The Race to the Quantum Internet: IBM and Cisco Reveal Ambitious Network Blueprint

In today’s Cloud Wars Minute, I look at how IBM and Cisco are teaming up to pioneer long-distance quantum networks.

Highlights

00:03 — Although not the only company invested in the development of quantum computing, IBM is certainly considered the most active. The company has the highest number of patents, a clear road map for fault tolerant quantum systems, and the most prestigious track record across quantum hardware, software and the commercialization of these tools.

00:28 — Now, IBM and Cisco Systems have revealed plans to link a network of quantum computers over long distances — and the result, perhaps the introduction of the quantum internet. Before I get carried away on this, leaders from both IBM and Cisco have confirmed that the technology to power these networks doesn't yet exist, but they are working on it.

00:59 — The bottleneck is getting qubits, the unit of information used by quantum computers, to travel along fiber optic cables between Cisco switches. IBM and Cisco hope to have the first proof-of-concept ready within five years, a network that connects individual, large scale, fault-tolerant quantum computers with the power to run computations over 10s to hundreds of 1000s of qubits.

01:49 — So, why do we need the quantum internet? Well, beyond the massive enhancement in computational power, which is the primary driver for companies to enter this space, if quantum computing itself becomes widespread, we'll need quantum structures in the Internet to protect ourselves from our very own creation.

02:28 — Technology is advancing at an unfathomable speed, and just like in the AI space, we need to ensure it's contained. In fact, researchers at IBM co-developed three of the four quantum resistant algorithms that the U.S. National Institute of Standards and Technology, or NIST, have earmarked for future standardization.
