The Framework

Delayed-Choice Coincidence Probability

The delayed-choice quantum eraser demonstrates one of the most counterintuitive features of quantum mechanics: measuring path information destroys an interference pattern, but erasing that information after the particle hits the detector restores correlation. Retrocausal Eraser Interference scales this optical physics into macro-scale optical delay loops, turning delayed measurement post-selection into a tool for quantum state control.

01

Entangled Photon Pair Generation

Spontaneous parametric down-conversion producing signal-idler pairs directed into space-separated interferometers.

02

Delayed Which-Way Erasure

Electro-optic switching of idler paths after signal detection to restore or erase path information retrocausally.

03

Coincidence Sub-Ensemble Sorting

High-speed correlation electronics isolating sub-ensemble interference patterns from entangled pair coincidence channels.

04

Macro-Scale Optical Delay Lines

kilometer-scale fiber recirculating loops ensuring path erasure decisions occur long after signal detection.
