- The development of a quantum internet will require the creation of new technologies and expertise from universities and federal labs.
What happened: IBM and Cisco plan quantum computer connection
IBM and Cisco have announced plans to connect quantum computers across long distances, with the ambitious goal of demonstrating the concept by the end of 2030. The collaboration aims to lay the groundwork for a quantum internet, a network that could revolutionise industries by enabling quantum computers to work together in real time. This is part of a broader effort to solve complex problems in fields such as physics, chemistry, and cybersecurity that existing computers would take millennia to address.
The quantum computers at the heart of this initiative, including IBM’s advanced machines, are housed in ultra-cold environments that inhibit communication. IBM is focusing on developing technology to transform information from stationary quantum bits (qubits) into ‘flying’ qubits capable of moving through microwaves. These qubits will then be converted into optical signals for transmission over fibre-optic cables.
The effort will require advancements in technology that do not yet exist, such as the microwave-optical transducer. This new device, which converts microwave signals into optical ones, will be developed in partnership with leading research centres like the Superconducting Quantum Materials and Systems Center, operated by the Fermi National Accelerator Laboratory.

Why it’s important
The development of a quantum internet would mark a major leap in computing power, allowing quantum machines to share data across vast distances. Quantum computers are expected to be far more powerful than today’s machines, able to solve problems that are currently beyond reach. However, reliable, large-scale quantum machines remain a challenge due to their error-prone nature.
Both IBM and Cisco are emphasising the collaborative approach to this venture. The companies believe that by working together and with external research groups, they will increase the chances of success. Open-source software will be shared along the way to help integrate the complex components of the quantum network.
The quantum internet could have transformative impacts on various industries, including drug discovery, financial modelling, and encrypted communications. However, achieving this vision will require solving fundamental technical challenges over the next decade.
