22. Quantum Chemistry I: Obtaining the Qubit Hamiltonian for H2 and LiH - Part 1

Lecturer: Antonio Mezzacapo, PhD

#Qiskit

This course is an introduction to the world of quantum computing, with an exploration of some of the key quantum algorithms and their implementations using quantum circuits, as well as the quantum hardware that is designed to run these algorithms. The course was first offered during the Qiskit Global Summer School in July 2020 as a two-week intensive summer school.

Beginning around 30:00, the presenter did not explain what the table/matrix is (are these the matrix elements of the Hamiltonian?). He just drew a table. He was clear on subspaces of n electrons, but that does not require a table to explain. Again, he did not say what the table or matrix is. That was a good question from one of the listeners about what the y-axis is, but the presenter did not answer it.

@ 32:16 I don't get where the k comes in from in the relation for N choose m. Wonder if he should have written N! / m! (N - m) ! instead of N! / k! (N - k) !

At 38:19, he was clear what the dimension is of the matrix (2^N x 2^N) but again he did not say WHAT the matrix is. He didn't even give it a name.

I think the statement [a_i, a_j] = 0 should be replaced by {a_i, a_j} = 0, and similarly for the creation operators.

The eigenvalues of the a and a+ lack roots @ 40:00

i dont think I have ever seen worse handwriting, but lecture is good
