Quantum Teleportation Achieved Over Internet For The First Time

A quantum state of light was successfully teleported through more than 30 kilometers (around 18 miles) of fiber optic cable amid a torrent of internet traffic – a feat of engineering once considered impossible.

The impressive demonstration by researchers in the US in 2024 may not help you beam to work to beat the morning traffic, or download your favourite cat videos faster.

However, the ability to teleport quantum states through existing infrastructure represents a monumental step towards achieving a quantum-connected computing network, enhanced encryption, or powerful new methods of sensing.

Breakthrough in Quantum Magnetism Simulation Marks Turning Point for Quantum Computing

In a new study published by researchers at quantum computing company Quantinuum and collaborators from Caltech, Fermioniq, EPFL, and the Technical University of Munich, scientists have used Quantinuum’s powerful quantum computer, H2, to simulate a notoriously difficult system—quantum magnetism —in a way that pushes beyond what classical computers can reliably achieve.

“Digital quantum computers are much more flexible/universal, but we have paid for that flexibility with many technical challenges,” Dr. Michael Foss-Feig of Quantinuum and the paper’s lead author told the Debrief.

“This paper is an indication that we are finally moving these more flexible/universal machines into the realm of practical (and scientifically illuminating) quantum simulation,” Foss-Feig said.

Scientists develop method to speed up quantum measurements using space-time trade-off

In an attempt to speed up quantum measurements, a new Physical Review Letters study proposes a space-time trade-off scheme that could be highly beneficial for quantum computing applications.

Quantum computing has several challenges, including error rates, qubit stability, and scalability beyond a few qubits. However, one of the lesser-known challenges faces is the fidelity and speed of .

The researchers of the study address this challenge by using additional or ancillary qubits to significantly reduce measurement time while maintaining or improving the quality of measurements.

Physicist revisits the computational limits of life and Schrödinger’s essential question in the era of quantum computing

More than 80 years ago, Erwin Schrödinger, a theoretical physicist steeped in the philosophy of Schopenhauer and the Upanishads, delivered a series of public lectures at Trinity College, Dublin, which eventually came to be published in 1944 under the title “What is Life?”

Now, in the 2025 International Year of Quantum Science and Technology, Philip Kurian, a and founding director of the Quantum Biology Laboratory (QBL) at Howard University in Washington, D.C., has used the laws of quantum mechanics, which Schrödinger postulated, and the QBL’s discovery of cytoskeletal filaments exhibiting quantum optical features, to set a drastically revised upper bound on the computational capacity of carbon-based life in the entire history of Earth.

Published in Science Advances, Kurian’s latest work conjectures a relationship between this information-processing limit and that of all matter in the observable universe.

Scientists Crack the Hidden Code of Quantum Entanglement

Physicists have made a major leap in our understanding of quantum entanglement by fully mapping out the statistics it can produce – essentially decoding the language of the quantum world.

This breakthrough reveals how the bizarre but powerful correlations in quantum systems can be used to test, secure, and certify the behavior of quantum devices, all without knowing their inner workings. The ability to self-test even partially entangled systems now opens doors to more robust quantum communication, encryption, and computing methods. It’s a game-changer for both fundamental physics and real-world quantum tech.

Neil deGrasse Tyson Breaks in Tears “Google Quantum Chip Just Proved Einstein’s Theory WRONG”

Our machines will be smart enough and eventually we will through intelligence enhancement.

For over a century, Einstein’s theories have been the bedrock of modern physics, shaping our understanding of the universe and reality itself. But what if everything we thought we knew was just the surface of a much deeper truth? In February 2025, at Google’s high-security Quantum A-I Campus in Santa Barbara, a team of scientists gathered around their latest creation — a quantum processor named Willow. What happened next would leave even Neil deGrasse Tyson, one of the world’s most renowned astrophysicists, in tears. This is the story of how a cutting-edge quantum chip opened a door that many thought would remain forever closed, challenging our most fundamental beliefs about the nature of reality. This is a story you do not want to miss.
