Cisco Blogs reports that their Quantum Labs has introduced software designed to network quantum computers together, enabling breakthroughs in both quantum and classical applications. According them, today’s quantum systems remain stuck at the scale of hundreds of qubits, far from the millions required for real-world use. Rather than wait decades for perfect processors, the company is pushing forward by networking existing machines.
The announcement includes three research prototypes:
- Quantum Compiler – the first network-aware, distributed compiler that allows algorithms to run across multiple processors. It also introduces distributed quantum error correction.
- Quantum Alert – a demonstration application providing eavesdropper-proof security backed by physics rather than classical software promises.
- Quantum Sync – an application that uses entanglement for coordinated decision-making across distributed locations, extending benefits to classical use cases such as finance.
All three prototypes operate within a unified quantum networking software stack. The security company states this infrastructure makes it possible for quantum systems to work together instead of remaining isolated.
Building the Full Quantum Networking Stack
Cisco emphasizes a systems-level, full-stack philosophy, similar to the one that shaped the classical internet. This approach includes developing a quantum networking chip, control software with defined APIs, and applications for both classical and quantum workloads.
Following its recent unveiling of a chip generating over 200 million entangled photon pairs per second, they now adds software that turns entanglement into practical networking capabilities.
The unified stack is built on three layers:
- Applications – such as the distributed quantum compiler now released for experimentation.
- Control layer – hosting protocols and algorithms to manage devices and applications across the quantum network.
- Devices layer – providing SDKs and APIs for real and simulated devices.
Cisco’s Quantum Compiler Prototype
One highlight is the Quantum Compiler, engineered for distributed quantum computing across multiple processors in a quantum data center. By partitioning circuits and managing entanglement scheduling, the compiler enables scalable execution across heterogeneous systems.
Unlike existing compilers limited to single machines, Cisco’s version supports quantum interconnect requirements and distributed error correction. This is positioned as a critical step for industries such as pharmaceuticals, finance, and research institutions, where algorithms are too complex for single nodes.
Extending to Classical Use Cases
Cisco also highlights Quantum Alert and Quantum Sync as demonstrations of classical benefits. Quantum Alert uses entanglement to detect eavesdropping attempts, complementing encryption standards like PQC and guarding against harvest-now-decrypt-later threats. Quantum Sync coordinates distributed decisions without direct message exchanges, valuable in high-frequency trading where milliseconds matter.
From Research to Demonstration
Together with Outshift by Cisco, the Quantum Labs team has built a complete software prototype capable of controlling, monitoring, and managing entanglement-based quantum networks across diverse computing platforms, including superconducting, ion-trapped, and photonic systems.
Cisco plans to showcase these advances live at its upcoming Quantum Summit, where the Quantum Compiler prototype will also be available for download.
