This is a 3x increase from 2023, and 76% of those investing in 2024 gained value to a large or very large extent. Such an increment supports the business case for engaging quantum startups now, especially where quantum-inspired approaches improve decision quality, speed experimentation, or reduce risk in complex systems. Moreover, the UK government states that its National Quantum Strategy commits GBP 2.5 billion over 10 years from 2024 to develop quantum technologies. It is expected to generate an additional GBP 1 billion of private investment into the programme. This indicates a structured national push toward deployable quantum capabilities. Consequently, startups are working to operationalize these deployable quantum capabilities across computing, sensing, communications, and cybersecurity applications.
