QphoX develops core quantum internet hardware focused on quantum transduction, translating quantum information between microwave and optical domains. The company demonstrated optical-frequency readout of superconducting qubits in October 2023 as a proof of concept. Management says its transduction hardware is at a performance level that will allow quantum systems to connect through optical quantum channels. The €8 million investment — the largest in a Dutch quantum company to date — will be used to commercialise and bring QphoX's quantum modem technology to market. The raise underscores the firm's position in the quantum networking space and provides capital to move from demonstration to productisation. QphoX is developing a commercial "quantum modem" that coherently converts electrical and microwave signals to optical signals and back so separate quantum processors can communicate. The company’s modem is designed to be agnostic to qubit type, focusing on the microwave-to-optical interface to work with superconducting and topological qubits. QphoX aims to enable networking of separate processors so quantum computers can scale beyond tens or hundreds of qubits. The modem originated at TU Delft and the company is building that academic prototype into a real product. Simon Gröblacher is CEO and co-founder. QphoX recently raised €2 million to advance product development and commercialization.
