Location: Remote
This repository hosts the Qutrit Calibration package, an extension for Qiskit Experiments designed to facilitate the calibration of single-qutrit gates. By expanding the standard qubit calibration routines to the third energy level ($|2\rangle$ state), this toolkit enables researchers to explore qutrit physics and higher-dimensional quantum simulations.

Key Features
The package provides a suite of experiments to tune up the $|1\rangle \leftrightarrow |2\rangle$ transition (EF transition) gates, including SX12, X12, Sy12, Y12, and RZ12.
Supported calibration experiments include:
- Spectroscopy:
NarrowBandSpectroscopyCalfor identifying the $|1\rangle \leftrightarrow |2\rangle$ transition frequency. - Amplitude Calibration:
RoughEFAmplitudeCalandFineEFXAmplitudeCalfor tuning pulse amplitudes. - Frequency Calibration:
RoughEFFrequencyCalfor coarse frequency adjustments. - DRAG Calibration:
RoughEFXDragCalfor optimizing pulse shaping to reduce leakage.
Research Contributions
Our spin-1 AKLT models directly led to the development and deployment of transmon qutrit calibration codes in the Qiskit Community project:
- Implemented AKLT ground-state simulations on superconducting qubits
- Contributed to transmon qutrit calibration methodology
- Collaborated with the Qiskit Community on quantum circuit optimization
Note: This project is currently in an alpha release state. It serves as a foundational tool for enabling advanced research, such as the simulation of AKLT models and other spin-1 many-body systems on superconducting hardware.
