We're hiring two full-time technical research scientists to support establishing Vancouver's metropolitan quantum network. If you have experience in quantum key or entanglement distribution then we want you to come work with us in beautiful Vancouver! tre.tbe.taleo.net/tre01/ats/…

Welcome to the SQT team Kyle MacRobbie! Kyle comes to us from the University of Waterloo and for his MSc research he'll be working on T centre devices including strain tuning and diodes.

PhD student Nicholas Brunelle has just returned to us from ICPS 2026 in Tokyo, where he presented work from an upcoming manuscript reporting optical coherent population trapping in a silicon colour centre. Keep an eye out for the paper! pub.confit.atlas.jp/en/event…

Farewell to our postdoc Simon Meynell, who is off to Patrice Bertet's group at CEA Paris-Saclay! It has been a delight working with him on T centre spectral diffusion and optical cluster states. Read Simon's paper on T centre spectral diffusion here: doi.org/10.1103/9dxr-gfqf

So proud of our PhD graduate Camille Bowness! She triumphantly defended her thesis "The Optical Dynamics of Cavity-Integrated T centres" and you can read it here: summit.sfu.ca/item/40468. Camille started her MSc with SQT even before I joined the lab! What will we do without her?

New preprint! We tune the emission frequency of T centres integrated with optical cavities diodes. We're able to vary the emitter lifetime by spectral tuning, and to delay emission by controlled ionization. More tools in the kit for T devices. arxiv.org/pdf/2604.25170

Phys.org covered some recent work of ours on the vibrational modes of silicon T centre isotopic variants: phys.org/news/2026-02-heavie…

Congratulations to my PhD student Moein Kazemi for winning the top poster prize at Quantum Days 2026! Read our paper on this work here: doi.org/10.1103/4mpw-664z

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. journals.aps.org/prl/abstrac… @SFUPhysics

New paper out now in PRB! We discuss protecting T centre qubits during entanglement attempts. doi.org/10.1103/m23d-b4vg Beautiful work by PhD student Nick Brunelle and SQT alumnus Joshua Kanaganyagam with collab by Geoffroy Hautier's team at Rice University and @TeamPhotonic.

arxiv.org/abs/2510.23862 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. rdcu.be/eJIXs

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

Excited to share our new paper by PhD student Michael Dobinson in Nature Photonics: rdcu.be/eFFQf 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. arxiv.org/abs/2501.10597 Big thanks to the SQT team, @quantumstef, and our industry partners @TeamPhotonic
