This article explores how our understanding of the universe has evolved—from the scale of everyday experience down to the Planck length ...

But Luis Jauregui’s work, which might power quantum computers needed for long-range space exploration, also shows how basic research is a smart investment.

While William Rowan Hamilton isn’t a household name like, say, Einstein or Hawking, he might have been. It turns out the Irish mathematician almost stumbled on quantum theory in the or ...

Astrophysicist Paul Sutter explains Quantum Mechanics - the body of scientific laws that describe the wacky behavior of photons, electrons and the other particles that make up the universe.

The measurement problem in quantum mechanics looks at how an experimental outcome changes, simply by observing it.

What is the meaning of life? Even the best of us couldn't hope to answer that question in a Universe Today article. But there are those who would try to "constrain" it, at least in terms of physics. A ...

In an article published in Communications Physics, researchers from the Université libre de Bruxelles and the Institute for Quantum Optics and Quantum Information in Vienna present a new framework for ...

Two experiments with different quantum computers showcase their growing ability to simulate materials and quantum matter that have so far proven elusive in the lab ...

A time crystal is a form of matter that shows continuous, repeating patterns over time, much like how atoms in a normal crystal repeat in space. Examples once existed in only complex, quantum matter, ...
