Quantum mechanics and general relativity are the two pinnacles of 20th-century physics. In their respective fields, ...

Quantum physics has a reputation for needing exotic hardware, from liquid-helium-cooled qubits to sprawling AI clusters, just ...

Quantum computers, systems that process information leveraging quantum mechanical effects, have the potential of ...

It's one thing to dream up a quantum internet that could send hacker-proof information around the world via photons superimposed in different quantum states. It's quite another to physically show it's ...

Scientists have developed a quantum experiment that allows them to study the dynamics, or behavior, of a special kind of theoretical wormhole. Scientists have, for the first time, developed a quantum ...

A subtle timing flash may expose the Unruh effect. The approach ties ordinary lab tools to deep quantum physics. Researchers ...

New theoretical research proves that machine learning on quantum computers requires far simpler data than previously believed. The finding paves a path to maximizing the usability of today’s noisy, ...

Physicists have proposed modifications to the infamous Schrödinger's cat paradox that could help explain why quantum particles can exist in more than one state simultaneously, while large objects ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...
