2026 Nobel laureate Francis Halzen first realised that arctic ice could be used to track neutrinos. Learn about IceCube with @sfuphysics.bsky.social prof Matthias Danninger and how it inspired the Pacific Ocean Neutrino Telescope which is launching soon. www.youtube.com/watch?v=LtWp... 🧪⚛️

We are hiring! The Department of Physics at Simon Fraser University is inviting applications for two full-time continuing teaching faculty appointments at the Lecturer level. Application review will begin Dec. 1, 2026. @sfuscience.bsky.social www.sfu.ca/physics/abou...

My department is searching for two full-time continuing physics teaching faculty. Come work in beautiful BC. 🧪👩🏻‍🔬⚛️🎢🍎 @sfuscience.bsky.social

Researchers demonstrated the first quantum error-correction protocol operating across two separate quantum processors, showing that networked quantum computers can detect and correct errors using shared entanglement and real-time feedback. arxiv.org/abs/2609.13065

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/ca...

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/icp...

Congratulations to @sfubiosciences.bsky.social prof Tanya Brown, @sfuphysics.bsky.social profs @quantumdan.bsky.social and Thomas Jennewein, chemistry prof Daniel Leznoff and earth sciences prof Xinyue Xu on receiving support through the John R. Evans Leaders Fund!

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.

Farewell to our delightful postdoc Simon Meynell, who is off to work with Patrice Bertet's group at CEA Paris-Saclay! It has been a pleasure 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...

In this new preprint we tune the emission frequency of single T centres integrated with optical cavities and a lateral diode. 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...

Students from our Silicon Quantum Technology Lab at Quantum Days 2026 in Victoria, BC. A big shout out to the conference organizers for bringing so many talented quantum folks together.

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...

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 @sfuphysics.bsky.social. journals.aps.org/prl/abstract...

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.

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 quantum repeaters! arxiv.org/abs/2510.23862

Delighted to see this News and Views article on our recent manuscript. Great perspective from Benjamin Pingault. www.nature.com/articles/s41...

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

This Saturday, to celebrate the International Year of Quantum, we're opening our labs to tours and I'll be speaking about our work at SFU building the quantum internet. Come join us and see a quantum physics lab in action.

Come join us @sfuphysics.bsky.social #SFU on Burnaby Mountain this Saturday May 3rd for our Quantum Canada Open Doors 2025 event. There will be talks about our quantum research, hands-on activities and lab tours. #YVR 🧪 ⚛️ 🎢 🇨🇦

Applications are open for select graduate studies programs at #SFU, including biomedical physiology, chemistry, molecular biology and @sfuphysics.bsky.social. Canadian and US students encouraged to apply by April 25. www.sfu.ca/gradstudies/...

Very excited to share a new preprint by my PhD student Camille Bowness and postdoc Simon Meynell: arxiv.org/abs/2504.09908 The spectral fluctuations of integrated T centres are primarily laser-driven, and resonance checks can significantly increase entanglement rates in T centre quantum networks.

The Silicon Quantum Technology lab has arrived for the American Physical SocietyGlobal Physics Summit 2025 (#APSSummit25)! Look out for talks by our students Austin Woolverton and Michael Dobinson and postdoc Simon Meynell to get all the latest updates on silicon colour centre quantum technologies.

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 and our industry partners Photonic Inc.
