The OPX1000 delivers high analog performance: It offers a bandwidth of 750 MHz and low 1/ f noise, and it supports 2 gigasamples/s and both direct mode (1 V pp) and amplified mode (5 V pp) with a fast, clean step response. The system provides high-speed data sharing between the different front-end modules (FEMs) and between different OPX1000 devices, which allows multiple FEMs to run calculations together. According to the company, with up to 10 field-programmable gate arrays, the OPX1000 offers the highest classical processing resources available in any dedicated quantum control solution. The scalable, modular system features up to 64 output and 16 input channels. Bristol Instruments Inc, 770 Canning Pkwy, Victor, NY 14564, Quantum Machines designed its OPX1000 ultrahigh-speed quantum controller to address the demands of the largest quantum computers. It uses a standard HeNe laser as the wavelength reference. For less exacting experiments, the company offers the more economical model 671B with an accuracy of ☐.75 ppm. To achieve the highest accuracy, the model 671A uses a single-frequency HeNe laser that is stabilized using a balanced longitudinal mode technique. This is an ideal reference source because its wavelength is well known and fixed by fundamental atomic structure. To achieve reliable accuracy for demanding applications, the 671 laser wavelength meters are continuously calibrated with a built-in helium–neon (HeNe) laser. The most precise instrument in the 671 product family, it provides an accuracy of ☐.2 ppm in the 1.5–5 µm spectral range and an accuracy of ☑ ppm in the 5–12 µm spectral range. The 671A-MIR supports the characterization of free-space, mid-IR lasers operating in a broad spectral range. Zurich Instruments AG, TechnoparkstraZürich, Switzerland, Bristol Instruments has added the model 671A-MIR to its 671 series of laser wavelength meters. With its 56 ZSync ports, QHub connects systems suitable for quantum processors with up to 300 superconducting qubits. Users can program the instrument to optimize for rapid tune-ups and error correction the processing can be adapted to the specific algorithm and computer architecture used. Through a dedicated interface, it enables precise, reproducible timing synchronization across components and ensures that readout and gate operations on separate channels are aligned and stable in time. The QHub synchronizes up to 448 microwave channels. According to the company, unlike many other commercial control solutions, its quantum computing control system is designed with a central feedback architecture that provides low and equal latency between all endpoints to optimally support error-correction technologies. The QHub orchestrates in real time all the high-speed electronic components required to control a quantum computer. The MathWorks Inc, 1 Apple Hill Dr, Natick, MA 01760-2098, To help quantum computing researchers meet the challenge of scaling up quantum computers, Zurich Instruments has brought to market its QHub Quantum System Hub. R2023b also features updates to MATLAB and Simulink tools, including the Aerospace, Predictive Maintenance, Signal Integrity, and Wavelet Toolboxes. ![]() With the Polyspace xUnit application programming interface or a graphical test-authoring editor, users can create stubs (simulations of methods or objects) and mocks (for verification of the behavior of code) to make component testing simpler and more efficient. R2023b also includes Polyspace Test, which enables users to develop, manage, and execute C and C++ code tests in embedded systems. ![]() When paired with the Requirements Toolbox, Simulink Fault Analyzer helps users create and document formal connections between faults, hazards, fault detection and mitigation logic, and other artifacts. They can time or trigger faults by specific system conditions and perform safety analyses, such as failure mode and effects analysis. Simulink Fault Analyzer lets users carry out fault injection simulations without modifying engineering designs. Release 2023b (R2023b) of MathWorks MATLAB and Simulink software introduces two new products and major updates that simplify model-based design and streamline workflows.
