And then topped it off by revealing that he himself is the descendant of immigrants πŸ™‚.

So in summary, he complained of immigrants, ecological initiatives, all global institutions.
Accused all countries of exploiting the US & Europe.
Then went on to describe how they "settled continents", colonized the world and committed mass genocides left and right.

I wonder what was the main roadblock. There must have been a big obstacle that somehow vetoed all solutions to the war in Gaza, if only one could figure out what was it πŸ€”

My recommendation: read the paper, an excellent work marking IMHO another milestone for quantum chemistry, congratulations to all authors.
To add to the cited post, the most important conclusions of the work are highlighted in the picture, a breakdown will be provided in the comments.

This year I got my first publication, first conference, and 16 citations so far.
Met a lot of people and learned a lot of things.
A start to my academic journey that I never imagined. Thank you to everyone πŸ™, to many more success in the future, hopefully as a PhD!

Probing the Ground State of the Antiferromagnetic Heisenberg Model on the Kagome Lattice using Geometrically Informed Variational Quantum Eigensolver This work investigates the nature of the ground state of the antiferromagnetic Heisenberg model on fundamental kagome cells -- a triangle and a star -- using the variational quantum eigensolver (VQE) ...

September: back to business and my third pre-print came out: arxiv.org/abs/2509.18029

Started the process of looking for a PhD position (still yet to find one) it is exhausting and very frustrating but I keep my head upπŸ˜….
Put my thesis on arxiv too:https://arxiv.org/abs/2509.21555

August: went on a vacation with my friends to Oran, and went to karting (big fan of Formula 1)
It was an amazing break from academia.
Second pre-print out on arxiv: arxiv.org/abs/2508.15072

July: went to Ghana representing qBraid, met some amazing people on that trip (I won't name names in fear of forgetting someone)

It was my first official academic conference-style event, what a way to start the journey

Defended the thesis on the 22nd of June, graduated with honors, it was the greatest day of my life. The jurors were amazed with the Thesis and I never felt better.

Published my first paper (after tedious reviews)

May: finally started writing the thesis (under pressure from @thefinalcountdown.bsky.social ) and designing the experiments I wanted to run for my thesis.

June: ran the experiments June 1st, wrapped Up the thesis 5 days later, and submitted it after proof reading on the 12th

March: finally started the thesis work, understanding sampling based algorithms, went through a lot of quantum chemistry to decrypt how PyScf worksπŸ˜….

That involved a lot of very long coffee-infused nights (Ramadan)

February: organized the QNexus event in Algiers through QAlgeria and CQTech. The event was an amazing success with more than 200 students attending across 3 universities.
I delivered my first workshop on variational quantum algorithms.

Had an amazing time with the CQTech team.

Had my first pre-print come out in December 2024 (I'm counting it in this year, don't tell on me 🀫)
