The recovered notes of Professor Alborough

It started off as a silly simulation. I fed the quantum computer everything I knew about the process: how heat pulls flavour from the leaves, how tiny currents move through the cup, how our taste buds respond accordingly.

I included one additional control. It was a bit of a joke at first: what if I could change the cup’s gravity just a little around the rim to avoid the dreaded slurp?

The patterns the computer returned were no joke.

The machine revealed that those tiny changes in gravity at the micrometre scale could steady the swirl of the near-boiling water, holding delicate compounds in contact with the leaves for longer and making the flavour cleaner. No slurps and maximum flavour to boot. Magnificent.

I decided to build a device that could bring those simulations to life. The resulting machine was a complex configuration of pre-existing systems that could nudge the way mass and energy behaved inside a teacup-sized region. I called the device Thomson. It felt fitting. After all, J. J. Thomson not only presided over the Cavendish from 1884 to 1918 but also instilled the twice-daily tea break that still takes place here in the laboratory, almost 200 years later. And I could only imagine my colleagues’ faces when they tasted my results!

Thomson’s first brews were incredible. The liquid moved in calm, repeating cells instead of chaotic eddies. The tea tasted impossibly balanced: sweet notes without bitterness, texture as smooth as melted ice cream. But warm. Warm melted ice cream with a tannin tang that could have been taken from the recipe books of the gods. I know these notes are not making sense. But the results were intoxicating … the chai equivalent of ambrosia.

I was satisfied.

But the quantum computer was not.

It refused to stop simulating until it had reached its primary objective: to brew the perfect cup of tea. It was my fault. A quantum computer should not be capable of such independent thought. But I had taken some of the guard rails off to run the simulations faster, letting the machine extrapolate in a way not usually allowed. I saw no harm in doing this. After all, how unethical could making a cup of tea get?
