QUANTUM COMPUTER
A Hadamard, then a CNOT: the two qubits become one thing. Each arrow shrinks to nothing — neither has a state of its own. Fire 100 shots: every one comes out 00 or 11, never mixed.
what am I looking at
The maths is exact. This is a state-vector simulation: n qubits are 2n complex amplitudes, every gate is the matrix a physicist would write down, and every shot is drawn with the Born rule. It is not a quantum computer — it is what one computes, done the slow way on up to 32 numbers. Each sphere is one qubit's Bloch sphere: straight up is |0⟩, straight down |1⟩, the equator is superposition. When qubits entangle their arrows shrink, because an entangled qubit has no state of its own, and the violet arch between two spheres is how correlated they are. The bars are the whole state: height is probability, colour is phase. The gold chandelier is a dilution refrigerator, where real superconducting qubits are kept at about 0.01 K — that part is illustration. Drag to turn it, pinch or scroll to zoom, double-tap to reset.
