A Fast and Scalable Approach to Controlling 100 Qubits and More - Q&A

02.09.2020

On August 20, we talked about our fast and scalable approach to controlling 100 qubits and more. The webinar was recorded and is available on demand here . In the first part of the webinar, we covered our fast approach and explained how to get a handle on the complexity...

Multiplexed Readout of Superconducting Qubits with the UHFQA

15.01.2020

Frequency-multiplexed readout of qubits is at the heart of superconducting quantum processors and an essential step for scalable architectures. The UHFQA Quantum Analyzer is specifically tailored for this challenge and brings the latest technology to work in your lab - using high level API. In this blog post we demonstrate...

AWG Precompensation for High-Fidelity CZ Gates in Transmon Qubits

02.11.2019

High quantum gate fidelity is essential for all quantum hardware platforms. Temporal sensitivity to flux noise and flux pulse distortion can pose major limitations to achieving high fidelity with repeatable two-qubit gates in transmon qubits. In a recent publication, Rol and collaborators demonstrated a fast (40 ns), low-leakage (0.1%), high-fidelity...

Are Your Parametric Two-Qubit Gates Limited by the Driving AWG?

13.09.2019

If you are using the Zurich Instruments HDAWG, the answer is no. Let's see why. Parametrically modulated superconducting qubit gates (parametric gates) are usually accomplished by RF-modulation – typically several hundred MHz – of the flux through a mediating coupler element or qubit. Usually, many dBm of signal power are...
