LabOne Q Software User Manual

With Zurich Instruments LabOne Q, you will experience complex setups as a single machine with intuitive programming in a Python-based domain-specific language, while keeping full control over hundreds of channels. It maximizes system uptime through fast quantum circuit updates and increases the lab throughput by allowing for automated tune-up and calibration.

LabOne Q enables you to define basic characterization experiments as efficiently as complex quantum circuits, such as quantum error correction. LabOne Q is also tailored for optimized scheduling of custom gates, pulses, and waveforms with ultrafast playback and decision logic and waveform replacement thanks to optimized code generation and code execution for Zurich Instruments' advanced signal generators and quantum analyzers.

The Introduction chapter will give you a technical overview of the software, and the Installation and Hello LabOne Q sections will get you up-and-running quickly. You can also consult the Workflow chapter to see how experiments in LabOne Q are structured or dive right into a single qubit characterization experiment.

Intuitive Programming

With LabOne Q, you will take full advantage of Zurich Instruments' system control approach. The software takes care of programming individual Zurich Instruments' quantum computing products and third-party devices, executing experiments and retrieving measurement results while ensuring synchronization and control through one software interface (API). You will define experiments independently of an instrument setup in the domain-specific language (DSL) in Python, and you can manage the connection and execution of experiments on your desired hardware within a session. You don’t need to program the instruments directly (though you have the ability to!); instead, you can focus on scheduling your experiment along with the required gates and pulses directly on the whole quantum system.

High Uptime

LabOne Q separates code generation, handled by the compiler, and execution, handled by the controller. This approach optimizes the balance between execution in the software and on the hardware within and outside of a qubit’s coherence time. While the optimization in the Compiler affects code generation, users maintain full control of the pulses at the sample level within the abstract definition of their quantum circuits in the DSL. LabOne Q guarantees sample-precise radio frequency pulses with optimal operation on the QCCS hardware, so that the burden of optimizing code and resources does not weigh on the experimenter. Users benefit from a maximized usage of the quantum processing unit that enables them to define and schedule experiments continuously, thus achieving a high quantum computer uptime.

Optimized Scheduling

LabOne Q is designed for demanding applications such as error correction protocols, surface code implementations, waveform replacement, and randomized benchmarking on many qubits. Parametric control of pulses, dynamic pulses, modulation frequency and phase updates, real-time branching for feedback, and call-back to user-defined pulse libraries on a higher level are all possible with optimized waveform memory usage and memory-efficient code generation by the compiler and the controller.

Users can easily move from gate to pulse level and to sample-precise control as they program their quantum algorithm or characterization experiments; LabOne Q takes care of scheduling each experiment on Zurich Instruments' hardware.
