Quantum Machines
Quantum-control hardware and software vendor. Ships the OPX family of pulse-level controllers (OPX, OPX+, OPX1000) and the QUA programming language used to drive superconducting, trapped-ion, neutral-atom, and spin qubits; the installed base spans more than half of the organisations building quantum computers worldwide. Co-developed NVIDIA DGX Quantum (OPX1000 + Grace Hopper, sub-4 us round-trip) as a GPU-coupled quantum-control reference platform. Founded in Tel Aviv in 2018 by Weizmann Institute alumni Itamar Sivan, Yonatan Cohen, and Nissim Ofek; closed a USD 170M Series C in February 2025 led by PSG Equity, taking cumulative funding to USD 280M.
