Cisco Shows Switch that Can Connect Quantum Computers of Different Kinds
The prototype preserved quantum information with less than 4% degradation and is designed to link systems from different manufacturers without cryogenic cooling.
- On Thursday, April 23, 2026, Cisco Systems unveiled its Universal Quantum Switch prototype, enabling seamless connectivity between quantum systems from different vendors operating at room temperature over standard telecom fiber.
- Current quantum computers operate at hundreds of qubits with vendor-specific limitations, creating barriers to scalability. Cisco's switch addresses this by bridging differing encoding approaches to allow devices from different manufacturers to interoperate.
- Using a Cisco-patented conversion engine, the switch translates between major encoding modalities—Polarization, Time-Bin, Frequency-Bin, and Path—preserving quantum information with less than 4% degradation in proof-of-concept experiments.
- Vijoy Pandey, SVP of Outshift, Cisco's Emerging Technologies and Incubation Group, called the milestone a "pivotal moment," as Cisco collaborates with IBM, Qunnect, and Atom Computing on quantum development.
- Beyond the switch, Cisco's full-stack approach integrates the network-aware Quantum Compiler and applications, positioning the company alongside tech titans like Google in building a future quantum internet.
