I recently published the LaTeX notes I took in three amazing classes this semester: - Computational quantum physics (Prof. @gppcarleo.bsky.social) - Quantum information theory (Prof. @qzoeholmes.bsky.social) - Sublinear algorithms for big data analysis (Prof. Michael Kapralov) Link below👇
Two-panel drake meme, titled "Morris' algorithm be like".
Top panel: Drake looks away, disapprovingly, next to the legend "Counting to n in O(log n) space".
Bottom panel: Drake points approvingly at the legend "Counting to n in O(loglog n) space.

Ab-initio preprint: we study high-pressure hydrogen over a relatively large range of pressures and temperatures (in the Born-Opp. approx.). Crucially, we do it with a **single** wave function for all values of proton configurations. Effort led by my PHD David Linteau, arxiv.org/abs/2504.07062 (1/2)

​Excited to share our latest quantum chemistry preprint led by Clemens Giuliani. We employ a "simple" variational wavefunction composed of a few hundred optimized non-orthogonal Slater determinants, achieving energy accuracies comparable to state-of-the-art methods. arxiv.org/abs/2503.14502 1/5​
Energy differences with respect to CCSD(T) in the cc-pVDZ basis set. The shaded area indicates results within chemical accuracy (1 kcal/mol) from FCI/DMRG, and the hatched area from CCSD(T). The molecules are ordered w.r.t increasing number of electrons, grouping those with equal numbers together. For those marked with * we employed a particle-hole transformation.

If it wasn't clear enough already that I have nothing against the results of Dwave, and others, read this: www.scientificamerican.com/article/are-... The problem is not the results, it's the way they are presented, and how they are perceived more broadly. (1/2)

Spot the problem(s): you have a numerical technique A for quantum systems that is not variational, you apply it to system X, then compare it to a variational method B previously applied to system Y and you extrapolate it to X. Then, you claim that method B has lower energies than A!

At small scales (30 atoms), found continuous transition with signatures of hexatic order - a phase with orientational but no translational symmetry. Larger systems show sharp liquid-solid transition
