Echo sequence
Solid state qubits are typically characterized and operated by a series of very short pulses. To achieve a high-fidelity control, it is necessary to generate many sequences of them, with very accurate timing. In this blog post, I will show […]

The LabOne Multi-Device Synchronization feature

on 24.08.2021 at 08:53 by Paolo Navaretti on Blog of Paolo Navaretti
In this blog post we want to present a lesser known but very powerful LabOne tool freely available to all Zurich Instruments users: Multi-Device Synchronization (MDS). Although all Zurich Instruments lock-ins and impedance analyzers are equipped with multiple demodulators either natively […]

Bell State Stabilization of Superconducting Qubits with Real-time Feedback

on 18.08.2021 at 09:40 by Bahadir Dönmez on Blog of Bahadir
Bell state stabilization with real-time feedback is a key milestone for the implementation of surface code [1], which is one of the most promising quantum error correction codes for building large-scale quantum computers [2]. Fundamental requirements for realizing this code […]

Impedance Characterisation of Wearable Capacitive Sensors

on 18.08.2021 at 08:14 by Tim Ashworth on Blog of Tim Ashworth
This blog post explains how the MFIA can be used to characterise wearable capacitive sensors and introduces two recent published studies where innovative flexible wearable sensors have been developed which operate on the principle of capacitive sensing. Both of these […]

Noise Spectral Density Measured with Lock-in Amplifiers

on 15.08.2021 at 12:25 by Mehdi on Blog of Mehdi Alem
Introduction Proper noise characterization is essential in many applications, especially when dealing with tiny signals buried in noise like in nanotechnology, photonics, and quantum physics. Noise characteristics of a system are often represented by the noise spectral density either in […]

A LabVIEW Template for building DLTS systems based on the MFIA

on 27.07.2021 at 09:39 by Roberto Foddis on Blog di Roberto Foddis
This blog post describes how to get started writing a LabVIEW code to control the MFIA for DLTS measurements. It also includes ideas for independent code for the control of a third-party Temperature Controller. Deep Level Transient Spectroscopy (DLTS) is […]

Loudspeaker Impedance Measurements with the MFIA

on 26.07.2021 at 12:36 by Meng on Blog of Meng Li
Loudspeakers are electroacoustic transducers that convert electrical signals into acoustic ones. They are commonly seen and heard in our daily life. One of the most frequently used types, known as an electrodynamic loudspeaker, functions by the movement of a cone […]

DLTS User Meeting 2021 Q&A

on 19.07.2021 at 06:05 by Tim Ashworth on Blog of Tim Ashworth
Deep level transient spectroscopy (DLTS) is a powerful and commonly used technique to investigate the concentration and carrier binding energy of semiconductor defects by measuring capacitance transients at different temperatures. As such, it is a critical tool for the characterization of […]

How to characterize magnetic materials using lock-in amplifiers: A Zurich Instruments and Cryogenic webinar summary

on 15.07.2021 at 11:00 by Jelena on Blog of Jelena Trbovic
In this webinar we covered two basic magnetic characterization techniques, the vibrating sample magnetometry (VSM) and AC susceptibility where lock-in amplifiers are essential part of the measurement and the detection chain. We teamed up with Yury Bugoslavsky who is managing […]

Low-Frequency DLTS of Perovskite Solar Cells with the MFIA

on 29.06.2021 at 00:19 by Tim Ashworth on Blog of Tim Ashworth
Deep level transient spectroscopy (DLTS) is a powerful and commonly used technique to investigate the concentration and carrier binding energy of defects in semiconductors. The technique involves measuring capacitance transients at different temperatures, typically at 1 MHz. However, DLTS can also […]

Evaluate Interdigitated Electrode Sensors with the MFIA

on 16.06.2021 at 15:45 by Meng on Blog of Meng Li
In the previous blog posts, we demonstrated conductivity and permittivity measurements of liquids using an MFIA impedance analyzer. To reach the best accuracy, the measurements were carried out using immersion probes or dielectric fixtures with a precisely defined electrode area […]

Impedance Measurements with Small Amplitude Test Signals

on 03.06.2021 at 19:17 by Tim Ashworth on Blog of Tim Ashworth
When taking an impedance measurement, the test signal amplitude can often be a factor which needs to be minimised to avoid unnecessarily disturbing the sample under test. This blog post presents measurements showing how even small test signals of just […]

Take Your Dielectric Measurements to the Liquid State

on 25.05.2021 at 14:06 by Meng on Blog of Meng Li
Liquid dielectrics are dielectric materials in a liquid state and are widely used in electrical insulation as well as cooling. Nonetheless, their fluidity also makes accurate dielectric measurements a challenge. In a previous blog post, we saw how to measure […]

How to configure the DAQ module for image acquisition
