Our technology

We apply advanced semiconductor fabrication and integration to solve scaling bottlenecks—reproducible qubit yield and component integration.

1  Semiconductor-compatible qubit fabrication

Qolab developed a semiconductor-compatible window-junction process that replaces lift-off fabrication with subtractive etching, creating atomically clean interfaces. Designed for 300 mm semiconductor tools, the process enables reproducible, high-yield superconducting qubit fabrication across full wafers.

2  Wafer-scale integration architecture

By adapting wafer-scale integration and advanced semiconductor packaging, Qolab bonds qubit and wiring wafers into modular tiles. Integrated cryogenic interconnects, filters, and amplifiers reduce discrete components and enable dense, scalable quantum processor architectures.

Our partnerships

Qolab partners with leading semiconductor companies, government programs, and research institutions to adapt advanced fabrication technologies for superconducting quantum hardware.

Our product

Qolab Start is Qolab’s first deployable superconducting QPU platform for reliable hardware research and workforce development, available on-premise or via cloud access.

1  Turn-key experimental platform

Engineered for stable, high-fidelity experiments with carefully designed packaging, wiring, filtering, and shielding—so researchers can trust their data from day one.

2  High-quality qubits

Processors and resonators fabricated and characterized in-house by Qolab, providing researchers with a reliable benchmark for validating system performance.

3  Pulse-level hardware control

Direct access to microwave and flux pulses enables real-time qubit manipulation, calibration workflows, and advanced quantum control experiments.

4  Parallel research with multi-device loading

Load and switch between up to six devices in a single cooldown—enabling parallel research, benchmarking, and education on shared infrastructure.
