- New collaboration plans to unite strengths of both leaders to design a connected network of large-scale, fault-tolerant quantum computers, targeted by early 2030s
- Companies plan to deliver an initial demonstration of multiple networked quantum computers within five years
- Distributed quantum network could lay groundwork towards quantum computing internet defined by quantum computers, sensors, and communication in the late 2030s
YORKTOWN HEIGHTS, N.Y. and SAN JOSE, Calif., Nov. 20, 2025 /PRNewswire/ -- Today, IBM (NYSE: IBM) and Cisco (NASDAQ: CSCO) announced an intention to collaborate on the groundwork for networked distributed quantum computing, to be realized as soon as the early 2030s. By combining IBM's leadership in building useful quantum computers with Cisco's quantum networking innovations, the companies plan to explore how to scale large-scale, fault-tolerant quantum computers beyond IBM's ambitious roadmap. Additionally, they will work to solve fundamental challenges towards a quantum computing internet.
Within five years, IBM and Cisco will aim to demonstrate the first proof-of-concept for a network that combines individual, large-scale, fault-tolerant quantum computers, enabling them to work together to run computations over tens to hundreds of thousands of qubits. This network would allow problems to be run with potentially trillions of quantum gates, the fundamental entangling operations required for transformative quantum applications such as massive optimization problems, or the design of complex materials and medicines.
"At IBM, our roadmap includes plans to deliver large-scale, fault-tolerant quantum computers before the end of the decade," said Jay Gambetta, Director of IBM Research and IBM Fellow. "By working with Cisco to explore how to link multiple quantum computers like these together into a distributed network, we will pursue how to further scale quantum's computational power. And as we build the future of compute, our vision will push the frontiers of what quantum computers can do within a larger high-performance computing architecture."
"Getting quantum computing to useful scale is not just about building bigger individual machines, it is also about connecting them together," said Vijoy Pandey, GM/SVP at Outshift by Cisco. "IBM is building quantum computers with aggressive roadmaps for scale-up, and we are bringing quantum networking that enables scale-out. Together, we are solving this as a complete system problem, including the hardware to connect quantum computers, the software to run computations across them, and the networking intelligence that makes them work."
Scaling a Distributed Quantum Computing Network
IBM and Cisco intend to explore the development of quantum hardware and software that could physically link many large-scale, fault-tolerant quantum computers together to form networked distributed quantum computing.
The companies are targeting an initial proof-of-concept demonstration by the end of 2030, for which they plan to entangle qubits from multiple separate quantum computers located in distinct cryogenic environments. Doing so will require the companies to invent new connections, including microwave-optical transducers and a supporting software stack.
The Cisco vision for a quantum data center introduces an architecture for quantum networking infrastructure that could make distributed quantum computing a reality in the near future. This vision includes a complete hardware and software stack that aims to preserve fragile quantum states, distribute entanglement resources, facilitate teleportation between quantum computers, and synchronize operations with sub-nanosecond precision.
To scale beyond linking two quantum computers that are separate but physically close, IBM and Cisco are planning to explore how to transmit qubits over longer distances, such as between buildings or data centers. To achieve this, the companies will explore optical-photon and microwave-optical transducer technologies, as well as investigate how they can be incorporated into a quantum network to transfer quantum information as needed.
Linking together multiple quantum computers will require an appropriate interface. IBM plans to build a quantum networking unit (QNU) to serve as the interface to a quantum processing unit (QPU), with the explicit task of taking stationary quantum information in the QPU and converting it into "flying" quantum information through the QNU to then be further linked across potentially multiple quantum computers through a network.
Cisco's quantum network would aim to distribute the entanglements to arbitrary pairs of these QNUs on an on-demand basis to drive the quantum information transfer required for a given quantum algorithm or application. Towards this goal, Cisco is developing a high-speed software protocol framework that can continuously and dynamically reconfigure network paths so entanglements could be distributed to the QNUs when they are done with their partial computations.
Together, the companies plan to investigate how a network bridge, comprised of novel hardware and open-source software, could use Cisco quantum network nodes to link many IBM QPUs within a data center through its QNU interface. In the future, this approach could be extended to link QPUs across multiple data centers. This would scale a larger quantum network across even larger distances to form the groundwork for a future quantum computing internet.
IBM quantum computers linked by this architecture could facilitate massively computationally demanding workloads, including those that require high-performance computing resources as part of a quantum-centric supercomputing framework.
Towards this vision, IBM is also working with the Superconducting Quantum Materials and Systems Center (SQMS), led by Fermi National Accelerator Laboratory, in its role as a member of four of the U.S. Department of Energy National Quantum Information Science and Research Centers. Together, IBM and SQMS intend to investigate how many QNUs could be used within quantum data centers, and they are planning an initial demonstration of multiple connected QPUs within the next three years.
The Foundation of a Quantum Computing Internet
Building a distributed and scalable quantum computing network will create a pathway towards an exponentially large computational space and enable the expansion of diverse technologies, which could begin to form a future quantum computing internet by the late 2030s.
A quantum computing internet provides a future where many distributed quantum-based technologies, such as quantum computers, quantum sensors, and quantum communications are connected and share information across distances, such as a metro region and eventually, at a planetary scale. This bold vision could facilitate new possibilities such as ultra-secure communications, or precise monitoring of climate, weather, and seismic activity.
As another part of their current intention to collaborate, IBM and Cisco plan to co-fund academic research and collaborative projects to advance the broader quantum ecosystem, following a long history of fostering research in academic and national labs.
