Nu Quantum

A Cambridge company, spun out of the Cavendish Laboratory in 2018, building the networking technology that links quantum computers together.

About Nu Quantum

Nu Quantum works on a problem that sits between quantum computers: how to connect them. Today's quantum processors are small, and making one processor much bigger is very hard. Nu Quantum builds the networking layer that links many smaller processors so they behave like one large machine, which it calls the Entanglement Fabric. Its main product, the Qubit-Photon Interface, uses optical microcavities, tiny structures that trap light, to turn the quantum state of a qubit into particles of light that can travel along a fibre to another machine. The company says its approach is designed to work across different kinds of qubit.

The company was founded in 2018 by Dr Carmen Palacios-Berraquero, who is founder and chief executive, to commercialise about a decade of quantum photonics research from the Cavendish Laboratory at the University of Cambridge. The Cavendish head, Professor Mete Atature, is a founding adviser. In its own words the aim is networking technology that lets commercial quantum computers scale out. We did not find a published list of values, but its pages stress diversity and say it values people with different backgrounds, experiences and ideas.

Nu Quantum's research laboratories are in Cambridge. In February 2026 it opened a trapped-ion qubit networking laboratory near its existing research headquarters, which doubled its research space and which it calls the first dedicated industrial R&D facility for trapped-ion distributed quantum computing in the UK and Europe. It also has an office in Los Angeles. Collaborators named include the UK's National Quantum Computing Centre, the Universities of Sussex and Cambridge, Cisco, Infineon and Infleqtion.

The company page lists more than 60 staff across nine technical disciplines, and describes itself as multidisciplinary. The leadership team includes a vice president of technology, Dr Claire Le Gall, as well as leaders for product, engineering, legal and intellectual property, and business development, a chief financial officer and a director of people. These are the company's own descriptions.

Because the work spans physics, optics, electronics, software and systems engineering, a company like this can suit people from several backgrounds. Roles named in 2026 coverage include technical areas such as mechanical engineering, and the company said it was hiring in several technical areas. Its website has the up-to-date list.
