Quantum quirk explains why carbon dioxide causes global warming
13 February 2024
A phenomenon called the Fermi resonance, which affects how molecules vibrate, is responsible for a large part of carbon dioxide’s planet-warming effect

Newton’s first law appears to break down in the quantum realm
21 July 2023
Newton’s first law of motion says that particles move in straight lines unless influenced by a force but a new experiment shows that the quantum version of that assumption fails for quantum particles of light
Quantum randomness of empty space can be controlled with a laser
13 July 2023
The minuscule fluctuations of seemingly empty space can be controlled just enough to make the building blocks of a new type of computer
Record-breaking number of qubits entangled in a quantum computer
12 July 2023
A group of 51 superconducting qubits have been entangled inside a quantum computer, not just in pairs but in a complex system that entangles each qubit to every other one
Microsoft says its weird new particle could improve quantum computers
21 June 2023
Researchers at Microsoft say they have created elusive quasiparticles called Majorana zero modes – but scientists outside the company are sceptical
IBM quantum computer beat a supercomputer in a head-to-head test
14 June 2023
Researchers at IBM pitted their 127-qubit Eagle quantum computer against a conventional supercomputer in a challenge to perform a complex calculation – and the quantum computer won
Extremely cold drop of helium can be levitated forever
9 June 2023
A drop of very cold liquid helium can be made to float for an indefinitely long time using strong magnets and quantum effects
Quantum sensors could detect space debris from its gravitational pull
30 May 2023
Devices based on quantum properties of very cold and very small crystals could be mounted on satellites and sense space debris that could collide with them
Sunlight could cool an atom to its coldest possible temperature
26 May 2023
Sunlight transmitted through an optical fibre could be used to help cool a single charged atom to a temperature only a few millionths of a degree above absolute zero
Fundamental law of physics demonstrated using quantum objects
23 May 2023
The principle of least action has been a key law of physics since the 18th century, but has only now been directly observed in the quantum realm thanks to an experiment with single particles of light
