Quantum Control Made Easier: Turbocharging OPX+ with QOP V2.2

The world of quantum computing continues to evolve rapidly, and Quantum Machines is at the forefront of these advancements. QOP firmware V2.2 is the latest upgrade to OPX+, our best-in-class quantum control system. Powered by QM’s unique Pulse Processing Unit (PPU), which integrates real-time processing and control flow, OPX+ can process even the most advanced quantum algorithms at ease. It’s also amazingly easy to program. (see our previous post about the Asteroids arcade gaming over OPX here and read more on OPX+ on our website).

Quantum controllers operate within quantum coherence timescales, making software upgrades alone inadequate in enabling genuine quantum advancements. That’s why we at QM go beyond mere software updates and elevate the OPX’s functionality by upgrading its logic through firmware updates. Each release feels like acquiring a brand-new controller – only without the hassle of reinstalling, rewiring and recalibrating the system.

In this blog post, we’ll delve into the two of the six key features introduced by QOP V2.2 firmware, highlighting how they empower you to design, execute, and test your quantum circuits with unprecedented control and ease.

Enhanced Circuit Verification and Simulation

Accurate circuit verification and simulation are crucial for successful quantum experiments. QOP V2.2 introduces two complementary features that revolutionize this aspect.

The first tool we introduce to enhance verification is printing the time at which each given command has been executed. Indeed, users can now access the command timestamps, allowing precise tracking of any play() and measure() commands in the code. This feature is particularly useful for tracking qubit phases during operations and accurately measuring delays between pulses when performing real experiments. 

Additionally to the timestamps, the OPX Simulator, which emulates  all analog and digital outputs, has also been updated. Our simulator is a highly integrated quantum hardware simulator. It seamlessly accepts pulses from a virtual OPX programmed in QUA and produces raw measurement outputs for further processing by the digital OPX.

With this new release, the simulator now provides detailed reports, plots, and waveform visualizations. The waveform report holds all the information associated with a specific command on each single qubit. Additionally, this information can be easily plotted and sorted, enabling in-depth analysis of quantum circuits at the pulse level. Just by hovering on the web interfaced plots, you can see all the metadata. Can’t be easier than that!

Cluster Creation and Device Management 

The OPX+ is designed uniquely to support multiple devices concurrently, allowing multiple research groups to carry out different experiments simultaneously using a single control system. It is a feature that is especially beneficial in an environment where multiple, parallel quantum research operations are undertaken, optimizing resource utilization and obviating the need for each group to have separate control systems.

The introduction of QOP v2.2 brings additional enhancements that improve the way users interact with multiple devices from Quantum Machines. This update introduces a new Admin panel equipped with an intuitive Graphical User Interface (GUI). This user-friendly interface allows for automatic detection and identification of devices, streamlining the tasks of network management and device integration. Creating multiple custom clusters of Quantum Machines’ devices becomes as straightforward as dragging and dropping within the GUI, offering greater flexibility and convenience.

In addition to its ease of use, the new GUI also provides valuable insights into the functional status of clusters and their connectivity. These insights significantly facilitate debugging, making it easier to identify and resolve potential issues.
