Cisco

Cisco Systems Inc. is a San Jose-based technology company founded in 1984, developing quantum networking technology and quantum internet infrastructure through Cisco Quantum Labs established in Santa Monica and San Jose facilities. In May 2025, Cisco formally opened its Quantum Labs facility in Santa Monica, unveiling industry-first quantum technologies including network-aware distributed quantum compiler enabling quantum algorithms across multiple networked processors, vendor-agnostic quantum networking framework, and prototype quantum entanglement chip developed with UC Santa Barbara generating one million entangled photon pairs per second at room temperature. Cisco's quantum networking vision accelerates practical quantum computing applications from decades to 5-10 years, creating foundation for quantum internet. Cisco announced industry-first compiler supporting distributed quantum error correction, working with any quantum computing technology to enable scalable quantum data centers and quantum communication networks worldwide. In September 2025, Cisco expanded its quantum networking software portfolio with enhanced network orchestration capabilities for quantum key distribution (QKD) networks, enabling enterprise-grade quantum-safe communications infrastructure and integration with existing network management systems for hybrid classical-quantum network deployments.

2025 Developments: Cisco partnered with Nu Quantum and others in Quantum Datacenter Alliance (March 2025).
