Entangled Networks

Entangled Networks, founded in 2021 by Aharon Brodutch and Ilia Khait, positioned itself as a critical enabler for the future of quantum computing. Brodutch, the former CEO, brought experience as a postdoctoral researcher at the University of Toronto and the University of Waterloo's Institute for Quantum Computing, while CTO Khait had a background as a postdoctoral researcher with a Ph.D. in Theory of Condensed Matter Physics. The Toronto-based company focused on solving the scalability problem that hinders the advancement of quantum computing.

The core of Entangled Networks' business was the development of technology to interconnect a massive number of quantum processor units (QPUs). This approach mirrors the multi-core architecture of classical supercomputers, where networking multiple processors together increases overall power. However, in the quantum realm, the network is used for computation itself, not just communication, by leveraging the phenomenon of entanglement across cores to form a single, much larger quantum computer. The company's business model involved providing optical hardware components, proprietary simulation software, and multi-QPU communication protocols. This suite of products and engineering support was designed to be integrated into other companies' existing hardware and software stacks, enabling customers like research institutions and corporations to build the interconnects needed for powerful quantum systems.

The company's product line included optical components like a light collection system and a network fabric switch, as well as software featuring an algorithm library, an optimizing controller, and real-time networking control. This technology addresses the challenge that quantum data cannot be cloned like classical data, requiring specialized hardware and algorithms to manage multi-core configurations. In January 2023, the company's trajectory took a significant turn when IonQ (NYSE: IONQ) acquired its operating assets. The deal led to the formation of IonQ Canada, with the Entangled Networks team joining the newly formed entity. This acquisition was a strategic move for IonQ to internalize the critical networking technology required for its roadmap of building modular, fault-tolerant quantum computers by linking multiple QPUs.
