Benjamin van Osch successfully defended his Master’s thesis on August 7th, entitled “Toward Automated Tuning and Charge-State Characterization of Accumulation-Mode Silicon Quantum-Dot Devices”. Benjamin has made many contributions to our lab over the past two years as an MSc student, and also prior to that as an undergraduate research assistant. Benjamin will be joining the Salfi group at UBC, with whom we collaborate, to continue his journey doing research on semiconductor quantum devices. We wish Benjamin the best of luck in his PhD and look forward to continuing to work with him through the pan-Canadian Consortium on hole spin qubits. 

Prof. Baugh and his team have been awarded supplemental funding to expand their project on Next-generation photonic source to enable quantum remote sensing and communications. The project develops tiny semiconductor devices that are controlled electrically as on-demand single photon sources. The team’s work focuses on building and testing these on-demand photon sources for future use in secure communications, quantum sensing, and precision measurement. The supplemental funding extends the project toward light at telecom wavelengths—the same range used in fibre-optic networks. Baugh and his team will focus on making these semiconductor devices more practical by controlling how many photons are emitted and exploring operation at higher temperatures. This work also strengthens collaborations with the National Research Council (NRC) and Defense Research and Development Canada (DRDC) on real-world testing and training.

New paper out! It is on designing controls for spin qubits that are robust to 1/f charge noise. Congrats to PhD student Bohdan Khromets for getting these results published in PRA as a Letter, which was also chosen as an Editor's Suggestion. Here is a link to the paper. 

Bohdan also attended the Silicon Quantum Electronics workshop in Davos, Switzerland in September, where he presented a poster on the same work.
