What Quantum Machines Does
Quantum Machines (QM) is a Tel Aviv–based company founded in 2018 that builds the “control layer” for quantum computers the hardware and software that tells fragile qubits what to do, when, and how to talk to classical computers in real time.
Think of it this way: if qubits are the “engine” of a quantum computer, QM builds the ECU, transmission, dashboard, and telemetry stack that lets researchers and companies actually drive it.
Their flagship product is the Quantum Orchestration Platform (QOP) a unified stack combining:
Hardware controllers (OPX+, OPX1000, Octave, QDAC, QSwitch, QBox) that generate and read microwave/optical pulses with sub‑microsecond latency.
Software stack including the QUA pulse-level language, QUAlibrate for automated calibration, Qolab for experiment management, and integrations with NVIDIA DGX Quantum and NVQLink for hybrid quantum–classical workflows.
QM’s systems support multiple qubit modalities (superconducting, trapped-ion, neutral-atom, spin, photonics), which is why they’re used inside labs and companies building very different kinds of quantum hardware.
Why This Matters for Investors
Quantum Machines sits in the “picks and shovels” layer of the quantum value chain:
They don’t bet on one qubit technology winning; they enable almost all of them.
As qubit counts rise and error correction becomes mandatory, the need for fast, scalable, automated control grows faster than the number of qubits.
QM claims its technology is used by more than half of the companies building quantum computers worldwide, including quietly inside major programs like Google’s Willow.
That makes QM a infrastructure play with potential ARM-like dynamics in the quantum era: if quantum computing scales, their control stack becomes ubiquitous.
Funding, Valuation Signals & Investor Base
Total Raised & Rounds
Reported totals vary slightly by source, but the consistent picture is:
Total funding: ~$264M–$280M across 4–5 rounds.
Latest round: $170M Series C in February 2025.
Earlier rounds include Seed ($5.5–$6M), Series A (~$18M), Series B (~$50M), and a Series B+ (~$20M).
Lead & Notable Investors
Key investors include:
PSG (PSG Equity) – lead on Series C.
Intel Capital – strategic investor, aligning with QM’s role in quantum hardware ecosystems.
Battery Ventures, TLV Partners, Red Dot Capital Partners, Glilot Capital Partners, Citi Ventures, Energy Impact Partners, Qualcomm Ventures – long-term backers across multiple rounds.
Qualcomm Ventures joined via a Series B extension, highlighting 5G/edge and RF control synergies.
This investor mix signals:
Strong strategic corporate interest (Intel, Qualcomm, Citi).
Deep Israel/quantum-specialist VC support (TLV, Glilot, Red Dot, Battery).
While an exact post‑money valuation isn’t publicly disclosed in the sources reviewed, a $170M Series C in a capital‑intensive, pre‑revenue-heavy sector typically implies a high‑hundreds-of-millions to low‑billions USD private valuation range, depending on revenue traction and strategic terms.
Core Technology Stack
1. Quantum Orchestration Platform (QOP)
QOP is QM’s full-stack control system:
Hardware: OPX+ and OPX1000 controllers with custom Pulse Processing Unit (PPU) architecture for real-time feedback, arbitrary waveform generation, and sub‑microsecond classical–quantum round trips.
Latency specs: Active reset latency around 160 ns, and classical–quantum integration under 4 µs in newer open acceleration stacks.
Scalability: A single OPX1000 rack can control multiple stations and qubit modalities simultaneously (e.g., 5 different stations in one demo).
2. Software & Automation
QUA: Pulse-level programming language that lets researchers define complex experiments compactly.
QUAlibrate: Automated calibration tools that can calibrate multi‑qubit chips in seconds (e.g., 20‑qubit chip in under 60 seconds in a 2026 demo).
Qolab: Experiment and data management platform for running, tracking, and reproducing quantum experiments.
Hybrid integration: Tight coupling with NVIDIA DGX Quantum and NVQLink for real-time GPU–quantum orchestration, crucial for error correction and large-scale algorithms.
3. Multi-Modality Support
QM’s stack is modality-agnostic:
Superconducting qubits
Trapped ions
Neutral atoms
Spin qubits
Photonics
This is a major differentiator vs. control stacks tied to a single hardware approach.
Achievements & Market Position (2023–2026)
Deployment & Ecosystem Reach
QM states its technology is used by more than half of the companies building quantum computers globally.
Systems deployed in 30+ countries, across academia, national labs, startups, and large tech firms.
Their control stack is reportedly used inside Google’s Willow quantum program, though often quietly.
Strategic Partnerships & Integrations
NVIDIA:
Joint development of DGX Quantum (quantum-accelerated supercomputing infrastructure).
NVQLink integration (announced Oct 2025) for real-time orchestration between GPUs and quantum processors, critical for error correction and hybrid algorithms.
