APITech Cryo Attenuators

Quantum computing has the power to change our understanding of the world. But to function properly, quantum computers depend on cryogenic refrigeration systems that may require thousands of coaxial attenuators. APITech’s newest attenuators, tested to 4mK, support these leading edge tools. Just one example of the quality, reliability and innovation of our coaxial attenuators. .
