Cisco and IBM will collaborate to create a connected network of large-scale, fault-tolerant quantum computers with a target of 2030 for proof-of-concept.
IBM and Cisco say a distributed quantum network would lay the groundwork towards a quantum computing internet defined by quantum computers, sensors and communications in the late 2030s.
The companies say that combining IBM’s experience in building useful quantum computers with Cisco’s quantum networking innovations will allow them to explore how to solve fundamental challenges towards a quantum computing internet. They hope to demonstrate a first proof-of concept within the next five years.
The aim is to ultimately create a network of large-scale, fault-tolerant quantum computers, enabling them to work together “to run computations over tens to hundreds of thousands of qubits”.
They say such a network would potentially allow problems to be run with trillions of quantum gates, “the…
