spinqick.helper_functions.xtalk

Functions for interfacing with crosstalk parameter registers.

Functions

gen_to_xtalk_ch(gen)	Convert generator number to crosstalk matrix index.
perp_gen_to_perp_ch(perp_gen, victim_gen)	Calculated the correct register number for the victim and perpetrator channels.
set_xtalk_element(perp_gate, victim_gate, xtalk, soc, ...)	Set crosstalk matrix element for a perpetrator, victim pair. The victim gate will respond to

Module Contents

spinqick.helper_functions.xtalk.gen_to_xtalk_ch(gen)

Convert generator number to crosstalk matrix index.

Channel 5 is the first xtalk channel.

Parameters:

gen (int)

spinqick.helper_functions.xtalk.perp_gen_to_perp_ch(perp_gen, victim_gen)

Calculated the correct register number for the victim and perpetrator channels.

Parameters:

• perp_gen (int) – qick generator number for the perpetrator channel

• victim_gen (int) – qick generator number for the victim channel. This channel will compensate when the perpetrator channel output changes, and not the other way around.

spinqick.helper_functions.xtalk.set_xtalk_element(perp_gate, victim_gate, xtalk, soc, hw_cfg)

Set crosstalk matrix element for a perpetrator, victim pair. The victim gate will respond to changes in the perpetrator gates voltage by xtalk*perpetrator voltage.

Parameters:

• perp_gate (spinqick.helper_functions.spinqick_enums.GateNames) – name of perpetrator gate

• victim_gate (spinqick.helper_functions.spinqick_enums.GateNames) – name of victim gate

• xtalk (float) – A crosstalk matrix element value between -1 and 1.

• soc – XtalkSoc object. You need to initialize the qick board with the XtalkSoc class instead of the QickSoc class to be able to use this.

• hw_cfg (spinqick.models.hardware_config_models.HardwareConfig)
