Semester page for FYS5419 - Spring 2026

Dear all, welcome back to FYS5419/9419. This week is when the fun begins with the VQE algorithm.

Note that the lecture this week is via zoom only (direct, but it will be recorded as well as always). The exercise session runs as usual. In addition to what we discussed last week, with the information here, you should be able to start writing your own VQE code.

The first part of the lecture will focus

Review from last week, one-qubit gates and one-qubit Hamiltonian rewritten in term of Pauli matrices (with some slides from last week)

Two-qubit Hamiltonians and how to encode them in terms of Pauli matrices

Then we start discussing the? variational quantum eigensolver algorithm (VQE)?

Discussion of project 1 during the lecture and the exercise session, see the jupyter-notebooks mentioned below.

Readings

For the discussion of one-qubit, two-qubit and other gates, sections 2.6-2.11 and 3....

Dear all, welcome back to FYS5419/9419. And please excuse me for this late notice.

This week we plan to (see slides at https://github.com/CompPhysics/QuantumComputingMachineLearning/blob/gh-pages/doc/pub/week4/ipynb/week4.ipynb):

Start with a reminder from last week on Entanglement, entropy and density matrices

Discuss one-qubit and two-qubit gates, background and realizations, see also PDF file?https://github.com/CompPhysics/QuantumComputingMachineLearning/blob/gh-pages/doc/pub/week4/pdf/gates.pdf.? This file has figures which are more difficult to run properly with a jupyter-notebook.

Simple Hamiltonian systems and start discussion of project 1. Project 1 is now ready and can be found at https://github.com/CompPhysics/QuantumComputingMachineLearning/tree/gh-pages/doc/Projects/2026/Project1.? This week we will discuss mainly exercises a-b.?

Introduction to qiskit (for exercise sessions). See notes at?https://github....

Dear all, welcome back to FYS5419.?

Here are the plans for our sessions on February 4. Since Morten is away for a workshop on quantum machine learning (Sweden), the lecture will be in the form of a recording only. However, we will run the exercise session 815-10 as normal.? Thus, no regular lecture, just a recording. This will be uploaded before the regular lecture on February 4. The teaching material is at https://github.com/CompPhysics/QuantumComputingMachineLearning/blob/gh-pages/doc/pub/week3/ipynb/week3.ipynb or if you prefer the PDF variant at https://github.com/CompPhysics/QuantumComputingMachineLearning/blob/gh-pages/doc/pub/week3/PDF/

There you will also find the exercises for next week as the file https://github.com/CompPhysics/QuantumComputingMachineLearning/blob/gh-pages/doc/pub/week3/pdf/exercisesweek3.pdf

If you spot typos, errors etc, please let me know.

The plan this week is to discuss

Density matrice...

Dear all, welcome back. We hope you've had a great start of the week. With this mail we'd like to give you an overview of these week's plans, with exercises and links to possible reading recommendations. This week we have also our first exercise session, although it is not listed in the official schedule. The exercise sessions start at 815am and last till 10am on Wednesdays and we are at F?434, same room as the lectures.

Carl Fredrik Nordb? Knutsen will be there as TA, I will most likely be there around 9am.?

You find the exercises at the end of the slides from last week. The exercises for next week are at the end of this week's material, which you find at?

https://github.com/CompPhysics/QuantumComputingMachineLearning/blob/gh-pages/doc/pub/week2/ipynb/week2.ipynb

We will start with a review from last week and then move to these week's topics. That is:

Summary from last week and plans for this week

Last w...

Dear all, first a great welcome to FYS5419/9419 and thx so much for having chosen the course.

All educational material is available via the GitHub repository at https://github.com/CompPhysics/QuantumComputingMachineLearning

Furthermore, for those of you who cannot be there physically, you can attend the lectures via zoom. All lectures will be recorded.

Permanent Zoom link for the whole semester is https://uio.zoom.us/my/mortenhj?

The first part of the course (project 1 and till mid march) has its focus on studies of quantum-mechanical many-particle systems using quantum computing algorithms and quantum computers. The second part is optional and depends on the interests and backgrounds of the participants. Two main

themes can be covered:

- Quantum machine learning algorithms, implementations and studies

- Realization and studies of entanglement in physical systems

The tentative plan...
