Scientists Can Measure Tiniest Energies in Superconducting Circuits

Monday, January 20, 2020 - 15:22

Teams of researchers from Aalto University and Lund University have taken an essential step for quantum technology through developing a new device which can measure the tiniest energies in superconducting circuits.

According to the Science Daily report, Doctoral student Bayan Karimi, works in QTF and Marie Curie training network QuESTech, developed a device which measures the heat in a system.

It uses a strip of copper about one thousand times thinner than a human hair. 'Our detector absorbs radiation from the quantum states. It is expected to determine how much energy they have and how they interact with their surroundings. There is a theoretical limit to how accurate a calorimeter can be, and our device is now reaching that limit', says Karimi.

New research published in Nature Communications from teams at Aalto University and Lund University hopes to provide an important tool in quantum technology.
