Mistakes happen — especially in quantum computers. The fragile quantum bits, or qubits, that make up the machines are notoriously error-prone, but now scientists have shown that they can fix…

New ‘vortex beams’ of atoms and molecules are the first of their kind
Like soft serve ice cream, beams of atoms and molecules now come with a swirl. Scientists already knew how to dish up spiraling beams of light or electrons, known as…
A proposed ‘quantum compass’ for songbirds just got more plausible
Scientists could be a step closer to understanding how some birds might exploit quantum physics to navigate. Researchers suspect that some songbirds use a “quantum compass” that senses the Earth’s…
Physicists used LIGO’s mirrors to approach a quantum limit
Quantum mechanics usually applies to very small objects: atoms, electrons and the like. But physicists have now brought the equivalent of a 10-kilogram object to the edge of the quantum…
Muon magnetism could hint at a breakdown of physics’ standard model
A mysterious magnetic property of subatomic particles called muons hints that new fundamental particles may be lurking undiscovered. In a painstakingly precise experiment, muons’ gyrations within a magnetic field seem…
‘Designer molecules’ could create tailor-made quantum devices
Quantum bits made from “designer molecules” are coming into fashion. By carefully tailoring the composition of molecules, researchers are creating chemical systems suited to a variety of quantum tasks. “The…
Drones could help create a quantum internet
The quantum internet may be coming to you via drone. Scientists have now used drones to transmit particles of light, or photons, that share the quantum linkage called entanglement. The…
The new light-based quantum computer Jiuzhang has achieved quantum supremacy
A new type of quantum computer has proven that it can reign supreme, too. A photonic quantum computer, which harnesses particles of light, or photons, performed a calculation that’s impossible…
Galileo’s famous gravity experiment holds up, even with individual atoms
According to legend, Galileo dropped weights off of the Leaning Tower of Pisa, showing that gravity causes objects of different masses to fall with the same acceleration. In recent years,…
A measurement of positronium’s energy levels confounds scientists
Positronium is positively puzzling. A new measurement of the exotic “atom” — consisting of an electron and its antiparticle, a positron — disagrees with theoretical calculations, scientists report in the…
