# Quantum Machines

> Quantum Machines supplies quantum control hardware and software to quantum computer builders, research laboratories and HPC centers. Its OPX controllers, Pulse Processing Unit and QUA programming language coordinate qubit operations with real-time classical processing; QUAlibrate automates calibration, and its Open Acceleration Stack connects external accelerators to the control loop.

- **Founded:** 2018
- **Headquarters:** Tel Aviv, Israel
- **Founders:** Itamar Sivan (Co-founder and CEO), Yonatan Cohen (Co-founder and CTO), Nissim Ofek (Co-founder and Chief Engineer)
- **Products:** OPX1000, OPX+, Pulse Processing Unit (PPU), QUA, QUAlibrate
- **Notable:** Reported 99.5% median two-qubit gate fidelity across 11 functioning pairs on a nine-qubit Rigetti Novera QPU in May 2026, after seven working days of bring-up., Launched OPX1000 in August 2023., Raised $170 million Series C in February 2025.

## Products & services

- **OPX1000** — Modular hybrid quantum control platform with microwave and low-frequency front-end modules, real-time classical processing and synchronized operation across units.
- **OPX+** — Integrated quantum control and readout controller with real-time processing and feedback.
- **Pulse Processing Unit (PPU)** — Processor architecture combining pulse generation, measurement handling, classical calculations and control flow.
- **QUA** — Pulse-level programming language combining quantum operations and real-time classical logic, with Python-based development tooling.
- **QUAlibrate** — User-programmable calibration framework with nodes, graphs and a web interface. Launched as open source in 2025; the current repository says it remains free to use but source code has moved private.
- **Open Acceleration Stack** — Framework connecting classical CPUs, GPUs, FPGAs and ASICs to quantum control through low-latency interfaces including OPNIC and NVIDIA NVQLink.
- **Octave** — RF up/down conversion product for quantum control, with frequencies up to 18 GHz.
- **QDAC-II and QDAC-II Compact** — Low-noise multi-channel voltage generators for quantum-device control.
- **Cryogenic electronics** — QBoard II sample holders, QFilter II low-pass filters and related packaging and interconnection products from the QDevil division.
- **Integration and application support** — Technical scoping, demonstrations, customer support and assistance integrating quantum control into research and computing systems.
