Practical active qubit reset

on 05.03.2021 at 15:48 by andrea on Blog of Andrea Corna
Practical active qubit reset When working with qubits, it’s essential to have a reliable state preparation. The easiest method for superconductive qubits is to passively wait for the qubit to decay into its ground state, but it’s slow and has […]

Automating IQ mixer calibration on the HDIQ

on 03.02.2021 at 22:43 by Chunyan Shi on Blog of Chunyan
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 […]

How to Generate QAM Signaling with the HDAWG Arbitrary Waveform Generator

on 25.11.2019 at 12:24 by Mehdi on Blog of Mehdi Alem
Introduction  Digital modulation is extensively used in telecommunications, radar systems and quantum technologies. Corresponding to every analog modulation technique, i.e. amplitude modulation (AM), phase modulation (PM) and frequency modulation (FM), there is a digital version of signal modulation: amplitude-shift keying […]

Pseudo-random number generator in the run time of AWGs

on 08.11.2019 at 14:34 by claudius on Blog of Claudius Riek
This post discusses ways to generate noise signals within a well-defined frequency range, amplitude, defined distribution (white, Gaussian, etc.), and minimal correlation using Arbitrary Waveform Generators (AWG). Sample-by-sample programming of the waveform leads to very well-defined properties, but the signal […]

Are your parametric two-qubit gates limited by the driving AWG?

Noise PSD of Zurich Instruments HDAWG
No, is the short answer, if you are using a Zurich Instruments HDAWG. ? Here is why Parametrically modulated superconducting qubit gates (parametric gates) are usually accomplished by RF-modulation – typically several hundred MHz – of the flux through a […]

Generation of Single-Sideband Modulation by Arbitrary Waveform Generators

on 15.12.2017 at 17:32 by Mehdi on Blog of Mehdi Alem
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 […]
