Focus areas
Roles in the quantum ecosystem
- Computing hardware
- Companies building quantum processors and complete computing systems.
- Software & applications
- Tools for programming quantum computers, developing algorithms, and exploring applications.
- Control & infrastructure
- The electronics and software that operate, calibrate, and read out quantum devices.
- Communication & security
- Quantum networks, quantum key distribution, and quantum randomness. Post-quantum cryptography is a distinct, classical approach; a security offering alone does not imply a quantum computer.
Descriptions summarize the cited companies’ stated activities, not independent performance verification. This first edition focuses on specialist companies and is not a complete list of corporate quantum programmes.
