Cisco builds quantum stack: Universal Quantum Switch is missing link

"Cisco's Universal Quantum Switch is designed to interconnect quantum computers, enabling multiple smaller systems to function as a larger quantum computer. This is essential for scaling quantum computing capabilities."

"The current focus on increasing the number of qubits in quantum systems is insufficient; practical applications will require hundreds of thousands or even millions of qubits, highlighting the need for interconnectivity."

"Creating a quantum network involves significant challenges, as different technologies like Neutral-Atom, Trapped Ion, Photonic, and Superconducting require unique approaches, complicating the standardization of quantum computing."

"The Universal Quantum Switch will facilitate the movement of entangled photon pairs, which is crucial for the effective operation of a quantum network, marking a significant advancement in quantum technology."

Cisco is advancing quantum computing by developing a Universal Quantum Switch, which aims to interconnect quantum computers. Current systems have over 5,000 qubits, but achieving practical applications will require hundreds of thousands or millions of qubits. The Universal Quantum Switch is a crucial step in creating a quantum network, following the Quantum Network Entanglement Chip. Connecting quantum computers presents significant challenges due to the diverse technologies used, including Neutral-Atom, Trapped Ion, Photonic, and Superconducting methods, which complicate standardization efforts.
