Arctic Instruments announces the release of AI-TWPA-C-M, a compact, pre-assembled travelling wave parametric amplifier (TWPA) module designed for cryogenic microwave readout applications.
The AI-TWPA-C-M combines the AI-TWPA-C with two double-junction isolators and magnetic shielding in a mechanically integrated module. Each unit is delivered wired, tested, and ready to plug in. To further simplify system integration, we provide factory-calibrated cryogenic bias parameters (flux bias, pump frequency, and pump power). These parameters are cryostat independent and stable over time.
Designed to eliminate integration uncertainty
Reading out extremely weak microwave signals, whether from superconducting qubits or cavity-based axion or graviton detectors, depends critically on the first amplification stage. This first stage is also very sensitive to implementation details: component choice, component order, cabling, magnetic shielding, and mechanical mounting all matter. Small and easily avoidable mistakes reduce performance and debugging costs time, due to long cooldown cycles.
The AI-TWPA-C-M reduces setup time and common failure modes by having the most critical connections designed and preassembled according to our best practices, informed by our experience in characterizing hundreds of TWPAs. We developed AI-TWPA-C-M to enable quantum-limited microwave readout to be brought up quickly and reliably, without requiring extensive previous experience with TWPAs.
Compact and scalable
In qubit readout applications, the isolators integrated in AI-TWPA-C-M protect the qubits from back-propagating noise and also provide the impedance matching and directivity required for stable TWPA operation.
The compact form factor allows straightforward installation in crowded cryostats and supports stacking several AI-TWPA-C-M’s in scaled-up systems. Thanks to the modular nature of AI-TWPA-C-M, any number of readout lines can be implemented easily, without a need to design magnetic shields or complex mounting structures for a specific number of readout lines.
Wideband performance without stop bands
The underlying AI-TWPA-C uniquely offers an exceptionally wide bandwidth from 4.5 GHz to 9.5 GHz, without stop bands in between, enabling flexible multi-frequency readout architectures.
