Wojciech Roga, Ph. D.

I am a theoretical physicist working on quantum technologies. My interests include quantum information theory, open quantum systems, quantum enhanced imaging and quantum computing. I am interested in the interdisciplinary approach linking quantum technologies with computer science, quantum chemistry, data analysis, compressive sensing, etc.

I received my Ph.D. in theoretical physics in 2011 at the Jagiellonian University in Cracow, Poland. Next I worked as a postdoc researcher at the University of Salerno in Italy, and Strathclyde University in Glasgow, UK. In 2017 I got a Japan Society for the Promotion of Science fellowship for short term research in Japan. In 2018 I joined the Quantum ICT Advanced Development Centre at the National Institute of Information and Communications Technology in Tokyo.

Currently I am a researcher in the Quantum Information and Communication Theory Group in the department of Electronics and Electrical Engineering at Keio University and a member of the Keio Quantum Computing Center.

Kazufumi Tanji 

Grade: D3
Finished High School: Shinjuku High School

About Research: I transferred to the Takeoka laboratory this year (2022). I’ve joined the distributed quantum computing project in this laboratory. Because I have been curious about the hardware of quantum computers, I’m delighted to research the center of my interest now. Although a quantum computer is still developing currently, and there are uncountable difficulties, I enjoy challenging the obstacle with mathematics and physics.

Others: I like to listen to the radio while I cook. I belonged to the astronomy club in my bachelor’s, so I’m also fond of looking at stars.

CHEVALIER Baptiste

Grade: D3
Old University : Sorbonne (France)
Research field and interest : I graduated with major in Computer Science and got a Master’s in Quantum Information. Thanks to my master study, I believe to have a strong knowledge on the different field of quantum information. The main topics of the research I perform at Takeoka’s Lab are “Variational Quantum Algorithms (VQA)” and “Quantum Machine Learning (QML)”. In particular, I am currently focusing on applications of quantum shallow circuits. In general, I am pretty excited about NISQ devices applications, since they can most of the time turn out into concrete applications for quantum computers.
