Researchers in Finland have measured an energy signal smaller than one zeptojoule using a new calorimeter. The achievement opens pathways for improved quantum computing and searches for dark matter.

Academy Professor Mikko Möttönen led the team at Aalto University, working with IQM and the Technical Research Centre of Finland. They built the device from superconducting and normal-conducting metals that respond to minute temperature shifts. The sensor registered an electromagnetic pulse of 0.83 zeptojoules after careful filtering of microwave signals. This marks the first calorimetric measurement at such sensitivity, according to the researchers.

Quantum entanglement detected in hand-sized crystal

Researchers at TU Wien have found strong quantum entanglement in a centimeter-sized crystal made of cerium, palladium and silicon. The finding shows that macroscopic materials can exhibit collective quantum behavior. It was published in Nature Physics in 2026.

Physicists revive 1773 experiment to hunt dark matter

Researchers propose updating a 1773 experiment by Henry Cavendish to detect millicharged particles, a potential dark matter candidate. The design uses nested metal shells and could be 10,000 times more sensitive than past methods. The setup promises to be cheaper and faster than particle accelerators.

Physicists reverse quantum time flow to charge batteries

Researchers at Los Alamos National Laboratory have developed a method to effectively reverse time in quantum systems, enabling energy harvesting for potential use in quantum batteries. The technique counteracts the effects of measurements on qubits, making systems appear to run backwards. This could turn measurements into a thermodynamic resource.
