Cryogenic Quantum Computing Interconnect Solutions

Radiall Cryogenic Quantum Computing Interconnect Solutions include cable assemblies, attenuators, and coaxial switches ideal for various applications. The semi-rigid cable assemblies use proprietary/specific technologies to tolerate lower temperatures up to tens of mK, and these technologies have been tested in the laboratory and the field. Due to space constraints, miniature and multi-coaxial connectors with semi-rigid cables are vital in quantum computing. RF attenuators are used in different stages of the thermal dilution refrigerator, reducing the thermal noise in the signal. The signal-to-noise ratio (SNR) increases due to the RF lines within each layer, requiring the attenuator for the thermalized layer to protect the signal level. Radiall cryogenic switches function at extremely low temperatures (-273°C) and actuate at low power. The switches can be easily integrated into equipment and are an ideal solution for various laboratory applications.
