One GPU, N QubitsHow far quantum simulation goes on one consumer graphics card. cuQuantum, the memory wall, and the escape routes past it. Measured honestly, on a desk, no cluster in sight.Plucked, Struck, BlownThree musical instruments built from physics instead of samples: a wire, a bar, and a pipe in ~60 lines of Faust each, compiled to WebAssembly small enough to hand to a browser, then reverse-engineered by gradient descent.

PLATE 032026

Plucked, Struck, Blown

Three physical-modeling instruments in ~60 lines of Faust each, compiled to 9 KB AudioWorklet WASM, performed offline into a sound gallery, and reverse-engineered by batched gradient descent on a 5090.
