Announcement overview Helium is a system optimized for quantum error correction from the processor and wiring to control electronics and the software stack. The current configuration assumes encoding a logical qubit with 18 cat qubits, and the design is compatible with a future 48‑cat‑qubit chip that could carry multiple logical qubits. Operational power consumption is approximately 40 kW. The management and monitoring interface “Starboard” lets operators manage system behavior, individual qubit performance, workloads, and hardware metrics from a single screen. For HPC integration, it supports major schedulers such as Slurm via the open‑source QRMI library. Helium can be instructed from the company’s dedicated software framework “Felis,” and it maintains compatibility with major quantum programming frameworks. The company is inviting research partners to participate in experiments and collaborative research.
