Qubit Control and Measurement Solutions

Qubit Control and Measurement Solutions I Zurich Instruments Webinar
September 23rd, 2021
Speakers: Bruno Küng

Bruno Küng, Prof. Stefan Filipp (Technical University of Munich and Walther-Meißner Institute) and Max Werninghaus (Technical University of Munich) look at how the growing effort towards large-scale superconducting quantum computers calls for instruments giving access to established methods for qubit control and measurement with as little engineering overhead as possible. Prof. Filipp covers the basics of superconducting quantum computing, including recent advances in optimal control methods for maximizing qubit gate fidelity. Bruno presents how to design and operate a qubit control setup at microwave frequencies with a simple Python interface controlling the measurement instruments; Max Werninghaus carries out a hands-on demonstration of this setup on a real qubit.

Virtual DLTS User Meeting 2021

Zurich Instruments DLTS User Meeting 2021
July 8th, 2021
Speakers: Zurich Instruments team, and hosted by Magdalena Marszalek

Deep level transient spectroscopy (DLTS) is a critical tool for the characterization of all forms of semiconductors. In this first edition of the DLTS User Meeting, Zurich Instruments brought together members of the DLTS community to foster knowledge exchange and networking through scientific talks discussing semiconductor defect characterization and the effects of radiation on III-V optoelectronic devices. Detailed tutorials also covered the study of transients and data acquisition. To read the answers to the questions asked during the live event, take a look at this blog post. To discuss your DLTS challenge, get in touch with Tim Ashworth, Roberto Foddis or Meng Li.

How to Characterize Magnetic Materials Using Lock-in Amplifiers

How to Characterize Magnetic Materials Using Lock-in Amplifiers I Zurich Instruments Webinar
June 29th, 2021
Speakers: Jelena Trbovic, Yury Bugoslavsky (Cryogenic Ltd)

In this webinar, Jelena Trbovic and Yury Bugoslavsky review the basics of magnetic materials and present characterization methods taking advantage of lock-in amplifiers. In particular, Jelena and Yury discuss how to distinguish between different types of magnetic materials using magnetization characterization techniques such as those based on the vibrating sample magnetometer (VSM) and AC susceptibility. They also look at how to ensure that lock-in measurements are performed correctly. This blog post offers a summary of the webinar and includes the answers to some of the questions asked during the live event.

Virtual SPM User Meeting 2021

Zurich Instruments SPM User Meetings
May 20th, 2021
Speakers: Zurich Instruments team, and hosted by Magdalena Marszalek

Scanning probe microscopy (SPM) offers many powerful techniques to image and control microscopic objects. In this fifth edition of the SPM User Meeting, Zurich Instruments brought together SPM enthusiasts to foster knowledge exchange and networking through scientific talks discussing the latest advances on how to image functional materials (such as perovskites, solar cells and ferroelectrics), through detailed tutorials and with a round table on Kelvin probe force microscopy (KPFM). To discuss your SPM challenge, get in touch with Romain Stomp and Mehdi Alem.

The Next Generation of Qubit Control: SHFSG Launch Event

The Next Generation of Qubit Control: SHFSG Signal Generator | Zurich Instruments Webinar
April 29th, 2021

In this video, Jan, Mark and Bruno present the SHFSG Signal Generator and discuss how this instrument represents the next step for quantum computing control systems. The presentation includes practical demonstrations showing how to operate the instrument at 8.5 GHz without mixer calibration, how to maximize quantum gate fidelities thanks to high-purity signals, and how to control up to 8 superconducting or spin qubits per instrument. The answers to the questions asked during the live event are summarized in this blog post.

Probing Local Magnetic Field Patterns

Probing Local Magnetic Fields Patterns I Zurich Instruments Webinar
February 11th, 2021
Speakers: Jelena Trbovic

In this webinar, Jelena and Prof. Martino Poggio (University of Basel) look into how macroscopic manifestations of quantum mechanics involving strongly correlated states, e.g. superconductivity and magnetism, are sensitive to the local environment. Nanometer-scale spatial resolution is often required to identify the conditions for the emergence of such macroscopic behaviors. Martino talks about the basic principles and applications of magnetic imaging techniques, including NV-center and nano-wire MFM microscopy, that shed light on magnetization patterns, spin configurations and current distributions. Jelena shows how lock-in amplifiers can be used with such local probing techniques to enhance their sensitivity and contrast. In this blog post, Jelena answers the questions asked during the live session.

The Next Generation of Quantum Analyzers: SHFQA Launch Event

The Next Generation of Quantum Analyzers: SHFQA Launch Event I Zurich Instruments Webinar
November 17th, 2020

In this video, Paolo, Sadik and Tobias provide a technical overview of the SHFQA Quantum Analyzer and discuss its capabilities. Instrument demonstrations show how to measure a resonator at 8 GHz and perform the parallel readout of 16 qubits, as well as how to take advantage of the SHFQA's feedback capabilities and integrate the SHFQA into a 10-instrument Quantum Computing Control System (QCCS). The answers to the questions asked during the live event are summarized in this blog post.

Focus on Recovering Signals in Optical Experiments

Focus on Recovering Signals in Optical Experiments I Zurich Instruments Webinar
October 22nd, 2020
Speakers: Claudius Riek

In this webinar, Claudius shows how specific settings on lock-in amplifiers and boxcar averagers impact the results of a measurement in optical experiments by looking at the filter function, the filter order and the time constant. He then discusses the relevance of typical properties of electronic measurement devices for optical experiments such as the instrument's dynamic range, measurement bandwidth and signal input noise. Claudius answers the questions asked during the live session in this blog post.
