Adrian Copetudo Espinosa

PhD Student

Adrian graduated in Physics from the University of Barcelona, minored in theoretical Physics. He did his Master’s at ETH Zurich, where he joined Andreas Wallraff’s lab for a quantum optics project about emitting large photon number entangled states and also for his Master’s thesis, working in the loophole-free Bell test with two quantum computers joined by a 30-meter superconducting link.

During his PhD, Adrian aims to acquire the knowledge to design and fabricate his own devices and conduct experiments that contribute meaningfully to a future fault-tolerant quantum computer.

Outside work, Adrian is a keen reader, he enjoys swimming and gaming and he loves traveling to discover other countries.

Candace Ni Ni Huang

PhD Student

Candace Ni Ni holds an MSc in Engineering Science from NCKU, Taiwan, where she researched teleportation, benchmarking protocol, and optical experiments. After her MSc, she became a RA in the Superconducting Quantum Circuit Laboratory at NTHU, Taiwan, where she worked on fluxonium and 3D transmon. Now, she is confident that, after cutting-edge research experiences in the Qcrew, she will become a mature researcher in quantum information science and facilitate the development and realization of scalable quantum technologies in the future.

In Candace’s free time, she enjoys traveling, playing piano, finding good restaurants to eat, baking desserts especially chocolate ones, and making friends with people from different cultures!

Clara Fontaine

PhD Student

Clara graduated from Cornell University where she studied Electrical and Computer Engineering (B.S) as well as Engineering Management (M.Eng). Her past research and project experiences are diverse, including designing a quantum optical Ising computer, analyzing privacy-enhancing technologies for healthcare data, and innovating on floating offshore wind turbines. Through her Ph.D experience, she hopes to hone her ability to find innovative solutions to complex challenges, and make a transformative impact at the intersection between technology, science, and social justice.

Clara’s favorite type of adventure is immersing herself in cultures from all over the world. She loves to competitively dance bhangra, bake and cook recipes from unexplored cuisines, read historical and political fiction from diverse authors, and travel to meaningfully connect with others from different social identities!

Fernando Valadares

PhD Student

Fernando graduated in electronic engineering and solid-state physics at the Aeronautics Institute of Technology, Brazil.

Fernando was banned from Reddit for the first time in 2019 and turned it into a hobby. Likes to interact with chickens around Outram Park and is constantly thinking about how cool it would be if “revolver” was a palindrome. Generally curious about inductors. Is currently seeking a group with whom to practice competitive racquetball.

Jonathan Schwinger

PhD Student

After experimenting with quantum dots during his bachelor’s and implementing quantum algorithms to analyze run time implications, if said algorithms are run on a NISQ device, in his master’s, Jonathan now eager to climb the ladder of abstraction down to its last rung and face quantum mechanics hands-on by designing and implementing superconducting qubits.

As one of the most exciting and promising fields of our time, quantum computation combines the exploration of the quantum realm with the possibility to harvest its powers. Or in layman terms, what and so what!

Kyle Chu

PhD student

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

PhD Student

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

Research Assistant/PhD student

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.

May Chee Loke

Research Assistant

May Chee received her B. Eng in Engineering Science from NUS in 2023, with a specialisation in Nanoscience and Nanotechnology. While ardently intrigued by the peculiarities of quantum phenomena, she also aspires to realise them into actual devices that can benefit the humankind. She hopes that her background in nanotechnology will help her to become a valuable team member in the fabrication of quantum devices.

In her free time, she enjoys listening to classical music, going to art galleries, and reading. Art, be it paintings, literature, or music, inspires her to appreciate the greatness of the humankind’s ability to create. She also loves to travel, and some of her itineraries include visiting deceased artists’ home and their graves.

Celine Trieu

PhD student

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.
