Towards Scalable Quantum Technology: Sweden–Singapore Feasibility Study on Novel Component Technology for Quantum Amplifiers

Purpose and goal

The project develops and tests a new generation quantum amplifier (TWPA) for superconducting quantum computers. Increased on-chip integration reduces the need for external components, lowering system complexity and making the technology a key enabler for larger and more advanced quantum systems. Together with the National University of Singapore, performance will be validated. The goal is more scalable quantum hardware and strengthened Swedish competitiveness.

Expected effects and result

The project provides independent validation of a new-generation quantum amplifier and detailed data on gain, noise, dynamic range and stability. The results will be used to refine the design and documentation, making integration into quantum labs easier. The collaboration with NUS creates a platform for joint projects, international adoption and future export of Swedish quantum technology.

Planned approach and implementation

The project is divided into four work packages. First, TWPA units are completed and tested in Sweden, including packaging, documentation and delivery to NUS. NUS then integrates the amplifier into existing cryogenic chains and performs independent measurements. Next, the data are jointly analysed and improvements to design and manuals identified. Finally, a joint validation report and basis for continued commercialization are compiled.
