Electronic Design opinion piece from Charles Foley, chairman and CEO of quantum networking company memQ, arguing that networking is the missing piece in scaling up quantum computers. Foley has spent more than 40 years in tech leadership, including time at IBM and NetApp. His main point is that the industry should stop waiting for single giant quantum computers and start connecting smaller ones together

He draws a comparison with supercomputing. In the 1980s and 1990s, the biggest machines were single monolithic systems, but the industry later moved to clusters of many smaller computers linked together. Foley thinks quantum computing will follow the same path. Instead of trying to build one machine with millions of qubits, you network many smaller processors

The catch is that quantum networks are much harder than classical ones. You need infrastructure that can keep delicate quantum states intact and extend them between connected systems. Improving the distance over which that works is one of the key technical challenges. He also points to US initiatives like DARPA's HARQ project and a recent executive order as signs that policymakers see networking as essential, not an afterthought

He mentions that around $4 billion was invested in quantum computing in the past year, and that commercial deployment is not expected until the next decade. The industries he highlights as likely winners are pharmaceuticals, financial services and materials science. None of that is surprising, but it is useful context

Obviously the CEO of a quantum networking company is going to argue that quantum networking is essential, so take it with a pinch of salt. That said, the logic of distributed computing is hard to argue with, and several big players are working on linking processors already. Do you think networked quantum computers are the way forward, or will monolithic machines win out?
