Xanadu Selects VTT Technical Research Centre of Finland as One of their Manufacturing Partners

One of the most strategic decisions a quantum hardware company can make is how they plan to manufacture their chips. Some companies, such as Rigetti, have decided to construct their own fabrication facility in order to obtain the best possible control and fabrication turn-around time. While others, including D-Wave, PsiQuantum, and others are utilizing semiconductor foundries to build their chips. Xanadu has decided to take the latter approach, but it appears they will be using multiple vendors for different parts of their system. In August, they announced they will partner with imec in Belgium to fabricate the chips that contain the photonic qubits based on imec's ultra-low loss silicon nitride (SiN) waveguides. But to complete the design, they also need sensitive photon detectors to count the qubits when they come out at the end of the silicon nitride waveguide chips. For this, they have selected the VTT Technical Research Centre of Finland as their vendor. VTT will be using a superconducting photon detector technology to build these devices for Xanadu which Xanadu will use in their development of a fault tolerant quantum computer. You can view VTT's announcement that they have been selected as a vendor to Xanadu in a news release available on their website here.
