1st Generation
HERD-1
First-generation high-energy radiation drain
A passive, non-magnetic inline filter that drains high-energy radiation away from the signal path while leaving microwave signals essentially untouched. Ideal for readout, drive and bias lines placed close to the quantum processor.

Why HERD-1
Proven IR blocking
HERD-1 established the foundation of our patented infrared-blocking technology, demonstrating effective high-frequency attenuation while preserving signal integrity in the microwave band.
Research validated
Deployed in quantum computing research labs worldwide, HERD-1 has been instrumental in advancing our understanding of quasiparticle dynamics and coherence improvement strategies.
Simple integration
Standard SMA inline form factor allows direct installation on readout, drive, and bias lines without modifications to existing cryostat wiring configurations.
Designed for your
quantum stack
HERD-1 is optimized for installation on signal lines closest to your quantum processor, where infrared radiation poses the greatest threat to qubit coherence.
- Readout lines for dispersive measurement
- Drive lines for qubit control pulses
- Bias lines for flux tuning
- Research and development setups
