Paolo Navaretti (paolo.navaretti@zhinst.com)
Tobias Thiele (tobias.thiele@zhinst.com)
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.

Claudius Riek (claudius.riek@zhinst.com)
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.

Romain Stomp (romain.stomp@zhinst.com)
Mehdi Alem (mehdi.alem@zhinst.com)
In this webinar, Romain and Mehdi discuss how to address complex detection schemes in scanning probe microscopy (SPM) with the highest possible resolution. They carry out tutorials on Kelvin probe force microscopy (KPFM) and electrical pump-probe methods, and consider a practical example of FM-KPFM measurement using the MFLI Lock-in Amplifier with a FlexAFM microscope. Romain's blog post highlights some important take-home messages, includes useful additional resources, and summarises the answers to the many questions asked during the live event.

Tobias Thiele (tobias.thiele@zhinst.com)
In this webinar, Tobias discusses how our instruments simplify and accelerate the development of ambitious quantum computing projects going from a few to more than 100 qubits. Focusing on two of the most promising systems, namely superconducting and spin qubits, he shows how to perform Rabi oscillations within a day and how to control and read out qubits with the highest speed and fidelity. Tobias answers some of the questions asked during the live session in this blog post.

Romain Stomp (romain.stomp@zhinst.com)
In this webinar, Claudius and Romain are joined by Prof. Markus Raschke (University of Colorado Boulder) and his student Mr. Samuel Johnson to present the growing field of tip-enhanced scanning probe microscopy and its application to precision spectroscopy, ultrafast-nano-imaging and, in the strong coupling limit, cavity quantum electrodynamics. In particular, Claudius shows how to maximize the signal and image information content with advanced measurement instrumentation. Claudius, Markus and Samuel answer many of the questions asked during the live event here.

Claudius Riek (claudius.riek@zhinst.com)
In this webinar, Claudius focusses on four prototypical techniques in optics and photonics: tunable diode laser absorption spectroscopy (TDLAS), pump-probe spectroscopy, stimulated Raman scattering (SRS), and carrier-envelope offset (CEO) stabilization. He looks into how to choose the most suitable measurement scheme for your experiment, e.g. a lock-in amplifier or a boxcar averager, and discusses how to save precious measurement time and record high-quality data with the highest signal-to-noise ratio. Claudius answers the questions asked during the live session here; he covers some crucial aspects related to the topic of his webinar in this blog post.

Tim Ashworth (tim.ashworth@zhinst.com)
In this webinar, Tim looks at two impedance measurement challenges. In the first case, he shows how to measure equivalent series resistance (ESR) below 1 mOhm and equivalent series inductance (ESL) below 20 nH for a DC-Link capacitor. In the second example, he discusses how to strike a balance between measurement speed and precision in fast capacitance measurements (on the time scale of microseconds) used to investigate the transient behavior of devices and materials. Tim's answers to many of the questions asked during the live session are available here.
