Anritsu

Signal generators and analyzers for qubit-control labs

Published by FyncaResearch checked How we research

Where it fits in a quantum computer

Anritsu’s quantum computing page presents its signal generators as local oscillators for the up- and down-conversion stages of qubit control, alongside spectrum, phase-noise and multiport vector network analyzers for calibrating cryostat RF paths. Researchers at AIST and Japanese universities testing a superconductor-logic qubit controller chip generated its two-tone LO signal with an Anritsu MG3710A and read its outputs on an Anritsu MS2830A analyzer (npj Quantum Information, June 3, 2024).

What the evidence establishes

Lab & test products

Disclosed: Anritsu’s quantum computing page positions its signal generators as qubit-control local oscillators; the AIST paper documents lab use, not a production system.

A documented cryogenic, vacuum, microwave or test-and-measurement product used in physics labs or electronics test. Adoption in quantum computers is not established by the cited source.

Keep in perspective

Anritsu names no quantum-computer customer, and the AIST work is a laboratory test of a controller chip. Its instruments are general-purpose test equipment with no disclosed quantum revenue.

Diversified business exposure. This describes the breadth or role of the business; it is not an investment rating. A quantum-computing product, design-in or partnership does not by itself establish material quantum revenue, market share, or future returns.

Connections to the assembly

These links explain the technology relationship. The model is illustrative and does not represent an actual manufacturer’s bill of materials.

Microwave sources & mixers

Local oscillators, synthesizers and IQ mixers that move pulses up to the qubits’ 4–8 gigahertz band and bring the readout signal back down.

Scope of the company links: Keysight’s QCS includes M5201A down converters (2–16 GHz input) alongside AWGs that output directly up to 16 GHz. In QuEL’s QuBE, Analog Devices ADRF6780 mixers and Texas Instruments LMX2594 synthesizers move 1.25–3.25 GHz waveforms up to the 7.25–10 GHz drive band, and QICK’s RF boards use ADI ADF4372 or TI LMX2594 local oscillators. Anritsu positions its signal generators as qubit-control local oscillators, with lab use documented at AIST. Controllers that synthesize microwaves directly need fewer mixers. Zurich Instruments’ SHFSG+ signal generators and QuEL’s front end are private.
