Entanglement and Nonlocality Entanglement: The separated but “entangled” parts of the same quantum system can only be described by referencing the state of other part.

The possible outcomes of measurement M2 depend of the results of measurement M1, and vice versa. This is usually a consequence of conservation laws.

Nonlocality: This “connectedness” between the separated system parts is called quantum nonlocality. It should act even of the system parts are separated by light years. Einstein called this “spooky actions at a distance.”

Interference Detection

Mach-Zehnder Interferometer

Cramer Half-Slit

Interferometer

MZ Advantages: Interference with full incident beam.

MZ Disadvantages: extremely difficult to align (4 reflecting surfaces aligned to wavelength-scale precision); path is momentum-independent.

Retrocausal Signaling

We have 10 km of high quality optical fiber coiled in the corner of the laboratory. We split the V-polarized entangled photon beam with a D-mirror, and pass each of the two paths of entangled photons through 10 km of fiber.

The H-polarized entangled photons have no optical delay, and the signal is received as soon as these photons are detected at D1,2, which is about 50 ms before the signal is transmitted, when the twin entangled photons arrive at D3,4.
