How can we prove the world is really quantum mechanical?
26 April 2023
A 2021 paper has got physicists discussing whether our inability to use classical physics to describe reality on a quantum scale is a human failing - and what proof is necessary to show that the world really is quantum mechanical, says Chanda Prescod-Weinstein
A macroscopic amount of matter has been put in a quantum superposition
12 April 2023
Researchers have put a sapphire crystal containing quadrillions of atoms into a superposition of quantum states, bringing quantum effects into the macroscopic world
Come explore the quantum realm – it isn’t as confusing as it seems
5 April 2023
Quantum theory, and the world of subatomic particles and forces it describes, has a daunting reputation for strangeness. And yet, with the right guidance, anyone can enjoy its many wonders
Quantum effects could be key to the chemistry of life on Titan
18 March 2023
Saturn’s moon Titan is too cold for many types of chemical reactions, but quantum tunnelling could present a loophole that would allow reactions that are crucial for life
Why uncertainty is part of science - especially quantum mechanics
1 March 2023
Quantum mechanics had a disordered beginning in the 1920s, and is still developing today. Science is rarely a done deal, says Chanda Prescod-Weinstein
Why the most important topic in physics could be statistical mechanics
1 February 2023
Statistical mechanics helps relate the quantum world to objects that seem solid and not governed by the whims of observation, but there are still questions to be answered, says Chanda Prescod-Weinstein
Quantum trick sees light move forwards and back in time simultaneously
10 November 2022
Placing a particle of light in a superposition so that it is travelling both forwards and backwards in time could prove useful for quantum computation
Quantum watch is a 'completely new way of measuring time'
24 October 2022
A quantum stopwatch made of lasers and helium atoms can measure the time that has passed with complete accuracy, without counting seconds like other clocks
A new kind of time crystal has been created and lasts 10 milliseconds
9 June 2022
A time crystal has been created by firing lasers at rubidium atoms. It only lasts for 10 milliseconds, but it could reveal the precise scale at which quantum effects take hold
