Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science.

Those that solve artificially simplified problems where quantum advantage is meaningless. Those that provide no genuine quantum advantage when all costs are properly accounted for. This critique is ...

It may sound like an oxymoron, but this massive nanoparticle made up of 7,000 sodium atoms is the largest to exhibit such quantum behavior. Gear-obsessed editors choose every product we review. We may ...

NEW YORK, Jan 26 (Reuters Breakingviews) - IonQ says physics-bending processors are now a mere engineering challenge, so it’s buying a foundry to test and tweak them. It’s a way to put $17 bln of ...

Schrödinger’s cat just got a little bit fatter. Physicists have created the largest ever ‘superposition’ — a quantum state in which an object exists in a haze of possible locations at once. A team ...

Just as China and the U.S. are competing in the field of artificial intelligence, they are also racing to lead the world in quantum technologies. By harnessing the smallest quantum systems—electrons, ...

Seoul National University College of Engineering has announced that a joint research team led by Professor Hyobin Yoo from the Department of Materials Science and Engineering, in collaboration with ...

Google’s latest Doodle celebrates World Quantum Day. Quantum computers are one of Google’s big research projects, but the fundamentals can be hard to communicate. For today’s Doodle, Google uses a ...

Scientists created quantum superposition states at temperatures up to 60 times hotter than their environment, challenging the assumption that quantum effects require extreme cold. This discovery could ...

Quantum states, such as quantum superposition “cat states,” are notorious for their fragility, often disappearing in the blink of an eye. But imagine keeping such a delicate state stable not just for ...
