| Why Control Chain Matters | 01 Precise Control Begins Long Before the Qubit.Superconducting qubits are manipulated by carefully engineered microwave pulses. Any impedance mismatch, thermal noise, insertion loss variation, or cable instability can distort pulse envelopes, reduce gate fidelity, and introduce calibration drift. HQubit optimizes the complete microwave control chain to ensure every pulse arrives at the quantum processor with maximum accuracy, minimum thermal load, and exceptional long-term stability. |
Thermalization Plates | 02 Efficient Thermal AnchoringMicrowave cables continuously conduct heat into lower-temperature stages. HQubit's thermalization plates maximize thermal contact efficiency, ensuring rapid heat extraction while maintaining stable cable routing and minimizing thermal gradients. |
| High-Density Microwave Chains | 03 High-Density Microwave ChainsHQubit provides multiple high-density microwave interconnect solutions for different cryogenic platforms. From traditional SMA architectures to SSMP and SMP3 high-density assemblies, the wiring system significantly reduces installation space while supporting hundreds of microwave channels. |
| Cryogenic Attenuators | 04 Cryogenic Attenuators： Thermal Noise SuppressionMicrowave attenuation at multiple temperature stages is essential for reducing Johnson noise propagating from room temperature into the quantum processor. HQubit cryogenic attenuators provide stable attenuation under cryogenic conditions while serving as highly efficient thermal anchors. |
High-Attenuation Infrared Filters | 05 High-Attenuation Infrared Filters Broadband Infrared SuppressionThermal photons generated at higher temperature stages are one of the dominant sources of quasiparticle poisoning and qubit decoherence. HQubit high-attenuation infrared filters effectively suppress broadband blackbody radiation while maintaining controlled microwave attenuation for qubit control signals. |
| Cryogenic Low-pass Filters | 06 Cryogenic Low-pass FiltersHQubit's low-pass filters remove unwanted high-frequency noise from control and bias lines, improving gate stability. |
| Why HQubit | 07 Why HQubitRather than relying on individually selected components, HQubit engineers the entire microwave control chain as a unified cryogenic platform, ensuring optimized electrical performance, thermal stability, and mechanical reliability across every temperature stage. |
