Bell-state stabilization with real-time feedback is a key milestone for the implementation of surface code [1], which is one of the most promising quantum error correction codes for building large-scale quantum computers [2]. Fundamental requirements for realizing this code are high fidelity and rapid readout of qubits, high fidelity gate...
When working with qubits, it’s essential to have a reliable state preparation. The easiest method for superconducting 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...
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...
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...
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...
