Frequency-multiplexed readout of qubits is at the heart of superconducting quantum processors and an essential step for scalable architectures. The UHFQA Quantum Analyzer is specifically tailored for this challenge and brings the latest technology to work in your lab – […]

DC I-V Sweeps on the MFIA

on 10.01.2020 at 09:07 by Tim Ashworth on Blog of Tim Ashworth
Characterizing the impedance of components and materials with the MFIA is done by necessity with an AC signal. However, the MFIA and MFLI can also take DC measurements. This blog post shows how easy it is to take DC measurements, […]

Electrochemical Impedance Spectroscopy of Tap Water with the MFIA

on 06.01.2020 at 18:09 by Meng on Blog of Meng Li
Introduction Electrochemical impedance spectroscopy (EIS) is a popular non-destructive technique to characterize the physicochemical properties of materials, particularly at the solid-liquid (or electrode-electrolyte) interface. Despite the complexity of the measured data, EIS can be used to study many electrochemical devices […]

A deep dive into data acquisition with the DAQ tool

on 25.11.2019 at 14:21 by moritz on Blog of Moritz Kirste
Introduction Looking at the heart of experimental science you will find data acquisition. Why? Because even the most perfectly conceived experiment is worth nothing if nobody acquires, analyzes and stores data for further analysis and reproduction of results. Despite its […]

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 […]

Bioimpedance of a Muscle Contraction with the MFIA

on 22.11.2019 at 09:20 by Tim Ashworth on Blog of Tim Ashworth
Impedance measurements of biological tissue are commonly used in bio-engineering and life sciences to assess the condition and composition of tissue in a non-invasive, reproducible way.  In addition, bio-impedance measurements, also known as bioelectrical impedance analysis (BIA) or electrical impedance […]

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 […]

AWG Precompensation for high-fidelity CZ gates in transmon qubits

on 02.11.2019 at 10:44 by Chunyan Shi on Blog of Chunyan
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 recent publication, Rol et […]

很多器件和材料的阻抗都受到频率和其它参数(例如DC偏置电压)的影响。为了能够完整的表征这些样品,我们需要一种能在两个维度下进行参数扫描的阻抗分析仪。通过使用LabOne自带的任意5个API之一,我们可以轻易控制MFIA阻抗分析仪(或者MFLI锁相放大器和MF-IA升级选件)来进行这种全面参数分析。本文将详细说明如何使用简短的Python 3.7的程序,进行多参数维度的阻抗扫描。

阻抗分析仪的精度是一个重要指标,它定义了器件或样品的实测阻抗和真值的区别大小。因为阻抗分析仪的精度会随着频率和阻抗大小而变化,因此我们使用一种能体现出仪器所能达到的最高精度的指标,即为基本精度,与此同时也能够对不同仪器做横向比较。MFIA阻抗分析仪的基本精度区间很宽,在1 Ohm到1 MOhm和 1 mHz到500 kHz范围内,MFIA可以达到0.05%的基本精度,这对表征不同器件和材料很有帮助。
