Alice & Bob Announces On-Premises Quantum System “Helium” Featuring 18 Cat Qubits
On June 10, 2026, Alice & Bob announced the on-premises “Helium Quantum System.” It is designed to encode the company’s first logical qubit using 18 cat qubits, and the company aims to offer it to research institutions as an integrated system that includes control hardware, a monitoring interface, and software.
※Cat qubit(cat qubit) refers to a qubit that uses a Schrödinger cat state (cat state), and is a technology that could significantly reduce the hardware scale required for quantum error correction. The concept of cat qubits predates Alice & Bob, but the company has developed a practical superconducting-circuit implementation of an approach that suppresses bit-flip errors at the physical level and is commercializing it as a core technology for FTQC.
Overview
Helium is a system optimized for quantum error correction from processors and wiring to control electronics and software stacks. The current configuration assumes encoding a logical qubit using 18 cat qubits, and it is designed to support a future 48-cat-qubit chip that could host multiple logical qubits. The operating power consumption is approximately 40 kW. The management and monitoring interface “Starboard” allows users to manage system behavior, individual qubit performance, workloads, and hardware metrics from a single screen. For integration with HPC environments, it supports major schedulers such as Slurm via the open-source QRMI library. Commands for Helium can be issued from the dedicated software framework “Felis”, and the company says it will maintain compatibility with major quantum programming frameworks. The company is inviting research partners to participate in experiments and collaborative research.
Key Points
- Designed to encode the company’s first logical qubit using 18 cat qubits
- Integrates processors, control systems, and software with quantum error correction in mind
- Adopts a configuration that can be upgraded to a 48-cat-qubit chip
- Centralizes management of qubit performance, workloads, and operational metrics via “Starboard”
- Anticipates integration with HPC schedulers and major quantum development environments via QRMI and Felis
Technical and Business Implications
On the technical side, the significance lies in expanding focus from chip development for cat qubits to a system that includes the control systems and software needed for experiments with logical qubits. It could serve as a foundation for researchers to study quantum error correction and the integration of quantum and classical compute resources on real hardware. However, the announcement does not provide logical-qubit error rates or operational performance. On the business side, this move creates touchpoints with HPC centers and research institutions as a completed system intended for on-premises deployment. At the same time, the timing, price, deployment sites, and research partners have not been disclosed, so the concrete scale of deployment cannot be judged at this time.
What to Watch
First, the focus will be on whether measured performance of the logical qubit realized with 18 cat qubits and the error-suppression effect compared to physical qubits are presented. In addition, the timing and price of availability and the specific nature of experiments to be conducted with research partners will be material for assessing its commercial potential. It will also be important to watch upgrades to a 48-cat-qubit configuration and operation of multiple logical qubits, as well as real-world operational experience in HPC environments.
✍️ Quantum Index Analysis
The value of this announcement lies not in the “18 cat qubits” themselves, but in the fact that Alice & Bob has moved to the next stage from chip developer to system vendor. Until now the company has primarily communicated research and development on cat qubits, but this time it has unveiled “Helium”, an integrated system that includes the refrigerator, control hardware, software, and operational tools. Providing an on-premises environment that can actually be operated by research institutions and HPC centers signals an intent to demonstrate maturity not just of the architecture but of the system, which is noteworthy.
On the other hand, the advantage of cat qubits is not determined solely by the characteristics of the individual device. It will be important to see to what extent the low-error properties and the efficiency gains in error correction are maintained when integrated into a system, and the roadmap of “realizing a logical qubit with 18 cat qubits” will be judged in future by demonstration data showing actual logical error rates and overall system performance.
