Keysight Technologies

Overview

Keysight Technologies is a global electronic measurement and test instrumentation company with approximately $5 billion in annual revenue, tracing its lineage through Agilent Technologies back to Hewlett-Packard's original instrument division. Spun out of Agilent in November 2014, Keysight has methodically built one of the most complete commercial portfolios for quantum computing control electronics and test infrastructure, positioning itself as a critical supplier to virtually every major qubit modality — superconducting, trapped ion, photonic, spin qubit, and neutral atom. Its quantum strategy rests on leveraging decades of RF/microwave signal generation expertise and world-class arbitrary waveform generator (AWG) technology to supply the instrumentation backbone that quantum processors depend on, regardless of which underlying hardware platform ultimately wins.

Keysight's quantum-specific product portfolio spans signal generation, readout electronics, qubit control systems, and software layers for characterization and calibration. Key commercial offerings include the M8195A and M8196A arbitrary waveform generators (used in qubit pulse control), PXIe-based modular quantum control platforms, the KS2201A Quantum Control System designed specifically for superconducting qubit experiments, and its Quantum Engineering Toolkit (QET) software suite. The company has also developed low-noise cryogenic-compatible amplifiers and readout chains. Critically, Keysight does not compete with its customers in building quantum computers — it sells picks and shovels — which allows it to maintain deep co-development partnerships with IBM, Google, IQM, Quantinuum, and numerous national laboratories without conflict of interest.

Commercially, Keysight targets three customer segments: academic and government research institutions (currently the largest buyer base for quantum test equipment), quantum hardware companies scaling from prototype to production, and increasingly, industrial and defense customers integrating quantum sensing and communications. The company's go-to-market leverages its existing global sales force of over 4,000 engineers who already call on semiconductor fabs, aerospace and defense primes, and telecommunications companies — providing quantum with a distribution advantage that pure-play startups cannot replicate. Keysight has also invested in quantum software and calibration tooling, recognizing that hardware margins alone may compress as competition increases.

In the competitive landscape, Keysight occupies the premium end of the quantum control electronics market alongside Zurich Instruments and Quantum Machines, with secondary competition from National Instruments (now part of Emerson), Tabor Electronics, and Zurich-based spinoffs. Its defensible advantage lies in the breadth and integration of its portfolio — a customer building a 100+ qubit system can source signal generators, vector network analyzers, spectrum analyzers, qubit control systems, and calibration software from a single vendor with unified support contracts. This systems-level integration becomes increasingly valuable as qubit counts scale and the complexity of control electronics grows non-linearly.

Leadership

Technology

Keysight's technical differentiation in quantum computing centers on its RF and microwave signal generation heritage, which translates directly into the sub-nanosecond timing precision, ultra-low phase noise, and waveform fidelity required to execute high-fidelity qubit gates. Its arbitrary waveform generators — particularly the M8195A (65 GSa/s, 25 GHz analog bandwidth) and M8196A (92 GSa/s) — are among the highest-performance commercially available instruments of their class and are used extensively in superconducting qubit control chains. The company has adapted this technology into the KS2201A Quantum Control System, a purpose-built platform for superconducting qubits that integrates pulse generation, readout signal processing, and feedback capabilities in a chassis-based architecture compatible with standard dilution refrigerator setups.
