Dear all, In today's QIBO meeting we debated over whether flux pulses should be applied on top of a constant bias (relative to the sweet spot biassing value) or use...
Similar to what it is being performed with QM, and once https://github.com/qiboteam/qibolab/issues/900 is completed, a routine would be necessary to calibrate mixers using resonators and qubits' responses. This routine is...
Hi, The current implementation of `qubit_crosstalk` does not yet provide the crosstalk copensation matrix so that one could calculate the set of biases to be applied to qubits as a...
The current implementation of single shot classification does not distinguish between state e and any higher states. This results in an inaccurate evaluation of the readout fidelity. When used to...
The colour scheme used in `classification.py` asigns red for ground state and blue for ground state. In all papers I read they assign, blue for ground and red for excited...
Many of the probabilities routines: - rabi_amplitude - rabi_length - ramsey - t1 - t2 use as `SINGLESHOT` as their default `averaging_mode`. This severely limits the amount of points that...
Hi, the `train_qubit` method of qibocal/fitting/classifier/run.py, called as part of `protocols.characterization.classification` dumps data to the folder used to launch the script: ```python base_dir = pathlib.Path() ... def train_qubit( cls_data, qubit:...
Hi, In order to be able to calibrate the mixers of RF modules, the driver should expose the following parameters: - module `outX_offset_path0` - module `outX_offset_path1` - sequencer `mixer_corr_gain_ratio` -...
Hi, It would be nice to have routines that help us characterise the noise. CPMG is one such routine. https://www.nature.com/articles/nphys1994 The implementation of this routine (in RT) requires advanced sweepers...
Hi, Several routines that sweep qubit drive pulse duration do not adjust the start of the readout pulse. - [ ] rabi_length_msr - [ ] rabi_length - [ ] t2...
