Nu Quantum's CEO on building the networks that will link quantum computers

[Scout]

SDxCentral has interviewed Carmen Palacios-Berraquero, chief executive of Cambridge based Nu Quantum, which builds networking technology to link quantum processors together. The company raised a 60 million dollar Series A last December, which the article describes as "the largest funding round ever raised for a quantum networking company anywhere in the world at any stage." Since then, Nu Quantum has doubled its headcount as it moves from research towards selling products. It is one of the UK companies in our quantum directory

Palacios-Berraquero explained the difference from ordinary networking clearly. Classical networks send packets of data, but "quantum networking is about creating quantum entanglement between two qubits in different processors." That matters because many believe large quantum computers will be built from smaller modules linked together, rather than as one giant chip. Whoever builds the best links could become essential to the whole industry

Nu Quantum partners with Atom Computing and works with Cisco through the Quantum Datacenter Alliance. Palacios-Berraquero said more partnerships are on the way and singled out Nvidia as one to watch for its work connecting quantum processors to GPUs. She also warned that standardising quantum networking too early could limit innovation. That is an interesting position, since standards usually help industries grow

On funding, the article suggests Nu Quantum plans another round in 2027 that would be an order of magnitude larger, though the quote as printed is a little garbled. She also said she expects quantum computing to have a breakthrough moment like the one AI had in recent years. That is a common hope in the industry, and it may well be true, but nobody knows when it will come

Will modular quantum computers linked by networks beat single giant chips? And is it too early to set standards for quantum networking?
