Arctic Instruments
Arctic Instruments provides the AI‑TWPA‑C, a three‑wave‑mixing traveling‑wave parametric amplifier that delivers near‑quantum‑limited noise (< 1 photon, ≥ 70 % quantum efficiency) over a continuous 5 GHz bandwidth without stop bands. The amplifier integrates a superconducting pump coupler and on‑chip flux bias line, eliminating external couplers and bulky bias coils, which reduces insertion loss by up to 1 dB and simplifies setup. Plug‑and‑play SMP and MMCX connectors with supplied cables, high dynamic range, and stable performance across cooldowns lower total cost of ownership for quantum‑hardware developers and research labs.

Problem
Superconducting qubit readout and high‑Q resonator measurements require microwave amplifiers with near‑quantum‑limited noise, wide bandwidth, and stable performance, but existing traveling‑wave parametric amplifiers (TWPAs) often need external pump couplers, bulky bias coils, and exhibit limited bandwidth or stability, increasing system complexity and cost.
Solution
Arctic Instruments offers the AI‑TWPA‑C, a three‑wave‑mixing traveling‑wave parametric amplifier that delivers added noise below one photon (≈70 % quantum efficiency) across a continuous 5 GHz bandwidth without stop bands. The device integrates a superconducting pump coupler and on‑chip flux bias line, eliminating external couplers, reducing insertion loss by up to 1 dB, and simplifying biasing. SMP and MMCX connectors with supplied cables provide plug‑and‑play integration. High dynamic range and repeatable performance from cooldown to cooldown reduce tuning effort and total cost of ownership, while detailed setup guides and per‑unit test reports ensure users can verify specifications quickly.
Target Audience
Primary customers are quantum‑hardware developers and research labs that need high‑fidelity dispersive readout for superconducting qubits (e.g., transmon, fluxonium) and low‑power, high‑Q resonator characterization in circuit QED systems.
Features
- Near‑quantum‑limited added noise (< 1 photon) corresponding to ≥ 70 % quantum efficiency at the amplifier input
- Continuous 5 GHz bandwidth with no stop bands and high dynamic range
- On‑chip superconducting pump coupler removes external coupler and cable, saving 0.5–1 dB insertion loss
- Integrated on‑chip flux bias line for uniform, repeatable magnetic bias without macroscopic coils
- SMP RF connectors (signal in/out, pump) and MMCX bias connectors with all required cables supplied
- Comprehensive installation guide, intermediate reference measurements, and per‑unit test report for performance verification
- Stable operation across multiple cooldown cycles, reducing tuning complexity and total cost of ownership
