QDNL Visitor Programme Spotlight: Exploring Time-Correlated Noise in Quantum Computing at QuTech
As part of the Quantum Delta NL Visitor Programme, Adrien Py, a Master’s student from Centrale Lyon, spent six months at QuTech, Delft University of Technology. His visit focused on advancing our understanding of time-correlated noise effects in quantum computing, specifically through Gate Set Tomography (GST) — a technique for characterizing quantum gates with high precision.
“It was an honor to work in the Rimbach-Russ group at QuTech, I was impressed by the diversity and depth of research happening in such a close-knit team.”
During his stay, Adrien developed analytical and numerical models to explore how quasi-static, time-correlated noise influences the accuracy of GST. His findings revealed how such noise scales with circuit length, affects the spread of reconstructed parameters, and causes certain noise components to be misattributed to incorrect gates — offering valuable insights into the robustness of current quantum characterization protocols.
This research not only shaped his Master’s thesis but also laid the groundwork for a collaborative paper with his QuTech supervisor, Dr. Maximilian Rimbach-Russ. Adrien will continue refining these results from France, with plans to pursue a PhD in quantum computing.
“The experience has been pivotal. Working at QuTech deepened my understanding of quantum noise and connected me to an inspiring international network of researchers.”
The Quantum Delta NL Visitor Programme supports such exchanges to foster collaboration and accelerate innovation across Europe’s growing quantum ecosystem. Adrien’s work at QuTech exemplifies the value of connecting emerging scientists with leading Dutch research groups in quantum technology.
