhD student Michael Dobinson in Nature Photonics: https://t.co/lEGlaVOiwO
We show single-photon emission + spin initialization by electrical injection in cavity-enhanced, single-defect silicon diodes. Much more to come on these devices! #SFU #QuantumTech
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. https://t.co/tbZncJb4Mb
Big thanks to the SQT team, @quantumstef, and our industry partners @TeamPhotonic
Hot off the press from the Silicon Quantum Technology Lab at @SFU Physics. In this collaboration with Christoph Simon's team at the University of Calgary we explore the potential of quantum networking technologies built from ensembles of silicon T centres.
