Welcome to the world of next-generation signal amplification with wideband quantum-limited amplifiers (QLA).
Amplifiers play a crucial role in boosting signals for various applications, and QLAs take this to new heights. Whether it is enhancing satellite communication, exploring the cosmos with radio astronomy, or decoding quantum information in quantum computing, the QLA is your go-to solution.
A quantum-limited amplifier (QLA) is an amplifier that, unlike conventional low-noise amplifiers (LNAs), only adds the minimum amount of noise when amplifying. This is especially important when amplifying very small-amplitude signals, such as the qubit readout in a quantum computer. The quantum-limited noise performance is achieved by using a superconducting parametric amplifier. These amplifiers have the ability to give quantum-limited noise performance due to their inherently small losses and the parametric amplification process. Unlike conventional amplifiers that rely on active components, parametric amplifiers harness the nonlinear behaviour of specific components or materials.
Superconducting Travelling-Wave Parametric Amplifiers (TWPAs) represent a sophisticated class of parametric amplifiers renowned for their ability to enhance signals across a wide range of frequencies while giving quantum-limited noise performance.
As technology advances, TWPAs continue to play a vital role in enabling breakthroughs in various fields by ensuring clear, reliable signal processing across diverse frequency spectra.
Our solution is a TWPA, a cryoperm shield, a local coil and pump coupling, all in one package. This gives amplification with near-quantum-limited noise performance, while minimising the thermal load to your cryostat, the required space in the fridge and the number of components.
