# Alice & Bob 2030 Roadmap to Useful Quantum Computers. **We placed our bet on cat qubits**, an emerging technology at the time, but one that promised to provide the strong foundation needed for practical, fault-tolerant quantum computing in a more efficient way. **A single, well-controlled cat qubit is a strong building block** for fault-tolerant quantum computers that are both powerful and efficient. This roadmap provides a detailed, technical view of which cat qubit-based quantum processing units, the successors to our Boson chips, awaits us along the way. In this short blog post, I have mentioned several key concepts of quantum computing: **qubits, quantum error correction, universality…** However, for accurately understanding our strategy and, more broadly, for appreciating the real challenges facing the field, **getting familiar with these concepts is essential**. By focusing on hardware efficiency with cat qubits, we are **reducing the resources needed to achieve quantum advantage** and enhancing the impact of every new, scaled-up solution the superconducting qubit community delivers.

“We are the only company with a clear and demonstrable path that leverages quantum computing to tackle large-scale scientific and commercial applications,” said **Dr. Rajeeb Hazra, CEO of Quantinuum**. **March 11, 2026 – Singapore –** Quantinuum, a leading quantum computing company, today announced the establishment of a new R&D and Operations Centre (the “Centre”) in Singapore, marking its formal expansion into Singapore. This important development will enable Quantinuum to deepen collaboration with the nation’s research and industrial ecosystem, together with the company’s plan to deploy its Helios quantum computer in Singapore later this year. * **Dr.** **Marvin Lee, Country Leader for Quantinuum Singapore**, who recently joined the company following senior appointments at A\*STAR, EDB, and NRF, where he played a key role in shaping the National Quantum Strategy, said: “The new Centre will enable local talent and industry to work hands-on with quantum technologies, co-develop solutions aligned with national priorities, and support high-value jobs.
Our approach is structured according to technology “families” among companies with deliverable products or services – think the **superconducting qubits** we’ve come to associate with [IBM](https://www.tomshardware.com/tag/ibm), [Google](https://www.tomshardware.com/tag/google), and Rigetti; **trapped-ions** (which have seen the most solid bets from IonQ and Quantinuum); **quantum annealing** and its particular track-record in optimization problems (D-Wave); **neutral atom tech** (Atom Computing, QuEra); and **photonics** (Xanadu, PsiQuantum). Google’s current hardware revision for quantum processors is [Willow](https://blog.google/technology/research/google-willow-quantum-chip/) – a 105-qubit superconducting-qubit chip that [the company claimed](https://www.tomshardware.com/tech-industry/quantum-computing/googles-quantum-echo-algorithm-shows-worlds-first-practical-application-of-quantum-computing-willow-105-qubit-chip-runs-algorithm-13-000x-faster-than-a-supercomputer) showcases quantum advantage (in this case, being able to perform calculations that are deemed impossible for classical computers to solve within even the lifetime of our observable universe). Much like IBM, Google understands that qubit quality, coherence and interconnectivity are as important (if not more important) than raw qubit counts; while Willow was introduced in 2024, the company’s latest announcement in the area pertains not to a hardware revision but to improved error-correction algorithms, with their “[Quantum Echoes](https://www.tomshardware.com/tech-industry/quantum-computing/googles-quantum-echo-algorithm-shows-worlds-first-practical-application-of-quantum-computing-willow-105-qubit-chip-runs-algorithm-13-000x-faster-than-a-supercomputer)” allowing for verifiable, cross-benchmarkable, repeatable quantum computing results.
