Alice & Bob Launches Helium Multi-Cat-Qubit Platform for Third-Party Quantum Error Correction Experiments

Alice & Bob has made its Helium platform available to third-party organizations, marking the first multi cat-qubit system offered externally for quantum error correction research and experimentation. The compact 18-qubit system integrates noise-biased cat qubits with degree-2 connectivity and delivers bit-flip times exceeding one hour along with 94.2% Z-gate fidelity in 26.5 nanoseconds. Backed by €130 million in total funding and a new $50 million Paris laboratory, the company is advancing a clear roadmap toward a 100-logical-qubit Graphene quantum computer by 2030. The platform’s design aims to reduce physical qubit overhead for fault-tolerant quantum computing by up to 200 times compared with conventional superconducting approaches. Researchers can now access this hardware-efficient architecture through a unified control interface for collaborative experiments.

Horizon Quantum Selects Dublin for Second Quantum Computer Testbed with IonQ 256-Qubit Trapped-Ion System

Horizon Quantum is establishing its second quantum computer testbed in Dublin, Ireland, equipped with an IonQ 256-qubit trapped-ion system. This deployment at the company’s European headquarters aims to leverage Ireland’s quantum ecosystem and talent pool while advancing the company’s hardware-agnostic software capabilities through the Triple Alpha environment. The initiative follows a similar superconducting testbed in Singapore and aligns with Ireland’s Silicon Island National Semiconductor Strategy. Government support from figures like Minister Peter Burke and IDA Ireland CEO Michael Lohan highlights the strategic importance of this investment. CEO Dr. Joe Fitzsimons emphasized the step forward for both the company and Ireland’s quantum sector.

Alice & Bob Proposes Five-Criteria Framework to Benchmark Logical Qubit Claims

Alice & Bob has published a whitepaper defining five criteria to benchmark logical qubit claims. The framework provides a modality-agnostic way to evaluate demonstrations of quantum error correction for fault-tolerant quantum computing. Key requirements include achieving breakeven with physical qubits, using scalable code parameters, running sufficient QEC cycles, measuring performance across all runs without post-selection, and operating on utility-relevant timescales. This structured approach enables consistent comparisons across hardware modalities and aligns claims with practical FTQC needs.
