Intel Creates First Cryogenic Control Chip for Quantum ComputingIntel Labs has unveiled a new cryogenic control chip designed to speed up the development of full-stack, commercially-viable quantum computers capable of processing multiple qubits. Intel feels confident that this breakthrough takes us one step closer to quantum computing, which could, for example, significantly advance medical practices. However, silicon qubits would allow them to function at higher temperatures (1-Kelvin or more), meaning the required refrigeration process could be simplified for those quantum systems. Image from Intel To overcome the problem, engineers created redundancies, using a number of qubits and housing them in cryogenically-controlled chambers calibrated at near absolute zero. With Horse Ridge, Intel has developed a scalable control system that will allow us to significantly speed up testing and realize the potential of quantum computing. FinFET Technology Process Intel collaborated with engineers from quantum computer research conglomerate QuTech, who helped fabricate the Horse Ridge chip using Intel’s 22nm Under the hood, the Horse Ridge chip is a mixed-signal SoC (System on Chip) that acts as an RF processor and controls the qubit states within a 4-Kelvin freezer.
