Romain Stomp (romain.stomp@zhinst.com)
In this video, Prof. Peter Grutter provides an overview of his current research aimed at developing ultrafast laser methods combined with AFM to gain a better understanding of charge dynamics at the molecular time and length scales. He then presents his most recent results on mechanically detecting single electrons for single-molecule spectroscopy. The outlook of his talk addresses plans to adapt these methods to elucidate the energetics of organic charge transfer systems as well as the quantum properties of single and coupled dopants in silicon. Following Prof. Grutter's talk, Application Scientist Romain Stomp illustrates how the discussed methods can be implemented with Zurich Instruments' rich toolbox. The answers to the questions asked during the live event are summarized in this blog post.

Heidi Potts (heidi.potts@zhinst.com)
As the size of electronic devices goes down to few nanometers, interfaces become increasingly relevant and often dominate and interfere with a device's performance. Hybrid devices are a particularly good example, because they rely on interfacing materials with different physical properties to control superconductivity, spin or other carrier characteristics in the active parts of the device. The performance of these structures depends critically on their reliable fabrication and interface characterization. In this webinar, Jelena Trbovic and Heidi Potts take you from general interface considerations to nanodevice characterization with lock-in amplifiers: you learn how to set up low-noise measurements and how to characterize devices on ultrafast timescales using RF reflectometry. The answers to the questions asked during the live event are summarized in this blog post.

Clemens Müller (clemens.mueller@zhinst.com)
In this webinar, Ed, Jim, Jelena and Clemens look at how lock-in amplifiers offer a prime way to probe and understand material properties relevant for qubit coherence while keeping measurement times and complexity to a minimum. They discuss the basic working principles of semi- and superconducting qubits and demonstrate how to characterize frequency and loss fluctuations in readout resonators, as also summarized in this blog post.

Kıvanç Esat (kivanc.esat@zhinst.com)
In this webinar, Kıvanç Esat is joined by Dr. Tomás Manzaneque García (TU Delft) to look into the best practices for the characterization of a sensor with lock-in amplifiers. Kıvanç and Tomás cover practical examples including mechanical micro-resonators and optomechanical systems, they show how to set up feedback controllers for maximal precision and review the existing trade-offs between open- and closed-loop operation. A summary of the answers to the questions asked during the live event can be found in this blog post.

Bruno Küng (bruno.kueng@zhinst.com)
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.
