Hi, I'm

Jarn de Jong.

Researcher & Scientist

I work in quantum communication, cryptography & information science

CV (pdf)

About

I am a last-year PhD candidate in the QCC group of Anna Pappa at TU Berlin. QCC stands for Quantum Communication and Cryptography.

Research

In my research I have focused on two different topics, anonymous quantum communication and entanglement in quantum networks. Here is an overview of my publications, sorted by date of appearance and topic:

Anonymous quantum communication

Anonymous Conference Key Agreement (link)
Anonymous and secret communications in quantum networks (link)
Secure Anonymous Conferencing in Quantum Networks (link)
Experimental anonymous conference key agreement using linear cluster states (link)
Anonymous conference key agreement in linear quantum networks (link)

Entanglement in quantum networks

Extracting GHZ states from linear cluster states (link)
Distinguishing graph states by the properties of their marginals (link)

Coding

Both within the scope of my research and in personal projects I build software. Most of these projects are hosted on my private Gitea server, but some of these are mirrored to my public Github page.

Some of these projects include:

The Graphstabilizer python package. A set of tools that helps you simulate, analyze and draw graphstates. I’m currently preparing it for publication in the Python Package index so everyone can install through pip.
Some supplementary material for this publication

I also like self-hosting some projects. Some of these projects are:

This website (public files available here)
My private git server through Gitea
A music server
A private cloud environment through NextCloud
A private password manager

Presenting and teaching

A non-exhaustive list of my academic talks and presentations can be found here.

I enjoy teaching, explaining and lecturing. Starting from highschool I have always tutored, taught and lectured.

Although I’m less active in recent years, I was a top 10 user at the quantum computing stack exchange.

I am a ‘Tweedegraads bevoegd’ qualified physics teacher. This means I am allowed to teach physics to the first 3 years of any Dutch highschool (MAVO, HAVO, VWO). The qualification is also acknowledged in other countries.

Experiences

Scientific Employee - TU Berlin

May 2020 - present

Currently I am employed by TU Berlin as a researcher (Wissenschaftliche Mitarbeiter). Although it is within the context of my PhD, in principle it is separate from that.

Apart from my research, my tasks include:

Designing and giving lectures
Supervising BSc. & MSc. students
Scientific talks

Use case team member - QIA

Oct 2022 - present

The Quantum Internet Alliance (QIA), an EU-flagship project that aims to create the world’s first quantum internet, built in Europe.

I am currently part of QIA’s Use Case team, where we research and develop use cases for the (future) quantum internet.

My tasks include:

Developing and simulating use cases
Writing reports for the European Commission
Categorisation of quantum networking protocols
(Brief) interim team lead

Visiting Researcher - LIP6

May 2023

I was a visiting researcher in the quantum information team of Laboratoire d’Informatique de Paris 6 at CNRS and Sorbonne Université in Paris. I presented my previouis work, and I started collaborations with various researchers.

Researcher - QuTech

Okt 2019 - March 2020

I was a soft- and hardware developer at QuTech, where in a team of 3 we developed a MVP for an MDI-QKD system.

The work span-off into QBird in 2021.

Intern - TNO

Jul - Oct 2019

I was an intern at the Quantum Technology department of the Netherlands Organisation of Applied Sciences research (TNO).

My tasks included:

Designing and developing experiments for upcoming quantum device
Developing calibration software for upcoming quantum device
Software development and simulation

Teaching intern - Gymnasium Sorghvliet

Sept 2014 - Feb 2015

In the scope of my bachelors minor I was a physics teacher intern at the Christelijk Gymnasium Sorghvliet in The Hague, NL.

My tasks included:

Designing and giving classes
Designing and taking exams
Hosting ‘ouderavonden’ (teacher <-> parent talks)

This internship culminated in a ‘Tweedegraads bevoegdheid’ high school teaching qualification in physics.

Teaching & Tutoring - TU Delft

2011 - 2018

During both highschool and university, I have tutored, been a teaching assistant and have taught a yearly retake course.

My roles included:

Tutor of high school students while in highschool, including my own classmates.
Teaching assistant for various BSc. courses
Teaching a yearly retake course of multiple math courses. This included lecturing, managing the course, creating handouts, supervising exams and grading.
Designing various MOOCs on quantum computing in a team of 5 students and two professionals.
