Quantum PhysicsQuantum physics requires imaginary numbers to explain reality
Quantum theory based only on real numbers fails to explain the results of two new experiments.
-
Quantum PhysicsPhysicists 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 PhysicsScientists 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.
-
Quantum PhysicsScientists 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.
-
Quantum PhysicsOne 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.
-
PhysicsNew ‘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.
-
AnimalsA proposed ‘quantum compass’ for songbirds just got more plausible
Quantum physics could be behind birds’ magnetic sense of direction, new measurements indicate.
-
Quantum PhysicsPhysicists 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.
-
Particle PhysicsMuon 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.
-
Quantum PhysicsDrones could help create a quantum internet
Flying drones sent entangled particles of light to two locations a kilometer apart.
