A quantum mirror

Hi All

 

In one of the most mind-bending experiments to date, scientists have developed a quantum mirror that reflects photons before they even arrive blurring the lines between past, present and future.

This stunning feat was achieved using ultra-fast electrical pulses and a vacuum wave-guide in a superconducting circuit, bringing quantum theory to life in a way never seen before.

The experiment is based on the dynamical Casimir effect, which suggests that empty space isn’t truly empty but filled with fluctuating quantum fields. By simulating the motion of a mirror at near-light speed using electrical pulses (rather than physically moving an object), researchers created a moving boundary condition that interacts with the vacuum itself.

The result?
Real photons were generated from the vacuum, and some of them were reflected before being emitted. This directly challenges the classical understanding of causality, revealing a reality where the effect can appear before the cause.

Why this discovery is groundbreaking:
Confirms the existence of quantum vacuum radiation
Demonstrates simulated motion faster than any material object
🔋 Opens up theoretical paths for energy harvesting from the vacuum
🌀 Redefines our understanding of cause and effect in quantum physics

This isn’t just about mirrors or light. It’s about how time itself behaves at the quantum level, and how our everyday rules break down in the face of deeper universal truths.

Fascinating, and it will make the mind boggle.

@Caute_cautim. Thank you. That is fascinating. My Daddy would have been ecstatic. My Uncle talks about Daddy’s obvious joy showing him the computer at U of I. He said felt that it was blocks long that they walked by it. Wonder how many vacuum tubes that took. Of course now our cell phones have more processing power than those dinosaurs. Daddy would be amazed.

@nkeaton Just think how many valves or tubes went into Colossus WWII Computer, which was ground breaking at the time, but no one knew about it until many years later.   It had 2,500 valves.

Used for breaking German and Japanese codes.

 

You could heat your home from the resultant energy and heat consumed.

@Caute_cautim Thank you for sharing that. That was right before my Daddy went to college. He immediately had an interest in computers. He started taking some local college classes, while studying for his actuarial exams.
