What’s next for quantum computing in Europe?
Quantum computing could solve problems beyond the reach of today’s computers and open new markets for the European industry. For Europe, the challenge is turning world-class research into industrial strength. Hitachi is contributing through decades of research and development in silicon quantum technology.
Professor Charles Smith, Head of Hitachi Cambridge Lab, Hitachi Europe, explains why quantum computing matters for Europe and how Hitachi is approaching the challenge of building quantum computers at scale.
Why does quantum computing matter for Europe’s industry?
The European Commission’s Quantum Europe Strategy aims to make Europe a global quantum leader by 2030. The question is how Europe turns R&D into industrial competitiveness.
Quantum computers will open new markets and solve problems that are not possible on a classical computer. For energy, rail and security sectors, that could mean new ways to balance grids, plan complex networks, and protect critical systems while opening up entirely new markets.
Why is scaling the biggest challenge for quantum computers?
Delivering value for society requires fault-tolerant quantum computers that can correct their own errors, which will need a large amount of qubits. Today’s systems are far smaller and adding qubits increases complexity and the risk of errors.
Why is Hitachi using silicon?
Silicon could offer a practical route to scale. Fault-tolerant quantum computers are expected to need around one million qubits, and silicon qubits can be made using the same kind of manufacturing processes the semiconductor industry already relies on. Hitachi is developing silicon quantum computers with this in mind, drawing on decades of semiconductor expertise. The Hitachi Cambridge Laboratory, established in 1989, is behind one of the first silicon qubit devices.
What’s next? How Hitachi is working to turn quantum computing into a competitive advantage for Europe
Hitachi’s goal is to build a fault-tolerant quantum computer that delivers tangible benefits to society. By combining long-term research at Hitachi Cambridge Laboratory with its semiconductor expertise and experience in rail, energy and security, Hitachi aims to help Europe turn quantum research into practical solutions for the sectors it depends on.
