Quantum particles can feel the influence of gravitational fields they never touch
A quantum phenomenon predicted in 1959, the Aharonov-Bohm effect, also applies to gravity.

A century of quantum mechanics questions the fundamental nature of reality
A century after the quantum revolution, a lot of uncertainty remains.

Physicists have coaxed ultracold atoms into an elusive form of quantum matter
Quantum spin liquids could be used to help protect fragile information in quantum computers.
- Quantum Physics
Scientists finally detected a quantum effect that blocks atoms from scattering light
When all available quantum states are full, atoms can’t scatter light, thanks to the Pauli exclusion principle, new experiments show.

Scientists are one step closer to error-correcting quantum computers
In a quantum computer made with trapped ions, multiple quantum bits were combined into one to detect mistakes.

One of nature’s key constants is much larger in a quantum material
The fine-structure constant is 10 times its normal value in the material, giving a peek into what physics in an alternate universe could look like.
