A new theoretical model could solve a 50-year-old puzzle on the entropy of black holes. Developed by physicists in the US, Belgium and Argentina, the model uses the concept of quantum-mechanical wormholes to count the number of quantum microstates within a black hole. The resulting counts agree with predictions made by the so-called Bekenstein-Hawking entropy formula and may lead to a deeper understanding of these extreme astrophysical objects.

Physics World: Europe plans to build 100-qubit quantum computer by 2026
Researchers at the Dutch quantum institute QuTech in Delft have announced plans to build Europe’s first 100-quantum bit (qubit) quantum computer. When complete in 2026, the device will be made publicly available, providing scientists with a tool for quantum calculations and simulations.
Physics World: MEPs call for ‘urgent action’ to implement post-quantum encryption standards
Twenty members of the European Parliament have called for urgent action to develop a new standard for data encryption that would protect against quantum computers being used for malicious purposes. In their letter, the members urge the European Commission to develop security measures and regulations to ward off the threat of quantum computers for cybercrime and data breaches.
