Qubit and Resonator Spectroscopy at the Speed Limit: Your Measurements. Faster.

23.06.2022

Qubit Spectroscopy

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.

Practical Active Qubit Reset

05.03.2021

Active Qubit Reset Setup

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...
