1 Quantum Entanglement and the Flow of ime Animations Quantum Entanglement By Mark Egdall 6/15/ 09 Copyright Ira Mark Egdall, 2009 Based on Brian Greene s he Fabric of the Cosmos
2 5. Animation on Quantum Entanglement: he wave functions of two correlated photons travel in opposite directions. - We don t know where each photon is until it hits a detector. Equal probability that left photon will transmit or reflect off polarized lens Same is true for right photon. Note: Wave functions not rigorously depicted.
3 5. Animation on Quantum Entanglement: he wave functions of two correlated photons travel in opposite directions. - We don t know where each photon is until it hits a detector. Equal probability that left photon will transmit or reflect off polarized lens. Same is true for right photon. But if one of the photons transmits, the other does the opposite. (And vice-versa.) Note: Wave functions not rigorously depicted.

8 ransmission - eflection
9 ransmission - eflection
10 ransmission - eflection
11 ransmission - eflection
12 ransmission - eflection 50/50 chance of reflection or transmission - Actual choice is purely random and cannot be predicted
13 ransmission - eflection Photon happens to be detected - in reflection
14 ransmission - eflection Photon happens to be detected - in reflection
15 ransmission - eflection Photon happens to be detected - in reflection
16 ransmission - eflection Photon happens to be detected - in reflection ight photon detected - in transmission!
17 ransmission - eflection What if left photon happens to be detected in transmission?
18 ransmission - eflection What if left photon happens to be detected in transmission? Photon detected - in transmission
19 ransmission - eflection What if left photon happens to be detected in transmission? ight photon detected in reflection! Photon detected - in transmission
20 ransmission - eflection Quantum Entanglement - Example What if left photon happens to be detected in transmission? ight photon detected in reflection! Photon detected - in transmission Photon detected - in reflection
21 ransmission - eflection Quantum Entanglement - Example What if left photon happens to be detected in transmission? ight photon detected in reflection! Photon detected - in transmission Even though the choice is random Photon detected - in reflection
22 When confronted with 50/50 random chance of transmitting or reflecting off polarized lenses - Both photons will always do the opposite thing! Photon detected - in transmission Even though the choice is random Photon detected - in reflection
23 For the photon pair: Correlated Pairs -he choice of reflection or transmission through the polarized lenses is random. -We cannot predict whether a photon will transmit or reflect. - We can only predict the odds or probability of a photon transmitting or reflecting.
24 For the photon pair: Correlated Pairs -he choice of reflection or transmission through the polarized lenses is random. -We cannot predict whether a photon will transmit or reflect - We can only predict the odds or probability of a photon transmitting or reflecting. Yet whichever of these random events occurs for one photon: - the opposite thing always happens to the other photon! End of Animation
