Quantum Sensing

Nuclear Magnetic Resonance (NMR) Spectroscopy is a technique used for determining the structure of organic compounds. Traditionally an LO, mixer (upconverter), an AWG and an RF receiver or lock-in amplifier would be used to achieve the needed measurement.

Using the Proteus Arbitrary waveform Transceiver allows a simpler, more accurate, and cost-effective instrument.

Achieve deterministic, ultra-low latency timing essential for Quantum Computing by utilizing the Proteus's innovative memory architecture. This unique system combines large DRAM for waveform storage with very fast, on-FPGA static RAM to ensure pulse switching speeds and deterministic timing necessary for real-time pulse duration and timing adjustments.

Streamline your multi-qubit experiments by leveraging Direct-to-RF Waveform Generation with the multi-channel Proteus unit. This approach eliminates the complex calibration and external IQ modulation required by traditional setups, allowing you to easily generate up to 22 channels of phase-coherent, direct-to-microwave control pulses (e.g., 4 GHz pulses).

There are several considerations one must take into account when deciding to acquire a new signal amplifier. The following tutorial will address the topics which are most related to Tabor’s line of signal amplifiers as well and will provide tips for selecting the most suitable amplifier for your application. It will also explain how each of the topics would influence the amplifier’s performance.

PXI or PCI eXtension for Instruments was introduced to the market in 1997, as an effort reduce the overhead of connectivity standards such as GP-IB and LAN eXtensions for Instruments (LXI). Fundamentally the instrument directly becomes part of the computer’s architecture much like an addition of an advanced video processor, or an extra processing unit such as a GPU

The Tabor Proteus family of Arbitrary Waveform Generators (AWG) and Arbitrary Waveform Transceivers (AWT) are programmed using the industry standard instrument programming language SCPI. In this tutorial we go over how to connect to an instrument, create a waveform and digitize a signal.

A quick look at some of the most common signal generators used to produce waveforms, frequencies, radio frequencies (RF), digital patterns, etc.

10 Tips for using an Arbitrary Waveform Generator (AWG) in Quantum Experiment control and measurement applications.

In this article, we’ll review the Quantum setup architecture, in regards to arbitrary waveform generators, and the fundamental role they have in the process of controlling quantum bits, qubit measurement, and analysis.

We will review and explain the fundamentals of wave propagation, impendence matching and transmission, passive frequency translation, and how the properties of nonlinear frequency summation devices such as mixers - can help modify the signals' frequency. We’ll cover Modulation and the process of encoding information on to generated frequency – and we will look at AM and Phase Modulation and how they are combined in a vector modulator. We will look at both analog and digital implementations of modulation, and Signal Analysis.

Real-World high-speed arbitrary waveform generators and digitizers can't implement a perfect flat frequency response with a linear phase (fixed delay) behavior over the full bandwidth. It is virtually impossible to reproduce exactly the same response for all the instruments and even for all the different channels in the same device. Some applications can cope with such limitations. Others, such as qubit control or wireless test, can't. The solutions are calibration and corrections.

Nuclear Magnetic Resonance (NMR) Spectroscopy is a technique used for determining the structure of organic compounds. Some nuclei possess a magnetic moment. In a strong magnetic field, the magnetic moment of each nucleus will align with the magnetic field of the magnet. If you apply resonant RF energy it will cause the nuclei to jump to a higher-energy state and the nuclei magnetic moments will rotate or process

This white paper introduces the Effective Number of Bits (ENoB) concept and its impact on the real performance of AWGs in different applications. The ENoB specification is made of multiple parameters and the importance of each greatly depends on the signal being generated and the way it will be applied to the system under test.

The IEEE 1658-2011 standard covers some test methodologies to obtain the SINAD parameter, so the ENoB specification can be directly calculated. One of the methods is based on acquiring the test signal (a sinewave) being generated by the DAC with a suitable ADC. Examining the signal in the frequency domain or breaking the signal into its constituent parts using an FFT (Fast Fourier Transform) allows us to identify and evaluate the signal.
