🌀 Qubit Superposition on the Bloch Sphere: 2D Simulation

Interactive 2D view of a qubit on the Bloch sphere as two linked projections: drag the state dot to prepare any superposition, evolve it under a field with dephasing and relaxation, and measure it with Born-rule statistics.

ControlsDrag the state dot in either disc; presets (|0>, |1>, |+>, |+i>, Rabi flopping, Larmor precession, dephasing, T1 relaxation); sliders for field strength, field axis angles, dephasing, relaxation and time speed; choose measurement basis, measure once with collapse or sample 100 copies; pause, step and reset.
