Interactive learning panels
These browser-native panels replace the old Java applet idea with modern canvas controls that work on desktop and mobile.
Move the amplitude and phase controls. The bar chart shows measurement probability, while the wave trace reminds you that phase matters before measurement even when probabilities look similar.
P(0) / P(1)
Change analyzer angles and entanglement strength. A maximally entangled singlet-like pair gives angle-dependent correlations that can violate classical Bell limits in the right settings.
Correlation: 0
Unknown state
Choose Alice's two classical measurement bits. The state itself is not copied; the bits tell Bob how to correct his half of the entangled pair.
Classical bits sent: 00
Bob applies I; output state matches the input after correction.
Teleportation consumes entanglement and requires classical communication, so it cannot send information faster than light.
Each slit contributes an amplitude. The screen brightness follows the squared magnitude of the sum, so phase difference creates bright and dark fringes.
The Bloch sphere visualizes a pure two-level quantum state. Angles set the amplitudes and relative phase before measurement.
A particle with energy below a barrier can still have nonzero transmission because its wavefunction decays through the classically forbidden region.
Momentum spread estimate: 1.04
CHSH S: 2.828
Output: equal superposition
