Intel teams for huge Japanese quantum computer

Intel has signed a deal with a research lab in Japan to develop large scale quantum computer systems with tens of thousands of qubits.
A Memorandum of Understanding (MoU) with the National Institute of Advanced Industrial Science and Technology (AIST) will see the development of an evaluation testbed at the Quantum-AI Fusion Technology Business Development Global Research Center (G-QuAT) using devices built on Intel’s quantum processor technology.
The aim is to build a system with tens of thousands of quantum bits at an industrially usable level by the early 2030s.
Intel aims to produce scalable silicon-based quantum processors
Intel has already developed a quantum processor called Tunnel Falls for researchers using a quantum dot process to create spin qubits that can be implemented in commercial CMOS on 300mm wafers with 95% yields, making it commercially viable.
AIST and Intel will build on the Tunnel Falls development, working on new materials for the quantum dots and the implementation technologies as well as improving the refrigeration technology for large-scale quantum computers along with the cryoelectronics for quantum bit control.
Intel is also working on technology to run spin qubit quantum processors at warmer temperatures than close to absolute zero. It has also developed a cryogenic quantum control chip called Horse Ridge II that provides tighter integration of quantum processors and a cryoprobe that enables high-volume testing to accelerate commercialization.
US startup PsiQuantum is also aiming to produce a quantum computer with millions of qubits using photonic technology built with GlobalFoundries.
