Development of the quantum processing units (QPUs) at IQM Finland Oy

Realizing large-scale quantum computers is one of the most important goals of science and technology today. It will revolutionize computing technology and push the boundaries of all fields of science. As a spinout from Aalto University and VTT, IQM focuses on the realization of a quantum computer based on superconducting circuits. Here, we present the fabricated devices and results achieved to date, which includes resonators with high-quality factors > 2e6, long qubit lifetime > 0.07 ms, and 3D integration techniques such as airbridges.
