• Sample assignment to each available Queue.
• Wiring configuration specific for each Queue.

3. Bridge

• IQ Calibration

4. Benchmark

• Quality factor Estimation
• Population Estimation (Fidelity)

Loading

6. User

User need to register and will be granted certain level of access into the platform.

7. Sample

Sample will be logged for each run of measurement.

8. Queue

Enter the Queue after checking every details about the sample is correct & appropriate. Each Queue can run in parallel to each others.

• CHAR: Frequency-domain measurement for basic characterization of each cavities and physical qubits. (characterize)
• QPC: Time-domain measurement for advanced Quantum Processor Control (manipulate)

9. Task

Each task has its own directive for respective measurement schemes.

• FRESP: Frequency Response
• CWSWEEP: Continuous Wave Sweeping
• SINGLEQB: Single-Qubit-ish pulse measurement
• QUBITS: Multiple Qubits Orchestration

10. Story

Automatically telling unique story for each sample based on the notes taken by user. (coming soon)

Scripting

1. Parameter & Perimeter

• Wiring

• Waveform / Rhythm:

    <start> to <stop> * <steps> <' r ' or '^'> <repeat>
  

  Examples:

  -3 to 3 \*600 r 300 means -3, -2.999, ... 2.998, 2.999, 3 with each point repeating for 300 times.

  -1 to 1*200 ^100 means -1, -0.999, ... 0.998, 0.999, 1 with each point repeating for 100 times.

2. Pulse Sequencing

2.11 SCORE: SCripted ORchestration of Entanglements

"Musical" score dedicated for each DAC channel to orchestrate the train of pulses.

ns=<period>,mhz=<'i' or 'q'>/<IF-rotation>/<mixer-module>; 
<shape-1>/<parameter-i>/.../<parameter-f>,<pulse-width>,<pulse-height>;
...
<shape-n>/<parameter-i>/.../<parameter-f>,<pulse-width>,<pulse-height>;

Available Shapes: Flat, Gauss, Gaussup, Gaussdn, dGauss, dGaussup, dGaussdn

2.12 MACE: Modular Assembly of Commanders' (Continuous) Execution

Flexible mace to control multiple parametrized pieces of constant modules. The set of skills a commander possesses will be stored in DR-settings.

<skill-1>: {R1}, <skill-2>: {R2} ... <skill-n>: {Rn}

2.2 R-JSON

A JSON-format statement with the capability to Relate each MACE and SCORE to perform all sorts of measurements and benchmarkings.

{
"<parameter in SCORE>" : "<value or waveform assigned>",
"<comma-separated parameters> > <formula or function made from the comma-separated parameters>" : "0",
...
}
