SEPTEMBER 3, 2026 LONDON, UK — Quantum Motion, the leader in silicon spin-based quantum computing, today announced the second close of its series C funding round to accelerate the scale-up of its fault-tolerant quantum hardware.

This second close of the series C round led by DCVC and Kembara contributes investments from Imec.ventures, Lansdowne Partners, Sony Innovation Fund, S3 Ventures, and Inkef. The funding will drive custom silicon co-development, leverage global semiconductor manufacturing pipelines and build upon key milestones including international expansion, notably opening US lab in Maryland, and participation in stage B of DARPA’s Quantum Benchmarking Initiative (QBI).

Quantum Motion is deliberately focused on industrial scalability. While many alternative quantum computing architectures carry a price tag upwards of $100 million per machine, because of the need for bespoke specialised hardware, Quantum Motion’s silicon transistor-based approach using the standard silicon CMOS fabrication technology used in everyday chip manufacturing enables a 100-fold reduction in cost to single digit millions. Its systems are designed to be deployed into standard data-centre environments and racks, with a 100-fold reduction in space and 1000-fold reduction in energy consumption compared to alternatives.

“Silicon technology transformed classical computing and it remains the only platform capable of delivering the density and scale required for practical quantum utility,” said James Palles-Dimmock, CEO of Quantum Motion. “This commitment from major strategic and financial investors validates our engineering-first strategy and will accelerate our progress towards a utility scale quantum computer. By tapping into existing global semiconductor supply chains, we are bypassing the cost bottlenecks of bespoke manufacturing and bringing commercially viable quantum systems to market faster.”
