Working notes on holography, quantum information, and the odd computational detour. Rougher than a paper, more permanent than a chalkboard.
From a rotating qubit and a Bell pair to the critical Ising chain: how stabilizer Rényi moments reveal spatial structure beyond entanglement. An undergraduate introduction with an interactive example.
Holography forbids purely GHZ-like entanglement among three regions that make up the whole system. A popular account of what happens to that rule when the regions leave gaps.
The Ising minimal string, explained from a cubic curve to its first quantum correction. An interactive worked example for physics students.
