IBM and Cisco said they will build a connected network of quantum computers that will look to scale to hundreds of thousands of qubits.
The companies plan to demonstrate multiple networked quantum computers within five years.
Both companies have quantum computing plans first in hybrid quantum-HPC systems and then quantum. IBM’s quantum efforts are well known and Cisco has been revving quantum networking efforts.
IBM and Cisco, two classical computing giants, are battling pure play quantum companies that are also investing heavily in networking systems together. For instance, IonQ has acquired multiple startups focused on quantum networking.

Key points:
- IBM and Cisco plan to design a network of large-scale fault tolerant quantum systems by the early 2030s.
- The companies will demonstrate network quantum systems within five years.
- The quantum network will serve as the base for quantum internet, communications and…
