IBM and Cisco are partnering to build the foundation for a large-scale, fault-tolerant quantum computing network, which could be realized as early as the 2030s.
The collaboration combines IBM’s progress in quantum processors with Cisco’s advances in quantum networking to link multiple quantum computers into a single distributed system capable of running massive computations.
Within five years, the companies plan to demonstrate a live proof-of-concept connecting multiple quantum machines, enabling them to share quantum information and work together across tens or even hundreds of thousands of qubits.
This breakthrough would enable researchers and industry to run workloads that are far too large for any single quantum computer today, including advanced materials design, complex medicine development, optimization systems, and climate or physics simulations.
The long-term goal is even more ambitious.
IBM and Cisco envision a future quantum computing internet that links quantum computers, sensors, and communication systems across cities, data centers, and eventually the globe.
This would unlock possibilities in ultra-secure communication, scientific modeling, and real-time sensing.
To get there, the companies will co-develop new hardware, optical-microwave transducers, a software stack for entanglement distribution, and a quantum networking unit that bridges quantum processors into the network.
Key Takeaways:
- IBM and Cisco plan to build a connected network of fault-tolerant quantum computers by the early 2030s.
- A first multi-computer demonstration is expected within five years.
- The partnership aims to lay the foundation for a future quantum computing internet.
