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.

‘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.

Drones could help create a quantum internet
Flying drones sent entangled particles of light to two locations a kilometer apart.

The new light-based quantum computer Jiuzhang has achieved quantum supremacy
A second type of quantum computer has now performed a calculation impossible for a traditional computer.
- Quantum Physics
Galileo’s famous gravity experiment holds up, even with individual atoms
When dropped, two types of atoms accelerate at the same rate despite their differences, much like objects in Galileo’s leaning Tower of Pisa experiment.

A measurement of positronium’s energy levels confounds scientists
A gap in the energy levels of positronium seems to be substantially larger than predicted, and physicists don’t know why.

To live up to the hype, quantum computers must repair their error problems
Before quantum computers can reach their potential, scientists will need to master quantum error correction.

This weird quantum state of matter was made in orbit for the first time
Bose-Einstein condensates made on the International Space Station could reach temperatures lower than any known in the universe.

Physicists exploit a quantum rule to create a new kind of crystal
Cold atoms can form crystals as a result of the Pauli exclusion principle.
- Physics
A newfound superconducting current travels only along a material’s edge
In a first, scientists spot electricity flowing without resistance on the rim of a topological superconductor.
