An IR Filter protects sensitive quantum devices from high-energy photons that might cause unwanted heating or decoherence.
The coaxial Infrared Filter (IR Filter) blocks infrared radiation, while still enabling high signal fidelity within the DC – 6 GHz passband, where it is optimized for low return loss and low insertion loss.
The IR Filter protects sensitive quantum devices that operate below 1 K from high-energy photons that can cause unwanted heating or decoherence. In addition, it improves the thermalization of the center conductor in a coaxial line.
The IR Filter has connectors that can be thermally anchored to the Bluefors RF Installation Set, or enable its use as an adapter between coaxial cables.
A common application of the IR Filter is in superconducting qubit devices where infrared radiation is suspected to generate quasi-particle excitations that reduce the coherence time of the qubit.
