Webinars

Would you like to understand and address materials losses that are a key obstacle for the next generation of quantum technology? This webinar details how low-noise measurements with lock-in amplifiers can help you optimize your materials. Jim Phillips explains Hall measurements, RF reflectometry for quantum dot stability diagrams, and the Pound-Drever-Hall (PDH) technique for resonator characterization.

Professor Corey Rae McRae of CU Boulder and NIST Boulder dives into the use of microwave resonators as a tool to better understand superconducting qubit materials at millikelvin temperatures and ultralow powers. We show recent results using PDH to perform resonator center frequency and Q-factor measurements faster than is possible with the traditional VNA method.

Would you like to start qubit measurements, but don’t know how? Do you already do qubit measurements, but would like to learn tips and tricks to simplify and speed them up?

This webinar introduces essential methods used in superconducting qubit characterization: qubit spectroscopy, single-shot readout, and Rabi oscillation measurements. Through tutorials and demonstrations, we lead you from theory to practical, experimental measurements carried out on a real qubits in a dilution refrigerator. The webinar brings together device physics, instrumentation know-how, and software, all essential to realize state-of-the-art quantum experiments.

Quantum technologies progress towards useful applications at a tremendous pace, with different technological platforms and approaches being explored. As key enablers of control and measurement solutions for quantum computing applications, Zurich Instruments and Rohde & Schwarz brought together researchers in quantum technologies working in different areas and facing distinct challenges but share core competencies and important know-how.

In this video, Jan, Tobias and Bruno present the SHFQC Qubit Controller and discuss how this instrument can help speed up system tune-up and complex algorithm execution. The presentation includes practical demonstrations showing how to use the SHFQC to control, read out and perform fast feedback on up to 6 superconducting qubits with a single instrument, as well as a discussion of how the SHFQC can be integrated into larger qubit control systems. The answers to the questions asked during the live event are summarized in this blog post.

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.

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.

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.

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.
