Finnish Researchers Say Their First Quantum Computer Is Up and Running

(Bloomberg) Finland’s first quantum computer was commissioned at the VTT Technical Research Centre near the capital Helsinki, where scientists will use it to study next-generation computing power.
The 5 quantum-bit computer was developed “to learn how to build a quantum computer, how to program one and how to operate one in the future,” Pekka Pursula, research manager at the VTT Technical Research Centre. The machine was the joint work of VTT and quantum computing hardware company IQM Finland Oy.
“This 5-qubit computer has relatively low computational power, and it’s not enough to solve practical problems,” Pursula said. The researchers plan to build a 50-qubit machine by 2024 that could be used for applications such as modeling viruses and drugs, and designing materials that today’s technology is ill-equipped to handle.
What remains to be solved by researchers globally are scalability and improving coherence — keeping qubits in quantum state so that errors don’t creep into the calculations.
