Delft, The Netherlands, 30 September 2025 -- QuantWare, the highest-volume supplier of quantum processing units (QPUs) worldwide, has today announced the delivery of its 64-qubit Tenor QPU to the University of Naples Federico II (Unina), powering Italy's largest quantum computer. The Tenor now operating at the University of Naples is the first in a broader rollout by QuantWare to its early-access partners.

The Tenor-powered quantum computer at the University of Naples (Unina) is a product of the Quantum Open Architecture (QOA) model, which significantly lowers the time and capital required to build world-class systems. Just a few years ago, before QOA players like QuantWare entered the market, any organization seeking a quantum computer had to either buy a closed system from a full-stack provider or build one from scratch. Both options were too time and capital intensive for most organisations to become widely adopted. The Quantum Open Architecture is changing that, and this quantum computer at the University of Naples is a great example of how the QOA model is putting world-class quantum computers in the hands of a much wider ecosystem.

“Building Italy's largest quantum computer required a processor that was not only powerful, but commercially available and ready for integration.” said Prof Francesco Tafuri, head of Quantum Computing Napoli (QCN) Laboratory at the Department of Physics “Ettore Pancini" of the University of Napoli “Federico II”. “QuantWare's Tenor QPU significantly accelerated our timeline and allowed us to focus on building the system and its applications”.

"Our goal is to empower the entire ecosystem," said Matt Rijlaarsdam, CEO of QuantWare. "Through the Quantum Open Architecture, we empower the whole ecosystem to innovate and build upon our processors. This milestone shows the effectiveness of that approach: the University of Naples is now operating a quantum computer that is beyond most of the systems built by closed architecture players.”
