Techniques facilitating increased operational reliability for jib cranes are provided. In one example, a jib crane can comprise a mast, a shaft mechanism, and a rod. The mast can extend vertically from a base structure. The shaft mechanism can be disposed within the mast. The rod can be coupled to a boom arm and can be disposed within the shaft mechanism. Rotation of the rod can facilitate continuous rotation of the boom arm about a longitudinal axis of the rod with respect to the base structure.

The technology described herein is directed towards microwave attenuators, and more particularly to a cryogenic microwave attenuator device for quantum technologies. In some embodiments, a device can comprise a cryogenic microwave attenuator device. The cryogenic microwave attenuator device can comprise: a housing component and a microwave attenuator chip, wherein the housing component can have thermal conductivity of about at least 0.1 Watts per meter-Kelvin at 1 degree Kelvin. The cryogenic microwave attenuator device can also comprise a microwave connector comprising a signal conductor that is direct wire coupled to the microwave attenuator chip.
