Randomized Benchmarking in Seconds


Random Benchmarking Sequence

Randomized benchmarking (RB) is a widely used tool in quantum information science to determine qubit fidelity and to characterize individual qubit gates. It is also an excellent example of a quantum experiment with advanced requirements on the control hardware and software. For an RB experiment, we apply random sequences of...

The Next Generation of Signal Generators - SHFSG Launch Event


SHFSG Launch Event

On April 29th, Jan Benhelm, Mark Kasperczyk and I welcomed a crowd of customers to the interactive online event introducing Zurich Instruments’ newest product, the SHFSG Signal Generator. Our aim was to present multiple perspectives on the launch of this powerful instrument. Jan provided an overview of Zurich Instruments’ quantum...

Comparison of Liquid Conductivity Probes


EIS Probe

In a previous blog post, we described how to use the MFIA Impedance Analyzer to measure the electrochemical impedance spectrum (EIS) of a liquid sample and to derive the conductivity with EIS modeling. The post presented a 5-element equivalent circuit model, which required a relatively deep understanding of electrochemistry. However...

Customized Output Data Format for Impedance Sweeps


Data Format

This short blog post shows you how to customize the exported data of your impedance sweeps on the MFIA and MFLI with MF-IA option. The Sweeper module of LabOne® is an excellent tool to sweep frequency, amplitude or bias offset, and measure multiple parameters as a function of the swept parameter.

Capturing Transients with the Zurich Instruments Toolkit


MFIA configuration

In many applications, Zurich Instruments' lock-in amplifiers and impedance analyzers are integrated into a larger measurement system. Relying on an application programming interface (API) to obtain necessary information from the instruments is of great importance in such cases...

Come Effettuare Misure DLTS con lo MFIA


Voltage and Capacitance in Plotter

Questo articolo illustra come produrre un'onda quadra in tensione ed acquisire i conseguenti transitori di capacità, in una scala temporale molto corta (ad esempio 20 us), per effettuare misure di tipo "deep level transient spectroscopy" (DLTS). DLTS è una tecnica potente e comunemente usata per investigare sia la concentrazione che...

Practical Active Qubit Reset


Active Qubit Reset Setup

When working with qubits, it’s essential to have a reliable state preparation. The easiest method for superconductive qubits is to passively wait for the qubit to decay into its ground state, but it’s slow and has poor fidelity. Active qubit reset decreases considerably the initialization time, while greatly increasing the...

Probing Local Magnetic Field Patterns - Q&A


Probing Local Magentic Field Patterns

For this webinar we teamed up with Prof. Martino Poggio, whose work focuses on understanding the physics of materials and phenomena that is strongly dependent on the local conditions, be it by impurities or through the design through local probing of magnetic fields coming from currents and magnetization. Several notable...

Content Review – Lock-in Detection


Lock-in Tab

Test and measurement tasks often carry the challenge that sought for signals are buried in noise. The fundamental use of a lock-in amplifier is to recover these signals, but modern digital lock-in amplifiers can do much more than this. To help you take full advantage of the capabilities of your...

Automating IQ Mixer Calibration on the HDIQ


LO Leakage

As a crucial step in the bring-up of superconducting experiments, IQ mixer calibration normally requires multiple instruments from different parties and manual cabling work. This blog post describes how to use the Zurich Instruments HDIQ, HDAWG and UHFQA (or other UHF instruments) to automate IQ mixer calibration and: Simplify the...

Sensing Finger Movements with Impedance Measurements



Smart clothes, wearables and biosensors do not sound as futuristic as they used to. The development in this field of science and engineering is rapid and it is no longer a niche – as seen in the first or even second generation of such products hitting the market. Although there...

Fast Frequency Sweeps for Impedance Measurements


Sweeper Trace

When characterizing a device or material as a function of frequency, the resulting spectrum may change with time as the environment or material itself evolves. This time evolution can be captured by taking sequential frequency sweeps with the LabOne Sweeper module on the MFIA or the MFLI. Each sweep requires...

Compensating Cables for Accurate Impedance Measurements


MFITF attached to MFIA

Measuring impedance accurately can be a challenge, especially when the device or material under test is located some distance away from the impedance analyzer at the end of cables. The phase delay and parasitic impedance of the cables can significantly reduce the accuracy of a measurement. This blog post seeks...

Proximity Sensors – Inductive or Capacitive?


Proximity Measurement

A proximity sensor is a sensor that detects nearby objects without physical contact [1]. They are commonly used, in applications ranging from production lines to modern mobile devices, mainly thanks to their non-contact configuration and the accompanying long lifetime. The working principle is simple...
