The concept of the Quantum Node Economy proposes a future in which quantum computers are interconnected using secure quantum networks, similar to how the cloud currently allows disparate systems to communicate. Individual quantum nodes will not exist in silos, but rather will interoperate with artificial intelligence, high-performance computing, and the cloud in order to facilitate solutions for challenges across the health sciences, financial services, cybersecurity, logistics, energy, and the physical sciences.
Creating this type of ecosystem will necessitate three pillars. Infrastructure will be characterized by quantum processors, quantum networking and communication, cloud integration, and data security and transfer. Work force will require expertise in quantum computing, AI, cybersecurity, software development, photonics and systems engineering supported by institutions of higher education and industrial partnerships. Policy and governance will need to include standards and specifications for quantum technology, cyber security standards for quantum-safe communications, data protection, research and development incentives, international cooperation and ethical considerations for all of the aforementioned to spur development and protect national infrastructure.
The Quantum Node Economy is not meant to substitute classical computing, but to build upon it, uniting quantum computing, AI, and HPC as an intelligent, secure and an interconnected network to fuel future technological and economic advances.
