"Quantum Computing with ITensor and PastaQ" – JuliaCon 2022 talk by Matt Fishman showing the most up to date features of both libraries youtu.be/Mm5EaBnDSbs

Heatmap plot of <Sz> for 30 METTS at temperature T=0.05 for a system of N=100 in size:

For ITensor users new to Julia, this video is a great introduction to Julia structs: youtube.com/watch?v=pHQe3PiY…

Beautiful agreement between experiment (THz spectroscopy) and theory (dynamics computed with MPS) revealing that the quasi-1D material CoNb2O6 is described by "twisted Kitaev" interactions versus plain Ising interactions. From Morris et al. Nat. Phys. 17 nature.com/articles/s41567-0…

"What's new in ITensors.jl" by Matt Fishman happening now! youtube.com/watch?v=EIiq3TfC… live.juliacon.org

Density matrix renormalization group (DMRG) optimization of the 1D Heisenberg chain, showing the magnetization <Sz> on each site throughout and the total energy in the upper right corner. Planning to post a code example to the docs about making movies like this:

"Holographic dynamics simulations with a trapped ion quantum computer" by Eli Chertkov, Justin Bohnet, et al. using ITensor (in Julia) to benchmark and a trapped-ion quantum computer to implement quantum dynamics with circuits based on MPS: arxiv.org/abs/2105.09324

The new ITensorsVisualization.jl package lets you create an interactive visualization of a complicated tensor contraction with one line of ITensor code. Line widths correspond to index dimensions and quantum numbers are displayed. More features to come. github.com/ITensor/ITensorsV…
