Can quantum eraser really change the past?

“I still can’t believe what I saw during the quantum eraser experiment.” “The photons were fired through a double-slit and initially saw the expected interference pattern on the detector screen. But when we introduced the which-path detector, the pattern disappeared as if the photons behaved like particles. It was like they were erasing their wave-like behaviour. It was a mind-bending experience that challenged everything I thought I knew about quantum mechanics.” In this article, we will discuss how this works.

So, Get ready to experience the incredible power of the quantum eraser experiment!

What is a quantum eraser experiment?

The quantum eraser experiment is a thrilling journey into the fascinating realm of quantum mechanics, where strange and paradoxical phenomena come to light. It investigates the relationship between measurement and the behavior of entangled particles and raises questions about the nature of reality and the limitations of our current understanding of the world. The experiment provides a testable demonstration of some of the most mysterious and seemingly paradoxical aspects of quantum mechanics. It has opened up new avenues for further exploration and discovery in the field of physics.

How quantum eraser works

The experiment typically involves creating two entangled particles, such as photons or electrons, and then separating them, so they are sent in different directions. When the photons were fired through a double-slit, creating an interference pattern on a detector screen by introducing a “which-path” detector, the scientists determine which slit each photon passed through, changing the state of the photons and eliminating the interference pattern.

But when the scientists introduced a second entangled photon to the first, erasing the “which-path” information and restoring the interference pattern. The result was shocking. When the measurement information from the first particle is “erased” or removed, the interference pattern disappears, and the second particle no longer exhibits quantum behavior. 

This shows that measurement can significantly impact the behavior of quantum systems and suggests that consciousness may play a role in shaping reality.

How can quantum solve the question of time travelling

For over a hundred years, we’ve relied on Albert Einstein’s theory of general relativity to understand the workings of time and space. It combines space and time into a single entity called “spacetime” and has proven highly accurate.

Despite this, physicists have been figuring out if time travel is possible within general relativity. They’ve written equations that could describe it, but theories are just theories until proven by reality.

And that’s where quantum mechanics comes in. Some interpretations of quantum mechanics, like Everett’s “many-worlds,” suggest that different histories can split and one can change the outcome of events. However, these are just speculations and have yet to be proven.

Is time travel possible?

Currently, my team and I are working on finding a theory of time travel that incorporates multiple histories and is compatible with general relativity. While finding such a theory wouldn’t guarantee that time travel is possible, it wouldn’t rule it out either.

Join us to explore the unknown and unravel the mysteries of time travel.
