Wanted: Students for Pre-PhD Research ProjectsI’m looking for students for several quantum computing research internships (unpaid). You should have:

– a BSc in mathematics (better: MSc in mathematics)

– solid background in applied mathematics

– experience writing math-ish computer code

– be ready to work with Pluto notebooks in Julia.

Not all projects are equal, but likely, you’d get a paper draft plus very basic proof-of-concept Julia notebooks, and you’re asked to improve the methods or add to the theoretical understanding.

All projects target challenges in quantum computing.

## Research

Theoretical computer science, applied mathematics, quantum computing.

My papers on arXiv:##### Projects

**NordiQuEst**2022-2025

Endeavor to establish a “nordic” quantum computing cloud platform for users to access quantum computing devices and HPC-powered quantum circuit simulators. The idea is to avoid the disadvantages that commercial cloud-QCs have. Funded by NeIC.

## Research Group

**Current PhD students**

- Evgenii Dolzhkov: Quantum algorithms
- Javier Gil Vidal: Mathematics of quantum computation
- Â½ Anti Ingel (MSc Uni Tartu)

##### Some former students

- Abdullah Makkeh, PhD 2018 âžœ postdoc in GÃ¶ttingen
- Mirjam Friesen, BSc âžœ PhD Uni Magdeburg, Germany
- Michael Bode, Diploma âžœ PhD Birmingham
- Thorsten Bonato, Diploma âžœ PhD Heidelberg

##### Information for prospective students

- You need tons of math!
- You need to be able to communicate
*effortlessly*in English. (I’m mainly thinking of the*effort*of the people you’re talking to ðŸ™‚.) - I’m
*very selective*with theory-only students: If your ambition is to prove difficult theorems then I require that you are able to do the following tasks independently (i.e., without me showing you how it’s done):

â€“ Proving difficult theorems ðŸ˜…

â€“ Writing down long proofs rigorously and readably

â€“ Reading research papers; literature search. - If in addition to
*thinking*about the math you*enjoy writing quantum computing software*, then you are particularly welcome to my group. Your task will mostly be to prototype quantum-computing methods in the Julia programming language. E.g., implement some new method that we are developing, compare it to existing methods, and contribute to the design of the method. - In order to get a
*PhD in quantum computer science*in my group, it makes sense to go through the MSc program in computer science here at Uni Tartu, and specialize in Theoretical Informatics (which includes quantum computer science). Total duration (MSc+PhD) is 6 years.
