Scientists Achieve Quantum Teleportation Over Active Internet Cables

Northwestern University engineers have successfully demonstrated quantum teleportation over fiber optic cables actively carrying Internet traffic, marking a significant step toward practical quantum communication networks that could use existing infrastructure.

Published in Optica | Estimated reading time: 4 minutes

“This is incredibly exciting because nobody thought it was possible,” said Northwestern’s Prem Kumar, who led the study. “Our work shows a path towards next-generation quantum and classical networks sharing a unified fiber optic infrastructure. Basically, it opens the door to pushing quantum communications to the next level.”

Discover How to Rewire Your Brain with Neuroplasticity

https://quantumuniversity.com.
What makes our brains react the way they do?
Is there a reliable way to condition your brain for better experiences?

Learn about synaptic pruning, the process of synapse elimination that occurs in a developing brain following the “use it or lose it” principle. Researching this phenomenon in the matured human brain has led to a very exciting field of study: Neuroplasticity.

Access the power of Neuroplasticity, and change your brain to change your life!

The Physicist Who Says Time Doesn’t Exist

In today’s episode of Theories of Everything, Curt Jaimungal and Julian Barbour challenge conventional physics by exploring Barbour’s revolutionary ideas on time as an emergent property of change, the universe’s increasing order contrary to entropy, and the foundational nature of shape dynamics.

Was our universe generated inside the quantum chaos of a black hole in another universe?

Could Our Universe Have Been Born from a Black Hole?

Black holes are among the most mysterious and fascinating objects in the universe, known for their powerful gravitational pull that nothing can escape. Interestingly, if you were to compress all the matter in the universe into a single point, you would create a black hole roughly the size of the universe itself. While we do not live inside a black hole, the similarities between black holes and our universe raise intriguing questions about their connection.

Event horizons: no escape in both cases.

Quantum teleportation has begun to change the world

Quantum teleportation, once confined to the pages of science fiction, is steadily becoming a tangible scientific achievement. Advances in quantum mechanics over the last decade have transformed teleportation from a theoretical concept into an experimental reality.

These breakthroughs have revealed innovative methods for transmitting information instantaneously over vast distances, offering transformative possibilities for computing, communication, and cryptography. Scientists are now closer than ever to bridging the gap between imagination and reality in this cutting-edge field.

At its core, teleportation in the quantum world isn’t about physically transporting objects or people, as popularized by franchises like Star Trek. Instead, it involves transmitting quantum states—essentially the fundamental properties of particles like electrons or photons—without physical movement of the particles themselves.
