Dear all, last Monday (May 1) there was no lecture due to a public holiday in Norway.
This week I wanted to ask you if we can switch our lecture to Friday instead of Monday, and if possible Friday from 10am to 12pm. Let me know if this fits. I am busy grading (final exam project) today and tomorrow the course I teach here in Michigan (classical mechanics with some 60 students) and need both days for grading.
If possible thus, it would be better if we can switch to the this coming Friday. The lecture will then be in person since I am in Norway then. We can meet at the CCSE, room F?467. We can also begin earlier if you want, say 9am and use time to discuss the project as well. If needed, we will also have a last lecture on Monday 15 or sometime later the week thereafter.
I hope this works for you all and best wishes for the week.
In summary, the lecture tomorrow, Monday 12pm-2pm, is moved to Friday starting either 9am or 10am.
Best wishes,
Morten

Dear all, we hope you have had a wonderful weekend. For FYS5419/9519, the plans this week is to wrap up our discussions of the project and if there is an interest we can discuss quantum fourier transforms as our last topic. The week of May 1-5 there is no lecture since May is a public holiday. We will have our last lecture on May 8, with a summary of what we have done with discussions of the project.
Best wishes to you all,
Morten

Dear all, we hope you have had a great break.

The plans for this week are to discuss and finalize how to implement the VQE method for the  eigenvalue problems discussed in the project.  We will also discuss how to use gradient descent methods with and without analytical gradients. 

The material on gradient descent methods is taken from FYS-STK4155, see 

https://github.com/CompPhysics/MachineLearning/blob/master/doc/pub/week39/ipynb/week39.ipynb and the expressions for the analytical gradients are taken from the article of Schuld et al, see 

https://journals.aps.org/pra/abstract/10.1103/PhysRevA.99.032331

We will go through these derivations during the lecture on Monday April 17. The lecture notes (they are updated continuously) are at

Dear all, here follows an update from Monday's lecture (Monday March 20).
I have updated  the material from the weeks of
1) March 13-17 on the Lipkin model and the VQE, see for example the notebook at 
https://github.com/CompPhysics/QuantumComputingMachineLearning/blob/gh-pages/doc/pub/week8/ipynb/week8.ipynb
2) March 20-24 again on the Lipkin model, VQE and the project. see the notebook at https://github.com/CompPhysics/QuantumComputingMachineLearning/blob/gh-pages/doc/pub/week9/ipynb/week9.ipynb

The latter contains the derivation of the Lipkin model in terms of the Pauli matrices and may be useful for the solution and understanding of the project. 

Next week we will study how to write our own code and/or using Qiskit in order to find the eigenvalues using the VQE method. We will dedicate most of the time to this and link the discussions with the solution of the project. You find the project description at https://gi...

Dear all,
I promised to have the project description ready by Wednesday (March 15) this week. I was however delayed and I would need at least one more day to finalize it. I will post it online either Saturday or Sunday, together with the lecture notes for next week as well.
However, since we will simulate the Lipkin model discussed last Monday 9March 13), see https://github.com/CompPhysics/QuantumComputingMachineLearning/blob/gh-pages/doc/pub/week8/ipynb/week8.ipynb and the video at https://www.youtube.com/watch?v=ffIwxiUJGT4,
I would like to propose that when you all meet today for project work at 12pm, that you try first to see that you agree with  equations 27 and 31. Furthermore, show that you can rewrite the Hamiltonian for the J=1 case as equation 40. This is the equation we will start to simulate. In the above jupyter -notebook you will see how Equation 40 is simulated using qiskit.
The project will start with such simpler Hamiltonians and use ...

Dear all, we started this week with a discussion of various quantum gates (one qubit and two-qubit). This will lead us to a discussion of how to set up these quantum gates in order to define quantum circuits for measurements and computations.
Next week, since I will be in Norway, we are planning upon an extended session on Monday, with hands-on introduction to IBM's software Qiskit, see https://qiskit.org/
We will continue also our discussion of gates. The hope is to run lectures and introduction to Qiskit in a workshop-like style and we would like to propose that we start at 1015am and try to stay on till 2pm if needed.
The teaching material from last week is at
-https://github.com/CompPhysics/QuantumComputingMachineLearning/tree/gh-pages/doc/pub/week6. This material will be updated asap. The

This week we start discussing quantum circuits and quantum gates and prepare the ground for our first quantum computations (next week, March 6-10).
