DENVER — An urgent call comes in from the White House. But the recipient is skeptical: They need a way to verify that the message comes from the purported location. Quantum physics has a solution.

Here’s what you’ll learn when you read this story… A mind-bending theory called quantum immortality suggests that your consciousness shifts to parallel universes after you die. The theory is an ...

Google's quantum division is primarily known for its research into superconducting qubits. It is now expanding its focus to another architecture.

MIT physicists have built a powerful new microscope that uses terahertz light to uncover hidden quantum motions inside superconductors. By compressing this normally unwieldy light into a tiny region, ...

One afternoon in October 1979, Gilles Brassard was swimming outside a beachfront hotel in San Juan, Puerto Rico, when a stranger swam up to him and changed the course of his career. Without so much as ...

Inside most photonic chips, light races through tiny optical wires. It carries information far faster than electricity can in many conventional systems. But once that light is trapped on the chip, ...

Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science. Reading time 6 minutes The use of the word “quantum” has become ...

Researchers at the University of Tuebingen, working with an international team, have developed an artificial intelligence that designs entirely new, sometimes unusual, experiments in quantum physics ...

A Paris-based venture firm that has quietly shaped the quantum technology scenery is now making a much louder statement about Europe’s role in the future of computing, materials science, and sensing.

But after reading Decoherence and Quantum Darwinism, a book published in March 2025 by the physicist Wojciech Zurek, I’m excited by the possibility of an answer that does away with all those fanciful ...

Quantum physics paints a strange picture of the world, one filled with spooky connections, unsettling uncertainties and—perhaps oddest of all—particles that spontaneously spring into being from the ...

Quantum computing uses quantum mechanics—the physics governing particles at atomic and subatomic scales—to process information in totally different ways from today’s digital computers. Instead of ...
