Cryogenic Interconnects and RF Solutions for Quantum Computing

XGY Tek supplies cryogenic-compatible RF interconnects, attenuators, isolators, and waveguide assemblies used inside dilution refrigerators for superconducting and spin-qubit experiments. The range is suited to quantum R&D teams, university laboratories, and cryogenic wiring projects that need defined thermal-load and RF-performance requirements.

The engineering input should include line count, drive/readout/bias role, thermal stage from 10 mK to 300 K, DC to 40 GHz signal path where applicable, conductor material, attenuation distribution, connector family, bracket geometry, phase-matching need, shielding target above 100 dB where specified, and whether S-parameter files are required by line.

Acceptance evidence should record thermal anchoring plan, line labels, room-temperature S-parameters, validation method, installation notes, and the final refrigerator wiring tree. For wiring-tree planning, see our cryogenic quantum interconnect guide.

Characterization data and acceptance requirements are confirmed during quotation.

Frequently Asked Questions

What XGY cryogenic interconnects are available?
Our cryogenic series spans DC-40 GHz coaxial interconnects engineered for ultra-low thermal conductivity (typically under 50 uW per line at mK stages), high-isolation shielded coax for readout chains, and waveguide assemblies for mmWave qubit drive. Custom attenuation, line counts, and connector configurations are quoted per project. Share refrigerator stages, line counts, and signal types with our team for a tailored proposal.
Which quantum-computing platforms are XGY components compatible with?
XGY cryogenic interconnects are compatible with standard dilution refrigerators (Bluefors, Oxford, Janis) and integrate with the major qubit control platforms used in superconducting transmon, fluxonium, spin-qubit, and ion-trap experiments. Connector pitch and bracket geometry are matched to your refrigerator brand during the quote phase.
How does XGY ensure low thermal load on dilution refrigerators?
Each line is engineered with stainless-steel and NbTi conductor combinations selected per refrigerator stage (50 K, 4 K, still, cold plate, mixing chamber). Attenuation is distributed across stages to minimize thermal loading while maintaining qubit readout SNR. For new programs, our Custom Automation team can co-design the cryogenic wiring tree alongside the room-temperature instrument rack.
When should phase-matched cryogenic lines be requested?
Request phase matching when several drive or readout channels need controlled timing or phase relationship. The quote should state frequency band, channel count, matching tolerance, labels, and the delivered evidence file.
What should be kept after cryogenic wiring installation?
Keep the wiring tree, serial labels, connector map, attenuation plan, stage anchoring notes, S-parameter files, installation photos, and any deviations found during cooldown or signal validation.
