On one end of the line: ELIZA, the psychotherapist from the 60s. First chatbot to make people believe it was human. Rulebound, scripted, deterministic. Still around on the web. On the other end of the line: yr favorite LLM. How will they react? Will they know?

Earlier this year, at post conference drinks in a bar, a Googler let slip that “everyone is working flat out on a rather special QEC experiment” but shared no more! And so, I’ve been eagerly awaiting a mysterious paper until today! arxiv.org/pdf/2408.13687

Anyway, the idea that you can't understand the cool conceptual ideas or motivation behind quantum theory without Lie algebra or fiber bundles or whatever is, in my opinion, not correct. Freeman Dyson does a remarkable job explaining it, for example: gravityandlevity.wordpress.com/2010/08/30/our…

Warning: string theory and machine learning I've been promising to do a short(?) thread about a project that I am very excited about and hope produces some interesting results, so here: This sexy little thing is a Calabi-Yau manifold. This is a 2D slice of a 6D object .🧵

John Morton pitching for silicon qubit at SEEQA. Here the Bloomsbury’s chip that uses 3 million transistors to onchip multiplex control of 1024 spin qubits, needing far fewer cables coming out of fridge. The catch: no 2 qubit gates, yet!

I have 6 or 7 posts in this series approximately planned out over the next few months, and by the time it gets to around post number 5 the thing I’m developing is going to knock everybody’s socks off… I’m seriously excited for how this project is going

I’m extremely happy to share our latest work on classical simulation of expectation values for a wide family of noiseless quantum circuits. Thread below 🧵👇

I’m grateful to the ERC for their support and excited to pursue this project! Special thanks to my students, postdocs, and colleagues Cambridge University; it would have never happened without you. I’ll be hiring postdocs and PhD students. Strong candidates are welcome to email me.

"i chose to work on very difficult problems, and solved maybe a 1/3 of them, and you know, a third is actually enough."

e.g. knowing the full info of a starting state as well as some "optimal" path to a final state does not necessarily mean you get easy access to info about the final state, e.g. adiabatic protocols. You can know the algorithm, but might not have the comp. resources to execute it.

The Welsh have got their fundamental physics AND hot beverages figured out
