Roll-Out of the QiB2 — A Superconducting Playground for Quantum Research

ConScience today announce the roll-out of the QiB2, a versatile superconducting qubit platform designed to accelerate quantum hardware research and education.

GOTHENBURG, SWEDEN, November 12, 2025 /EINPresswire.com/ -- The QiB2 in the Box20 package provides a comprehensive environment for exploring qubit coupling architectures of varying complexity — from fundamental resonator studies to multi-qubit interaction schemes — all within a single, integrated device.
Researchers can progress step by step through the key building blocks of superconducting quantum systems, including:

• Bare coplanar-waveguide resonators
• A single fixed-frequency transmon qubit driven through its readout resonator
• A single fixed-frequency transmon qubit with a dedicated drive line
• A tunable transmon qubit equipped with both flux and drive lines

When ready to move beyond single-qubit physics, the QiB2 offers two coupled-qubit configurations:

• A pair of tunable qubits connected via a fixed coupler
• A pair of fixed-frequency qubits linked by a tunable coupler

These setups enable direct experimentation with different families of two-qubit gates, such as on-resonance and parametric gates, allowing side-by-side comparison of performance, control fidelity, and noise sensitivity — all within the same platform.
Because each configuration responds differently to environmental noise and setup imperfections, the QiB2 also serves as a powerful benchmarking tool for cryogenic microwave wiring, shielding, and filtering, as well as for the development and validation of control software and hardware.
Whether you’re establishing a new quantum lab, training students and researchers, or testing cryogenic setups, the QiB2 offers a robust and flexible foundation for experimentation and learning.

Housed in the new Conscience Box20 packaging, the QiB2 integrates seamlessly into cryogenic systems and is ready for immediate deployment.
