Cosmic rays or radioactivity affect quantum bits, which impacts quantum calculation time.

The path to quantum supremacy is made challenging by the issues associated with scaling up the number of qubits. One key problem is the way that qubits are measured. Aalto Professor Mikko Möttönen and his Quantum Computing and Devices (QCD) research group introduce a new approach that tackles these challenges head-on using nanobolometers instead of traditional, bulky parametric amplifiers.

Aalto University researchers are the first in the world to measure qubits with ultrasensitive thermal detectors—thus evading the Heisenberg uncertainty principle. Chasing ever-higher qubit counts in near-term quantum computers constantly demands new feats of engineering. Among the troublesome hu
