Fully-integrated control stacks for quantum computing, part 2: step-by-step example experiments*

In this talk, we demonstrate the fully-integrated control stack for quantum computing with two concrete examples: the characterization of transmon qubits and tuneup of quantum dots. For each, we go step-by-step through the stack: 1) We define experiments in the Quantify-Scheduler* as deterministically-timed operations with parameterized amplitude, offset, and modulation. 2) These abstract operations are converted into pulses and readouts which can be examined by the built-in visualization tools. 3) The schedules are compiled to pulse envelopes and hardware-executable programs (Q1 Assembly) which are uploaded to the hardware. 4) The experiment is executed by the Qblox Cluster which directly outputs and inputs all signals. The processed (integrated & averaged) measurement outcomes  (up to 131k) are returned to the user. 5) Live plotting and data analysis tools are used for data visualization and interpretation. An extensive set of free and open-source experiment libraries allow for plug&play qubit characterization and save time for further, more sophisticated qubit operations.

*The Quantify consortium consists of Qblox and Orange Quantum Systems.
