Quantum Motion Raises $160 Million to Scale Silicon-Based Quantum Computers

Overview

• Quantum Motion closed a $160 million Series C co-led by DCVC and Kembara, with the British Business Bank, Firgun and existing backers joining.
• The company says the funding will speed work on silicon transistor qubits built to run in standard data center racks.
• According to the company, its CMOS route could cut cost and footprint by about 100 times and power use by about 1,000 times versus rival designs.
• Its chips are made on GlobalFoundries lines and use the spin of a single electron in a tweaked transistor to act as a qubit.
• Quantum Motion cites a 2025 system at the UK National Quantum Computing Centre and progress to Stage B in DARPA’s benchmarking effort as proof points.
