Embracing quantum spookiness: Best ideas of the century
19 January 2026
The strange principle of quantum entanglement baffled Albert Einstein. Yet finally putting quantum weirdness to the ultimate test, and embracing the results, turned out to be a revolutionary idea
Quantum computers have finally achieved unconditional supremacy
19 September 2025
For the first time, researchers have mathematically proven that a quantum computer needs less computational power to solve a particular task than an ordinary computer, in a way that can never be beaten
Could we get quantum spookiness even without entanglement?
1 August 2025
Particles of light travelling through a maze of devices seem to have passed a famous test for entanglement – without being entangled at all
We may be able to share quantum entanglement nearly infinitely
28 July 2025
A pair of quantum experimenters that share two entangled particles may be able to pass some of that entanglement to other pairs – and keep sharing it again and again
Why John Stewart Bell has been haunting quantum mechanics for decades
12 June 2025
The “Bell test” was devised in the 1960s to uncover what’s going on in the quantum world, but it continues to be relevant today, says Karmela Padavic-Callaghan
Could we build space-time computers that run on gravity?
6 June 2025
New mathematical work provides a way to identify when information has been changed by manipulating space-time – and it may form a foundation for future space-time computers
Do we have free will? Quantum experiments may soon reveal the answer
28 May 2025
Whether or not we have partial free will could soon be resolved by experiments in quantum physics, with potential consequences for everything from religion to quantum computers
Quantum eavesdropping could work even from inside a black hole
31 March 2025
An eavesdropper hiding inside a black hole could still obtain information about quantum objects on its outside, a finding that reveals how effectively black holes destroy the quantum states near their event horizons
Quantum computers have finally arrived, but will they ever be useful?
11 February 2025
Hundreds of quantum computing firms around the world are racing to commercialise these once-exotic devices, but the jury is still out on who is going to pull ahead and produce a machine that actually does something useful
