Two of Quantum Mechanics' Most Insightful
Experiments You Might Not Have Heard Of
Ken Arnoult
Geophysical Institute

The Aspect experiment and the "Quantum Eraser" provide experimental verification of two of quantum mechanics' most counter-intuitive predictions. Originally suggested by John Bell, the Aspect experiment disproves the existence of local hidden variables (hence, confirming what Einstein referred to as "spooky action-at-a-distance"). The Quantum Eraser demonstrates how the impact of past events on the present can be erased by eliminating the potential for information. Both experiments will be discussed with more emphasis placed on conceptual understanding than on mathematical detail.
