Elusive phase change finally spotted in a quantum simulator
Researchers saw a chain of atoms in a quantum simulator go from being magnetic to not magnetic at all, the first time such a change has ever been seen in one spatial dimension
AI could assemble a record-breaking quantum computer out of cold atoms
A huge number of ultracold atoms has been corralled into a grid that could form the basis of the next largest quantum computer
Laser technique measures vast distances with nanometre precision
A new technique involving lasers can measure long distances more precisely than ever, which could be useful for space telescopes
Physicists discover the secret to perfect cacio e pepe pasta
The classic Italian cacio e pepe pasta is notoriously tricky to get right, but physicists have come up with a trick to achieve a perfectly smooth cheese sauce
Ultracold indium atoms could make unexpected new types of matter
For the first time, atoms of the metal indium have been chilled to temperatures a few millionths of a degree above absolute zero, a state where strange quantum phenomena begin to appear
Are space and time illusions? The answer could lie in black holes
Whether space and time are part of the universe or they emerge from quantum entanglement is one of the biggest questions in physics. And we are getting close to the truth
Physicists discover that 'impossible' particles could actually be real
Every fundamental particle in the universe fits into one of two groups called fermions and bosons, but now it seems there could be other particles out there that break this simple classification and were once thought to be impossible
How a quantum innovation may quash the idea of the multiverse
The many-worlds interpretation of quantum mechanics invokes alternative realities to keep everything in balance. Has solving a century-old paradox now undermined their existence?
Can we use quantum computers to test a radical consciousness theory?
Hartmut Neven, who leads Google's Quantum AI lab, wants to entangle our brains with quantum processors to test the idea that consciousness involves quantum phenomena
Physicists bend atoms in ‘impossible’ experiment
Entire atoms have been put through a classic quantum experiment for the first time and the breakthrough could lead to better detectors for picking up the gravitational waves that ripple across the universe
We could discover a new element on the periodic table in 2025
Work is under way to produce the first atom of element 120 ever seen on Earth, and the results could be in surprisingly soon
Physicists in 2024 searched the quantum realm for the truth about time
Two separate theoretical studies published this year argued that time itself is bound up in the odd quantum property of entanglement, but deep mysteries remain
Quantum entanglement can be endlessly 'embezzled' from quantum fields
Some quantum fields that extend throughout all of space-time could be a rich resource of quantum entanglement that can be extracted forever
How to make the biggest splash in a pool, according to science
Analysing footage of what happens when people jump into water, and using a robot to mimic them, has revealed how do the perfect dive-bomb using a Maori technique called the Manu
The wild physics that could actually be used to build a time machine
From warp drives to quantum tricks, here are five ways that physicists have figured out how to theoretically travel back in time
