VTT and IQM launch 50-qubit computer
The VTT research institute and IQM Quantum Computers have completed the development of a 50-qubit superconducting quantum computer.
The 50-qubit quantum computer is located at VTT’s premises in Micronova in Espoo, Finland. Its creation marks the culmination of four years of joint development and the computer is available for research and business use through the VTT QX quantum computing service.
The development of the machine has been backed by the Finnish government with €20.7 million under the terms of a national quantum computing project announced in November 2020. The latest announcement follows on from a 5-qubit quantum computer completed in 2021 and a 20-qubit computer was completed in 2023.
VTT especially developed the superconducting traveling wave parametric amplifiers (TWPAs), used for readout of the qubit signals, as well as quantum processor chip-level integration and packaging solutions. The superconducting TWPAs developed and manufactured by VTT are currently the world’s leading components, and they are in demand within the quantum technology industry in Europe. VTT’s spin-off company, Arctic Instruments, is commercializing VTT’s TWPA technology.
“Leadership in critical technologies like quantum computing is crucial for Finnish society. We need to be capable of both building the required hardware as well as using it for practical applications,” said Erja Turunen, executive vice president of VTT, in a statement.
“Now with the 50-qubit quantum computer completed, it is time for the applications development by the entire Finnish ecosystem,” she added.
Jan Goetz, co-CEO of IQM Quantum Computers, said: “Our collaboration with VTT to develop the 50-qubit system serves as a baseline for our IQM Radiance 54-qubit quantum computer, a product we are shipping to our customers worldwide.”
VTT is also manufacturing services around qubits including the Josephson junction technology, superconducting through silicon vias (TSVs) and superconducting flip chip integration methods. During the innovative 50-qubit quantum computer co-development, VTT also launched another quantum technology spin-off, SemiQon, which is developing semiconducting qubits.
