Hybrid Quantum Amplifiers

Important results from the project

** Denna text är maskinöversatt ** Within the project, a hybrid amplifier based on semiconducting and superconducting elements has been developed, with applications in advanced quantum technology. The amplifier can be used to provide optimal readout of cryogenic quantum bits, limited only by fundamental quantum mechanical processes. The main objectives of the project have been met, and the technology has been moved from TRL2 to TRL3.

Expected long term effects

** Denna text är maskinöversatt ** Analysis and experimental results show that the component can function as intended and is possible to manufacture. However, major eligibility requirements will be placed on details during manufacturing. The component could lead to a new way to manufacture amplifiers at cryogenic temperatures that are superior to existing technologies such as parametric amplifiers and traditional semiconductor technology.

Approach and implementation

** Denna text är maskinöversatt ** The project was divided into three WPs. Inom WP1 developed the technology and electrical measurements were performed on components. WP2 concerned predictive quantum transport modeling in support of WP1. Inom WP3 developed electrical models for the component for the design of amplifing elements