Intel Capital as investor signals alignment with semiconductor and quantum hardware ecosystems.
Qualcomm Ventures investment highlights synergies in RF control, timing, and potential edge/5G-related quantum applications.
Acquisitions & Expansion
QM has been actively buying capabilities to round out its stack:
QDevil (Denmark) – acquired in 2026 to add cryogenic control and deepen gate‑to‑qubit control solutions.
QHarbor (Netherlands) – acquired in 2026; QM opened a Delft office to expand European software operations, adding tools for automated experimentation, data management, and system-level coordination.
IQCC collaboration – QM company IQCC partnering with Quantum X Labs to evaluate AI-based quantum error-correction on QM’s control infrastructure.
These moves show a clear strategy: own the full control stack from room-temperature electronics down to cryogenic interfaces and up to experiment automation and data layers.
National & Institutional Roles
Selected by the Israel Innovation Authority (IIA) to lead the establishment of the Israel Quantum Computing Center, providing both infrastructure and its control platform.
Becoming a tenant at the Illinois Quantum and Microelectronics Park (USA), establishing a lab to support US-based quantum development.
Research Status & Technical Moat
Where QM Fits in the Research Landscape
QM is not primarily a qubit R&D lab; it’s an enabler of other people’s research:
Their hardware/software is used to run advanced protocols like randomized benchmarking, quantum error correction experiments, multi-qubit calibration, and hybrid algorithms.
Collaborations with top researchers (e.g., John Martinis, Mark Saffman, Charles Marcus) indicate deep integration into cutting-edge academic programs.
Technical Moat
QM’s competitive advantages:
Modality-agnostic control: One stack for many qubit types reduces fragmentation and locks in ecosystem dependence.
Ultra-low latency & real-time feedback: Sub‑microsecond control loops and active reset are essential for error correction and scaling.
Automation & software layer: QUAlibrate, Qolab, and QUA reduce the time from idea to experiment from months to days, creating strong user stickiness.
Strategic integrations: NVIDIA DGX Quantum and NVQLink position QM as a key piece of the emerging hybrid quantum–HPC architecture.
Together, these create a platform moat: once a lab or company builds its workflow on QM’s stack, switching costs are high.
Future Plans & Roadmap (2026–2030 Outlook)
Based on public statements, funding rationale, and product direction:
1. Scaling Control for Fault-Tolerant Machines
The $170M Series C is explicitly earmarked for:
Accelerating the roadmap for scaling quantum computers.
Developing next-generation control technologies for larger qubit counts and error-corrected systems.
Emphasis on Quantum Control Data Center concepts—centralized, high-density control infrastructure for large quantum processors.
2. Deepening Hybrid Quantum–Classical Integration
Expanding NVQLink and GPU-based orchestration to support:
Real-time quantum error correction.
Large-scale hybrid algorithms where classical and quantum workloads interleave at microsecond timescales.
3. Full-Stack Control from Gate to Qubit
With QDevil (cryogenics) and QHarbor (experiment/data layer), QM is moving towards:
End-to-end control from room-temperature electronics → cryogenic interfaces → qubit gates → experiment automation & data.
This positions them to offer turnkey control solutions for new quantum hardware startups and national programs.
4. Geographic & Ecosystem Expansion
New labs and offices:
Delft, Netherlands (Europe quantum hub).
Illinois Quantum and Microelectronics Park (US Midwest quantum corridor).
Continued expansion around the Israel Quantum Computing Center.
Expect more national and regional quantum infrastructure deals, where QM provides the control backbone.
5. Potential Capital Markets Path
While no IPO has been announced for QM specifically, the broader quantum sector is seeing public-market activity (e.g., IQM’s pre‑IPO financing and planned dual listing).
Given QM’s:
Strong investor syndicate (including Intel, Qualcomm, PSG),
Strategic national roles,
And position as a cross‑hardware infrastructure provider,
a late‑stage private round, strategic sale, or eventual public listing within the next 3–5 years is a plausible scenario if revenue and deployment metrics continue to scale.
Investment Thesis Snapshot
Bull case:
QM is the de facto standard control stack for a large share of the global quantum ecosystem.
As quantum hardware scales and error correction becomes mandatory, demand for low-latency, automated, multi-modality control grows non-linearly.
Acquisitions and partnerships (NVIDIA, Intel, national centers) deepen their moat and expand TAM beyond pure research into industrial and national infrastructure.
Key risks:
Quantum computing timelines remain uncertain; any prolonged “quantum winter” would delay spending on control infrastructure.
Potential emergence of in-house control stacks by very large players (e.g., big tech or national labs) could cap upside in some segments.
Valuation risk if private rounds have priced in aggressive adoption curves that take longer to materialize.
