Quantum Technology Advancement Scientific Innovation Astrophysics and Dark Matter

Researchers in Finland, led by Aalto University, have developed a calorimeter capable of measuring energy levels below one zeptojoule. This high level of sensitivity could potentially improve quantum computing qubit readout and the detection of dark-matter axions in astrophysics.

“The team, led by Academy Professor Mikko Möttönen at Aalto University, together with industry collaborator IQM and the Technical Research Centre of Finland (VTT), used a novel technique to achieve the milestone measurement”
CORROBORATED
Multiple sources confirm Mikko Möttönen is a Professor at Aalto University and VTT, and that IQM and VTT collaborate on quantum technology. While the specific 'below one zeptojoule' milestone is linked to the research in Claim 0, the team composition is corroborated across several sources.
