Automating IQ Mixer Calibration on the HDIQ

03.02.2021

As a crucial step in the bring-up of superconducting experiments, IQ mixer calibration normally requires multiple instruments from different parties and manual cabling work. This blog post describes how to use the Zurich Instruments HDIQ, HDAWG and UHFQA (or other UHF instruments) to automate IQ mixer calibration and: Simplify the...

AWG Precompensation for High-Fidelity CZ Gates in Transmon Qubits

02.11.2019

High quantum gate fidelity is essential for all quantum hardware platforms. Temporal sensitivity to flux noise and flux pulse distortion can pose major limitations to achieving high fidelity with repeatable two-qubit gates in transmon qubits. In a recent publication, Rol and collaborators demonstrated a fast (40 ns), low-leakage (0.1%), high-fidelity...

Are Your Parametric Two-Qubit Gates Limited by the Driving AWG?

13.09.2019

If you are using the Zurich Instruments HDAWG, the answer is no. Let's see why. Parametrically modulated superconducting qubit gates (parametric gates) are usually accomplished by RF-modulation – typically several hundred MHz – of the flux through a mediating coupler element or qubit. Usually, many dBm of signal power are...

Generation of Single-Sideband Modulation by Arbitrary Waveform Generators

15.12.2017

Introduction I/Q modulations are extensively used in a variety of applications including telecommunications, quantum computing (QC), nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR) spectroscopy and band-excitation atomic force microscopy (AFM). In this post, we demonstrate how to generate such signals using arbitrary waveform generators from Zurich Instruments with an...
