Kyle Chu

Kyle did his B.Eng in Computer Engineering at the National University of Singapore from 2016 to 2020. During this time, he worked on several projects in classical computer architecture and operating systems. He hopes to be able to make use of the lessons he’s learnt from these projects to help build new and exciting quantum devices.

Kyle has a deep fascination with computers and enjoys spending his time tinkering with old (and usually emulated) hardware or learning some obscure programming language. Outside of the digital realm, Kyle also enjoys picking locks and playing various board games.

Aleksandr Dorogov

Aleksandr graduated in Applied Mathematics and Physics from Moscow Institute of Physics and Technology, Landau Phystech School of Physics and Research. Having worked with planar superconducting qubit systems during his bachelor’s, he is now aiming to explore other promising architectures for fault-tolerant quantum computation.

As an ebullient languages learner, Aleksandr eschews insipid English structures, evincing his alacrity in accruing copious convoluted (and sporadically grandiloquent) lexicon for the sake of being a cognoscenti of the plethora of multifarious parlances, and never quails in the face of encumbrances such as a disconcerting dearth of idiom. He likes listening to modern EDM and reggaeton and knows every single Russian pop music hit of 2000s by heart. He enjoys history and human nature by reading classic writers as Dostoevsky and Tolstoy. Aleksandr casts his competitive spirit through breaking lab records in standing on balance board and practicing various sports such as volleyball and basketball.

Amon Kasper

Amon joined qcrew as a final year physics student in 2022. Having previously been exposed to theoretical entanglement schemes in UROPS projects, he couldn’t wait to experience real entanglement in the lab, where he is now working on two and three mode cat states!

In his free time you will find him mostly upside down practicing his handstands or other calisthenics moves on the NUS turf. Do hit him up for tips! Other than that he loves backpacking through other countries, experiencing new cultures and meeting new people.

Celine Trieu

Celine received both her B.Sc. and M.Sc. in physics from the University of Hamburg in Germany. Her passion for quantum was sparked during her undergraduate studies when introduced to the world of ultracold atoms. After putting her focus in her physics education on condensed matter and superconducting technologies from a theoretical perspective she is now enthusiastic to explore the experimental landscape of superconducting qubits!

Outside of research she enjoys all kinds of crafts, from needle felting to stained glass she is always excited to try something new! She finds especially (micro-) crocheting very relaxing and loves making cute amigurumi until her hands hurt.

Héctor Calero Mas

Héctor is an engineering physicist from the Polytechnic University of Catalonia, and holds a Master’s in Applied Physics from TU Delft. During his Master’s Thesis at QuTech, he designed entanglement distribution policies for quantum repeater networks. By joining Qcrew as a PhD student, he aims to misunderstand physics at a deeper level and to face new challenges in the lab.

Born in a family of philosophers (one of his first memories is of his parents singing the “Discourse on the Method” to him), Héctor often reflects about the ethical considerations of quantum technologies, the different interpretations of quantum physics, and the unreasonable effectiveness of mathematics in natural sciences. He also enjoys practicing all kinds of sports and playing card games
