Cisco and Qunnect build quantum network using New York fiber optic cables

Core Viewpoint - Cisco Systems and Qunnect have successfully built and operated a quantum network using fiber optic cables in New York, demonstrating practical applications for quantum computing in real-world settings [1]. Group 1: Quantum Network Development - The quantum network connects Brooklyn and Manhattan, utilizing Qunnect's hardware and Cisco's software to address challenges in existing data centers [1]. - The network operates effectively over a distance of 17.6 kilometers (10.9 miles) of fiber optic cable, maintaining integrity through automatic polarization controllers [1]. Group 2: Technological Innovations - Qunnect's approach minimizes the need for cryogenic cooling, requiring it only at one central hub, while other connected data centers can operate with room-temperature equipment [1]. - The technology corrects for real-world issues that typically affect quantum networks, such as vibrations and complex fiber arrangements [1]. Group 3: Future Applications - Cisco envisions this foundational experiment as a step towards connecting quantum computers within data centers and eventually creating a quantum internet [1]. - Practical applications of quantum networks could include high-speed trading, where quantum entanglement allows for instantaneous information sharing between distant computers [1].
