Your educational experiment involved 54 schoolchildren, aged 15-17, who were randomly selected from around 1,000 applicants, from 36 UK schools – mostly state schools. The teenagers spent two hours a week in online classes and after eight weeks were given a test using questions from an Oxford postgraduate quantum physics exam. More than 80% of the pupils passed and around half earned a distinction. Were you surprised by their success?

At one point, I was going to call off the whole thing because I thought it was going to be a complete disaster. We’d originally wanted the kids to interact with each other on social media or communicate online, but that wasn’t allowed due to the ethical guidelines for the experiment. I thought, what sort of educational experience is it, if you can’t talk to each other?

This is the Covid generation: none of them put their cameras on [for the online classes], so we were looking at a black screen. None of them asked questions using their voices, they just typed. It was a difficult teaching challenge by all standards. We also saw a self-esteem problem with the students. But the majority of kids liked that we had announced that you didn’t need a complex maths background. The maths had been a barrier to kids who had wanted to access this knowledge.

And then we got back the numbers. They did significantly better than we see from university-level students. Exams were marked blind, so we don’t know how many came in with the aim of pursuing Stem. We are processing that data now.

Now I have questions about the Oxford postgraduate quantum physics exam :)

Exactly, how can one pass a postgraduate level exam 'without complex math'?

It didn't say their exam was an entire postgraduate exam. It said they passed an exam consisting of questions from a postgraduate exam.

I'd guess that if someone tried to take the entire exam it would include things that do require "complex math" (whatever that is). But you don't have to get to the parts of QM that require such math in order to cover things that exhibit the meat of QM, such as superposition, entanglement, and uncertainty principles. I'd guess that it was those kinds of things covered for these students and that is what they were tested on.

I have doubt that anyone with a high school maths would even understand any of these (2023 MSc QM level Oxford exam) [1] . but reading the original source on the study [2] it seems like it is not this or any of what we expect.

> This article is concerned with a new language for quantum, to which we refer as quantum picturalism (QPict) [5]. It is the subject of two books written by some of the authors, respectively entitled Picturing Quantum Processes [10] and Quantum in Pictures (QiP) [9]. The first one is the text book of an Oxford University postgraduate course that has been running for well over ten years now. The second one, remarkably, has no mathematical prerequisites beyond what is already taught to 6-7 year olds in the UK, namely angles

Quantum Picturalism: Learning Quantum Theory in High School https://arxiv.org/pdf/2312.03653 seems a longer version.

That QPict Quantum picturalism (2009) paper is https://arxiv.org/pdf/0908.1787 .

Picturing quantum processes - A first course in quantum theory and diagrammatic reasoning (2017) is https://www.cs.ox.ac.uk/people/aleks.kissinger/PQP.pdf (900+ pages; only 24 MB). Slides accessible: https://www.cs.ox.ac.uk/ss2014/programme/Bob.pdf ; slides technical: https://www.cs.ox.ac.uk/people/aleks.kissinger/slides/pdf/ak... .

Quantum in Pictures (2022) does not appear to be available open access.

String diagrams of category theory potentially make working with invariants easier by embedding them in graphical transformations, so they "just maintain themselves". Eg, electric circuit laws.[2] Or here, ZX-calculus/diagrams for QM.[3]
