QiB1 and QiB2 Superconducting Platforms Advance Quantum Hardware Research at ConScience AB

ConScience AB

The better, reproducible clean-room production procedures of ConScience AB have produced two key superconducting qubit devices, QiB1 and QiB2. These gadgets should boost quantum hardware research and development. These platforms are made for researchers to construct benchmarking and calibration tools. March 13, 2025 saw the two devices announced. November 13, 2025 brought more QiB2 superconducting qubit platform availability details.

Following the success of the company's initial product, QiB0, in 2024, the latest gadgets meet quantum researchers' growing needs. These gadgets are expected to aid quantum computing applications in complicated sectors including financial modelling, drug discovery, and cryptography.

Dedicated Superconducting Qubit Characterisation Devices

The QiB1 and QiB2 devices offer superconducting qubit exploring functions. Later reports stated that the QiB2 was developed at ConScience AB's facilities in Gothenburg, Sweden, and housed in the company's new Box20 packaging, but both devices were originally packaged in Box16 for durability and smooth integration into research setups.

QiB1 has six qubits. It supports flux-tunable and fixed-frequency qubits for flexible single-qubit testing. The floating and shunted transmon qubits need redundancy characterisation, which QiB1 gives.

The seven-qubit QiB2 gadget focusses on advanced two-qubit coupling research. Initial reports indicated it had fixed and adjustable frequency couplers. This technology allows advanced coupling research, which are necessary to understand complex quantum interactions.

Mastering Coupling and Control on QiB2

On November 13, 2025, the QiB2 platform was launched to accelerate quantum hardware research and education. The adaptable superconducting qubit "playground," the QiB2, lets researchers methodically explore qubit coupling to study fixed- and tunable-frequency qubits and couplers. This configuration is necessary for benchmarking performance and noise sensitivity and experimenting with different gate types.

It integrates several key components into a deployable device:

Basic building components are bare coplanar resonators.

Dedicated drive and flux lines provide tight control of single, tunable transmon qubits.

Qubit couplings.

Scaling up to more complex multi-qubit systems after characterising qubit performance using this integrated technique is essential to constructing viable quantum processors.

Powerful diagnostics and integration QiB2's significance lies in its integrated design, which prioritises qubit coupling knowledge above acquisition. The system provides two coupled-qubit configurations for side-by-side evaluation of parametric and on-resonance gate families.

Some setups are:

Fixed coupler-tunable qubit pairs.

Adjustable couplers connect fixed-frequency qubit pairs.

This purposeful design allows researchers to compare control fidelity, performance, and noise sensitivity in the same hardware, revealing minute changes in fidelity and resilience that are critical for quantum circuit design.

In addition to qubit capabilities, the QiB2 is a good diagnostic tool. Different variations are sensitive to noise and cryogenic installation faults. Because of this, the QiB2 is ideal for testing overlooked system components such control software, shielding, filtering, and microwave wiring. Quantum research and the building of new quantum labs are simplified by the QiB2's straightforward diagnostic tool for diagnosing and addressing systemic faults and reliable experimental platform.

Education and workforce development acceleration

The QiB2 platform was designed for learning and teaching. The modular design of superconducting quantum circuits helps students and researchers learn the basics. Users can methodically study structures from simple resonator studies to adjustable and fixed-frequency transmon qubits to paired-qubit interactions.
