“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,” the companies stated. “To achieve this, the companies will explore optical-photon and microwave-optical transducer technologies and investigate how they can be incorporated into a quantum network to transfer quantum information as needed.”
Cisco’s quantum network would aim to distribute the entanglements to arbitrary pairs of QNUs on an on-demand basis to drive the quantum information transfer required for a given quantum algorithm or application, the vendors said. “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.”
Big Blue and Cisco said they plan to…
