Cause and effect may not actually be muddled in the quantum realm
13 September 2024
The direction of cause and effect was brought into question for quantum objects more than a decade ago, but new calculations may offer a way to restore it

How Schrödinger's cat could make quantum computers work better
6 May 2024
A quantum bit inspired by Schrödinger’s cat can resist making errors for an unprecedentedly long time, which makes it a candidate for building less error-prone quantum computers
IBM has just made error correction easier for quantum computers
18 August 2023
The difficulty of quantum error correction has been a major stumbling block for quantum computers, but IBM researchers have developed a way to make it far more efficient
Quantum computers that use 'cat qubits' may make fewer errors
5 March 2023
Quantum bits inspired by Schrödinger’s cat could allow quantum computers to make fewer mistakes and more efficiently crack algorithms used for encryption
ChatGPT can be made to write scam emails and it slashes their cost
3 March 2023
The impressive capabilities of ChatGPT can be turned to cybercrimes like phishing despite safety precautions taken by OpenAI to prevent misuse, warn researchers
A lazy fix 20 years ago means the Y2K bug is taking down computers now
7 January 2020
The millennium bug is back with a vengeance, after programmers in the 1990s simply pushed the problem back by 20 years
Time travel without paradoxes is possible with many parallel timelines
13 December 2019
Time travel brings up paradoxes that break the laws of physics, but multiple similar timelines running parallel to one another could get around this
Quantum teleportation used to send 3D information for the first time
21 August 2019
Quantum teleportation has only ever been performed with qubits, which have two dimensions. Now it’s been done with a 3D qutrit for the first time
A classic quantum theorem may prove there are many parallel universes
19 August 2019
If we accept that information can’t travel faster than the speed of light, a quantum theorem seems to require many worlds that split when you make a measurement
Quantum experiment suggests there really are ‘alternative facts’
22 February 2019
A complex probe of the foundations of quantum mechanics suggests that the nature of reality depends on who is looking – there are no objective facts we can agree on
