Forskare i Finland har mätt en energisignal mindre än en zeptojoule med hjälp av en ny kalorimeter. Genombrottet öppnar vägar för förbättrad kvantdatorutveckling och sökandet efter mörk materia.

Akademi-professor Mikko Möttönen ledde teamet vid Aalto-universitetet i samarbete med IQM och det tekniska forskningscentralen i Finland. De byggde enheten av supraledande och normalledande metaller som reagerar på ytterst små temperaturförändringar. Sensorn registrerade en elektromagnetisk puls på 0,83 zeptojoule efter noggrann filtrering av mikrovågssignaler. Enligt forskarna markerar detta den första kalorimetriska mätningen med en sådan känslighet.

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.
