International Business Machines Corporation (NYSE:IBM) and Cisco Systems, Inc. (NASDAQ:CSCO) on Thursday disclosed plans to collaborate on building the foundation for networked distributed quantum computing.
Details
The partnership combines IBM’s expertise in practical quantum computers with Cisco’s innovations in quantum networking.
The companies aim to scale large, fault-tolerant quantum systems beyond IBM’s current roadmap and tackle key challenges toward creating a quantum computing internet.
IBM and Cisco are targeting realization by the early 2030s. Within five years, the companies plan to showcase a proof-of-concept network linking large-scale, fault-tolerant quantum computers, enabling joint computations across tens to hundreds of thousands of qubits.
Notably, this network could execute trillions of quantum gates, supporting…
