Recent research into quantum computing development reveals a significant uptick in investment and practical applications, driven in part by government initiatives. Here's a summary of key findings from the State of Quantum 2024 report:
Government Investment and Accelerated Practical Applications
- Over 30 governments have committed to over $40bn in public funding for quantum technologies.
- National labs and quantum computing centers have accelerated practical applications, with dedicated centers and hubs emerging.
Transition from Lab to Market
- Startups are transitioning from lab research to market offerings.
- Full-stack deliveries of quantum computers are emerging in national labs and quantum centers.
Enterprise Interest and Investment Trends
- Enterprise interest in quantum technologies has doubled, but global private investment in the quantum industry declined by 50%.
- Investment in America declined significantly, while Europe, the Middle East, and Africa saw a 3% increase in quantum computing investment.
Adoption Challenges and Future Directions
- Current quantum computing systems face challenges meeting business needs.
- Transparency in quantum computing roadmaps is crucial for building confidence and managing expectations.
- Adoption barriers may evolve beyond fault tolerance and scalability to include challenges such as data security and cost per functional computation hour.
- Development of more primitives and practical algorithms is essential for exploring quantum computation beyond theoretical research.
Advancements in Error Correction
- Recent developments show improvements in error correction, paving the way for solving computationally challenging problems.
- QuEra Computing announced a roadmap for error-corrected quantum computers, with a 100-logical-qubit system planned for 2026.
- Alice & Bob unveiled a quantum error-correction architecture based on LDPC codes and "cat" qubits, promising significant improvements in error correction efficiency.
Cost and Adoption Considerations
- Cost remains a potential barrier to widespread adoption, as quantum computing time is expensive compared to other high-performance computing systems.
- Continued technological progress is expected, but challenges in estimating timelines for software improvements remain.
As the quantum computing landscape continues to evolve, addressing challenges in fault tolerance, scalability, and cost will be crucial for realizing the full potential of quantum technologies.
