Quantum physics requires imaginary numbers to explain reality
Quantum theory based only on real numbers fails to explain the results of two new experiments.

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.

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.

New ‘vortex beams’ of atoms and molecules are the first of their kind
Twisted beams of atoms and molecules join other types of corkscrew beams made of light or electrons.

A proposed ‘quantum compass’ for songbirds just got more plausible
Quantum physics could be behind birds’ magnetic sense of direction, new measurements indicate.

Physicists used LIGO’s mirrors to approach a quantum limit
Using LIGO’s laser beams to reduce jiggling rather than detect gravitational waves, scientists have gotten closer to the realm of quantum mechanics.

Muon magnetism could hint at a breakdown of physics’ standard model
After two decades, a new measurement of the muon magnetic anomaly reinforces earlier hints that its value disagrees with standard physics.
- Quantum Physics
‘Designer molecules’ could create tailor-made quantum devices
Scientists are making molecules suited to a variety of quantum tasks by building them up, atom by atom.
