Things I think should be simpler and have a lower barrier to entry:
- scientific computing
- high performance computing
- domain specific methods and solutions in numerical computing & modelling
- quantum computing
- expressing ideas in code while taking advantage of any of the above

I haven't been posting YouTube videos for a while. And there is a good reason for this. I got frustrated enough doing scientific / high performance computing day to day for quantum many body research, I decided to do something about it:

Scientists shouldn't need to be software developers.

Ouch!
"These findings substantially shift the quantum advantage frontier and underscore that classical variational techniques, which are not fundamentally constrained by entanglement growth, remain competitive at larger system sizes than previously anticipated."

Challenging the Quantum Advantage Frontier with Large-Scale Classical Simulations of Annealing Dynamics
Recent demonstrations of D-Wave's annealing-based quantum simulators have established new benchmarks for quantum computational advantage [arXiv:2403.00910]. However, the precise location of the classi...

Quantum State Designs from Minimally Random Quantum Circuits
Random many-body states are both a useful tool to model certain physical systems and an important asset for quantum computation. Realising them, however, generally requires an exponential (in system s...

Scientific communication is a key task for scientists. It can come in all shapes and sizes. From attending undergraduate recruitment events, to writing clear and concise research articles and of course engaging with a wider audience. This is an ongoing task that should be prioritized.

The best indicator of how close we are to quantum utility is that researchers who should be first or second wave adopters of the technology typically can't tell you what they'd do with it. #quantum

Am I wrong in thinking if c/c++ or other compiled languages just had good build and dependency tools, more people would adopt them in science as their default tool? Or is this wishful thinking? I like python a lot. I wouldn’t put python on the compute cluster I have access to.
