Quantum mechanics has a way of sounding like pure philosophy until an experiment forces it into everyday language. In 2025, ...

Physicists have long relied on the idea that electrons behave like tiny particles zipping through materials, even though quantum physics says their exact position is fundamentally uncertain. Now, ...

Electrons are usually described as particles, but in a rare quantum material, that picture completely breaks down ...

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.

In the everyday world that humans experience, objects behave in a predictable way, explained by classical physics. One of the important aspects of classical physics is that nothing travels faster than ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

Scientists teleport quantum calculations between computers, paving the way for distributed quantum computing and a future quantum internet.

There is no measurement that can directly observe the wave function of a quantum mechanical system, but the wave function is still enormously useful as its (complex) square represents the probability ...

At 15, a Belgian prodigy finishes a quantum physics PhD and turns to AI-driven medicine, raising an unexpected question about ...

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing ...
