We are pleased to announce that our portfolio company, Quantum Motion, has secured $160 million in Series C funding! 🚀 This achievement underscores the significant progress Quantum Motion is making toward advancing quantum computing and reflects growing conviction in their silicon transistor based architecture that offers to deliver utility scale quantum systems that are dramatically more efficient in space, cost and energy consumption than competing approaches. We first backed Quantum Motion in 2020, recognising the company’s unique promise and their ability to deliver silicon’s potential for scalable quantum computing. As a spin out from the University of Oxford and UCL, this is a massive win for the UK’s quantum sector, and makes Quantum Motion the UK’s best-funded quantum computing company. We are delighted to have worked with the British Business Bank in supporting their anchor investment in the round. 🤝 #NSSIF #Quantum #DeepTech #NationalSecurity #Innovation #UKTech #QuantumComputing
