In the pursuit of scalable quantum computing, Quantum Enabling Technologies (QET) provide the essential hardware foundation. At 202Q-lab, the QET team focuses on designing, developing, and optimizing components that support quantum experiments, ranging from signal routing to amplification and system calibration.

Our Research

The team’s work centers on two key building blocks: quantum superconducting switches and quantum amplifiers, while also contributing to essential infrastructure tasks such as noise-temperature calibration, quasiparticle detector dynamics, and quantum filters.

Quantum switches are used to route signals between different parts of a quantum circuit, allowing multiple channels to share a single line. These switches play a crucial role in managing complex systems. At 202Q-lab, researchers are working toward smaller switches that do not dissipate heat when integrated in the cryostat—an important step toward scalable quantum hardware. By building these switches also from superconductors, we aim to simplify integration with superconducting qubits and massively boost scalability. The switches are designed and characterized at Chalmers, and built in collaboration with partners across Europe.

Quantum amplifiers ensure that even the faintest quantum signals can be reliably read out without compromising the information they carry. The team is developing and refining the Kinetic Inductance Traveling-Wave Parametric Amplifier (ki-TWPA) by exploring different materials and circuit designs to achieve optimal performance. These devices are fabricated at the Myfab Chalmers cleanroom facility.

In addition to this, the team supports the wider experimental effort through work on noise sources, hybrid superconducting-semiconducting devices, and microwave engineering—all essential for pushing the boundaries of quantum technologies.
