Cisco has launched its Quantum Labs in Santa Monica, revealing a prototype quantum network entanglement chip developed with the University of California, Santa Barbara. This chip allows for the generation of entangled photon pairs that transmit quantum states through quantum teleportation, a process famously noted by Albert Einstein. Cisco emphasizes that its architecture for quantum datacentres differs significantly from classical systems, requiring specialized hardware, entanglement management, and precision synchronization to maintain fragile quantum states across networks, paving the way for future computing innovations.
Integrated photonics enables many sources to be combined onto a single chip, and by packaging these sources with optical fibre and electronic controls, a single device can boost the entanglement rates for many users on their quantum network.
The challenges for quantum datacentre network fabric are fundamentally different from classical ones. Quantum datacentres must preserve fragile quantum states, distribute entanglement resources, facilitate teleportation between processors and synchronise operations with sub-nanosecond precision.
