The Zurich Instruments Quantum Computing Control System provides reliable and precise timing synchronization out of the box. But what does reliable synchronization really mean? Here, we show results from two experiments that put the synchronization stability to a hard test. First, we synchronize two SHFQC Qubit Controllers across 52 meters synchronization distance to conduct a photon pitch-and-catch experiment on a real quantum chip. Second, we assess the long-term stability of such long-distance synchronization links for a full 14-day period.

Real-time feedback control can often speed up quantum experiments, increase fidelity, or enable new methods. One example is adaptive sensing and characterization, which uses feedback to minimize the number of measurements needed to estimate a given quantity. Our customers in the group of Prof. Cristian Bonato at Heriot-Watt University (Edinburgh, Scotland) have recently demonstrated this method on an NV-center based spin qubit and achieved an increase in speed by up to an order of magnitude compared to non-adaptive approaches in the estimation of qubit decoherence timescales.

An arbitrary waveform generator (AWG) can generate pulses with a timing resolution much finer than its sampling period. Users are often unaware of this capability, yet it enables highly precise timing control in application use cases such as NV center dynamical decoupling, flux pulse width control, AWG channel deskew, and IQ mixer calibration...

Were you ever curious about how the double-superheterodyne frequency conversion compares with IQ mixing when tested on real qubits? This blog post introduces such a comparison published in a recent preprint paper by the ETH QuDev lab. One of its main results hints at double-superheterodyne enabling a higher gate fidelity and lower state leakage rate than a standard IQ mixing approach!

Does your application require multiple AWG channels with precise and stable timing synchronization? In this blog post, we will show how to achieve this with the HDAWG Arbitrary Waveform Generator for setup sizes ranging from few channels up to 144. We demonstrate 3 methods suitable for different use cases.

Lock-in amplifiers are extremely versatile and used in a plethora of applications ranging from optics and photonics, nanotechnology, spm, and sensing, among others. In this blog, you will learn how to use the MFLI Lock-in Amplifier to carefully assess the experimental conditions and prepare your setup for the best measurement outcome.

Getting your measurements up and running as fast as possible is a priority at Zurich Instruments. Together with one of our Application Scientists, researchers at the ETH Zurich - Paul Scherrer Institute (PSI) Quantum Computing Hub were able to install the SHFQC Qubit Controller and perform qubit spectroscopy, Ramsey, and Rabi measurements on 5 qubits in parallel in half a day. The ability of our instruments to perform fast frequency sweeping was at the heart of the fast qubit tune-up procedures. Learn more in this blog post.

Isn't the best way to learn about experimental methods by exchange with other experts in the field? In this spirit, we hosted the Quantum Technology User Meeting together with Rohde & Schwarz from 13.-15.06.2022 in Munich. If you could not join in person, take a look at this blog post - and stay tuned for the next edition.

When operating qubits, speed and high system utilization are key to achieving rapid progress. In this blog post, you’ll find a collection of five important tips to optimize the throughput of your Zurich Instruments Quantum Computing Control System (QCCS) and perform measurements faster than ever!

It all starts with a few qubits: a masterfully engineered few-qubit system forms the groundwork for advances in large-scale quantum computers. This blog post gives you our 5 top reasons why you should base your few-qubit setup on the Zurich Instruments SHFQC Qubit Controller.

In this webinar, we covered the material properties that are most important to consider when developing qubits with longer coherence times and looked into how to characterize these materials accurately and efficiently. By focusing on the fundamental properties of the materials, simpler fabrication methods and experimental setups can be used...
