Quantum Machines

Enabling Tech

Quantum Machines develops the OPX+ pulse processor — a purpose-built classical processor for real-time quantum control that handles the precise pulse sequences needed to manipulate qubits. The company's Quantum Orchestration Platform provides low-latency feedback loops essential for error correction. Quantum Machines works across all qubit modalities and has partnerships with major quantum computing labs worldwide. It is part of NVIDIA's NVQLink ecosystem for GPU-QPU integration.

Qblox

Enabling Tech

Qblox is a QuTech spin-out that engineers scalable control electronics for quantum computers. Its modular Cluster system provides high-fidelity microwave control and readout for superconducting, spin, and NV center qubits. Qblox supplied the control stack for the Q-PAC system (the first commercially deployable open-architecture quantum computer in the US) and was selected by DOE/Fermilab to manufacture the QICK quantum control platform. Partners include Bluefors (cryogenic integration), Q-CTRL (calibration), and QuantWare.

Zurich Instruments

Enabling Tech

Zurich Instruments introduced the first commercial Quantum Computing Control System (QCCS) in 2018 and remains a leading provider of test and measurement instrumentation for quantum computing. Acquired by Rohde & Schwarz (a $3B test-and-measurement company), Zurich Instruments benefits from global service infrastructure and deep RF engineering expertise. The QCCS was selected for Fujitsu and RIKEN's 256-qubit superconducting system in Japan. The system operates directly at qubit frequencies without mixer calibration.

Keysight Technologies

Enabling Tech

Keysight is a $30B+ market cap test and measurement company (spun out of Agilent/HP) that has developed quantum control solutions alongside its core electronic measurement business. Keysight provides arbitrary waveform generators, digitizers, and signal analyzers used across quantum computing labs worldwide. It is part of NVIDIA's NVQLink partner ecosystem for GPU-QPU integration and serves as the 'picks and shovels' play for quantum — its instruments are needed regardless of which qubit modality wins.
