Connecting to SHFQC by Zurich Instruments in Python

Instrument Card

The SHFQC Qubit Controller can control, read out and provide fast feedback on up to 6 superconducting qubits. It integrates the functionality of the SHFQA Quantum Analyzer, the SHFSG Signal Generator and more in a single instrument.

PROTOCOLS > SCPI

📄 IDN

Query a device's identity through the universal *IDN? SCPI command.

📄 MEASURE VOLTAGE

Query an instrument's measured output voltage, such as a DMM or power supply.

📄 SCPI WRITE

Write a SCPI command to a connected bench-top instrument and return the result.

QCodes

To connect to a SHFQC Qubit Controller using Qcodes, you can use the following code:

import qcodes as qc
from qcodes.instrument_drivers.zhinst import SHFQC

# Connect to the SHFQC Qubit Controller
shfqc = SHFQC("shfqc", "dev1234")

# Print the available SGChannels
print(shfqc.sgchannels())

# Print the available QAChannels
print(shfqc.qachannels())

# Print the available Scopes
print(shfqc.scopes())

# Close the connection to the SHFQC Qubit Controller
shfqc.close()

This code imports the necessary modules and creates an instance of the SHFQC instrument driver. You can then use the sgchannels(), qachannels(), and scopes() methods to print the available SGChannels, QAChannels, and Scopes, respectively. Finally, the close() method is called to close the connection to the SHFQC Qubit Controller.
