They published resource estimates for Shor’s algorithm using cat qubits and LDPC‑cat codes, estimating RSA‑2048 could be broken in 3.14 days.
In the first phase of France’s PROQCIMA program, they tested cat‑qubit CNOT gates and a distance‑3 repetition code on hardware. The logical error rate remains above the error‑correction threshold.
Alice & Bob performed a proof‑of‑concept decoding of LDPC‑cat codes on a GPU via NVIDIA NVQLink. The test used synthetic data and did not achieve real‑time decoding.
Alice & Bob and ENS Lyon demonstrated a method to control two-photon dissipation in superconducting cat qubits using a tiny DC voltage instead of microwave drives.
Independent evaluation of 36 quantum industry companies across technology, business results, QEC, manufacturing capability, customers and revenue. The Autumn 2026 edition adds nine firms — including Quantum Machines, Bluefors, Qblox and Riverlane — and analyzes ranking shifts since the summer edition and changing competitive axes in the quantum industry.
Alice & Bob and CEA have begun work to integrate software for cat qubits into HPC environments and to research many-body algorithms aimed at early fault-tolerant quantum computing.
Xanadu has added Backline to PennyLane to integrate control of CPUs, GPUs, FPGAs and quantum processors from a single interface, claiming end-to-end communication latency under 3 microseconds.
Alice & Bob and Hyperion Research recommended latency testing, software standardization, and joint workflow design to integrate HPC, quantum, and AI.
Alice & Bob has joined the European doctoral network QuBriC, providing expertise in quantum error correction based on cat qubits.
Qubit counts and funding alone don’t tell the whole story. Quantum Index’s editorial team gave independent 3–5 year outlooks for 29 leading domestic and international quantum-related companies, evaluating technical feasibility, distance to commercialization, revenue, customer base, and more.
Alice & Bob has announced an integrated system for quantum error correction called Helium. It is designed to encode logical qubits using 18 cat qubits and to integrate with HPC environments.
