SOLUTIONS

" When you measure qubits you want to have a large bandwidth, very low noise and you dont want to have interference from the pump. The QET TWPAs solves all these three problems."

QET Vidar TWPA Model S/D

QET three-wave mixing TWPAs are designed to give you the widest relative bandwidth and high signal-to-noise performance.

*The band can be designed for other frequencies

Near-Quantum-Limited Noise Over a 4 GHz Band

Our patented dispersion engineering and three-wave mixing enable 4 GHz of uninterrupted gain with added noise below 1 photon—approaching the theoretical quantum limit.

Two Models for Flexible Deployment

Model D: Two TWPAs combined in the same enclosure, perfect for multi-channel measurements or advanced setups that benefit from dual amplification in a single box.
Model S: A single TWPA in one compact enclosure, ideal for setups needing a straightforward, high-performance amplifier with minimal footprint.

Pump Frequency Outside the Gain Band

By placing the pump frequency (around 12 GHz) well outside the gain band, we minimize interference with measured signals, ensuring cleaner data and simpler filtering.

Simple Flux Bias

Provides both flux biasing via the internal coil, and protection from external flux.

Built-in Protection

The solution has inbuilt flux protection and ESD protection, ensuring an easy-to-use solution
