Spun out of TU Delft, in early 2026 it launched a quantum transducer converting the microwave signals of superconducting qubits into telecom optical photons, with IBM as its first test partner.
2026Fault line
Microwave-to-optical quantum transduction is still a very young technology, with low conversion efficiency and unproven at scale. The company is small and depends on funding and large partners.
