HERD at a glance
Ultra-low passband loss that preserves qubit control and readout fidelity.
Blocks high-frequency noise
Prevents high-frequency radiation from reaching the sensitive qubits, reducing quasiparticle induced losses.
< 0.15 dB insertion loss
HERD has the lowest in-band insertion loss among all IR-blocking filters on the market - enabling control and readout signals to pass with negligible degradation, enabling accurate, repeatable qubit control.
Works at millikelvin temperatures
Designed for cryogenic environments. Install HERD close to the QPU (below the base plate) to minimize thermal interference and get the full benefit of high-frequency isolation.
Engineered for quantum
Non-magnetic, thermally optimized, and mechanically robust for small and large quantum systems. HERD is used by leading scientists and industry players to reach state-of-the-art qubit performance.
