ConScience AB Uses QiB1 and QiB2 Superconducting Platforms to Advance Quantum Hardware Research
ConScience AB
Two important superconducting qubit devices, QiB1 and QiB2, have been introduced by ConScience AB, a company known for its superior, repeatable clean-room production methods. These devices are intended to greatly enhance the research and development of quantum hardware. These platforms are designed especially for researchers to create benchmarking tools and calibration methods. On March 13, 2025, the two devices were first announced. More information about the QiB2 superconducting qubit platform’s availability was provided later on November 13, 2025.
The new gadgets are designed to satisfy the increasing needs of the quantum research community, building on the success of the company’s first product, QiB0, which was introduced in 2024. It is anticipated that the deployment of these devices will facilitate developments in important applications of quantum computing, including complex fields like financial modelling, drug discovery, and cryptography.

Dedicated Devices for Superconducting Qubit Characterization
Specialized features for superconducting qubit exploration are provided by the QiB1 and QiB2 devices. Later reports about the QiB2 stated that it was developed at ConScience AB‘s facilities in Gothenburg, Sweden, and housed within the company’s new Box20 packaging, although both devices were originally reported to be packaged in ConScience’s Box16 enclosure, guaranteeing durability and smooth integration into research setups.
There are six qubits in the QiB1 gadget. It is designed to provide flexible single-qubit testing, supporting both flux-tunable and fixed-frequency qubits. Moreover, QiB1 provides redundancy characterisation that is essential for floating and shunted transmon qubits.
Advanced two-qubit coupling experiments are the main focus of the seven-qubit QiB2 device. It was initially said to have both fixed and adjustable frequency couplers. Advanced coupling investigations, which are essential for comprehending intricate quantum interactions, are made possible by this platform.
The Versatile QiB2 Platform: Mastering Coupling and Control
Specifically designed to speed up quantum hardware research and education, the QiB2 platform was unveiled on November 13, 2025. The QiB2, a versatile superconducting qubit “playground,” allows researchers to study fixed- and tunable-frequency qubits as well as fixed and tunable couplers by methodically exploring qubit coupling. This configuration is essential for benchmarking performance and noise sensitivity as well as facilitating experimentation across several gate types.
The platform combines a number of essential elements into a single deployable device:
- The fundamental construction blocks are bare coplanar resonators.
- Transmon qubits are single and tunable, and for fine control, there are alternatives for dedicated drive and flux lines.
- Arrangements of coupled qubits.
A crucial step in creating workable quantum processors is scaling up to more intricate multi-qubit systems after thoroughly characterizing the performance of individual qubits using this integrated technique.

Integrated Configurations and Diagnostic Power
The QiB2’s real value is found in its all-encompassing, integrated design, which prioritises a thorough knowledge of qubit coupling over merely obtaining it. Two different coupled-qubit configurations are offered by the system, enabling direct side-by-side comparison of various gate families, including parametric and on-resonance gates.
Among the configurations are:
- Tunable qubit pairs connected by a fixed coupler.
- Fixed-frequency qubit pairs connected by a coupler that can be adjusted.
Researchers may evaluate control fidelity, performance, and noise sensitivity side by side inside the same hardware this intentional design, which highlights minute variations in fidelity and resilience that are crucial for improving quantum circuit design.
The QiB2 is an effective diagnostic tool in addition to its core qubit capabilities. Its numerous variants show varying sensitivity to noise in the surroundings and flaws in cryogenic installations. Because of this, the QiB2 is perfect for verifying important system elements that are frequently disregarded, like control software, shielding, filtering, and microwave wiring. The QiB2 ultimately simplifies quantum research and the creation of new quantum labs by offering a clear diagnostic tool for detecting and fixing systemic problems, providing a solid platform for experimentation.
Accelerating Education and Workforce Development
The QiB2 platform was created especially to be a great learning and teaching tool. Students and researchers can gradually master the fundamentals of superconducting quantum circuits its modular design. From simple resonator studies to tunable and fixed-frequency transmon qubits and finally to paired-qubit interactions, users can methodically investigate structures.
The QiB2 offers practical expertise with the essential components of quantum computation by providing hands-on experience with various qubit types and coupling schemes, including working with gate families such as on-resonance and parametric gates. This pragmatic, integrated strategy is crucial for speeding up workforce development required for the quickly changing field of quantum technology. ConScience AB is still committed to producing high-quality, repeatable products in order to support these advancements.
