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

Delighted to present the recent work of our Silicon Quantum Technology lab at SFU at the Quantum Days conference in Victoria, BC today.

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!

Delighted to see this News and Views article on our recent manuscript. Great perspective from Benjamin Pingault. https://t.co/HhyYJ6OIB7

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.

Proof-of-principle measurements inform quantum memory and transduction protocols for 𝑇 center ensembles. @JiaweiJiQuantum, @DanHigginbottom, @quantumStef

Tardy maybe, but I'd better share this paper of ours from last year that got a little buzz: https://t.co/3urgCDm5ai
