  • Within five years, IBM and Cisco will aim to demonstrate the first proof-of-concept for a network combining individual, large-scale, fault-tolerant quantum computers, the companies said.
  • The companies added that this network would allow problems to be run with potentially trillions of quantum gates.
  • IBM and Cisco said they intend to explore developing quantum hardware and software that could physically link many large-scale, fault-tolerant quantum computers.

International Business Machines (IBM) and Cisco Systems (CSCO) announced a collaboration on the groundwork for networked distributed quantum computing on Thursday, with plans to realize it by the early 2030s.

The companies stated that they plan to explore scaling large-scale, fault-tolerant quantum computers and are working to address 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 combining individual, large-scale, fault-tolerant quantum computers, enabling them to work together to run computations over tens to hundreds of thousands of qubits. 

The companies said that this network would allow problems to be run with potentially trillions of quantum gates.

Executive View

"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,” said Jay Gambetta, Director of IBM Research and IBM Fellow.

“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,” he added.

Scaling Distributed Quantum Computing Network

IBM and Cisco said they intend to explore the development of quantum hardware and software that could physically link many large-scale, fault-tolerant quantum computers to form a networked, distributed quantum computing system.

What Is Retail Thinking?

Retail sentiment on IBM remained unchanged in the ‘bearish’ territory, while Cisco’s sentiment dropped to ‘bearish’ from ‘extremely bullish’ territory compared to a day ago.

Shares of IBM have gained 31% this year, and Cisco stock has jumped over 32% in the same period.
