The ETH Zurich - PSI Quantum Computing Hub

Take a peek at the Superconducting Quantum Circuits Lab of the ETH Zürich - PSI Paul Scherrer Institut Quantum Computing Hub.

During the last three years we have equipped this lab from scratch. It now houses three setups for the study of quantum information processing with superconducting circuits. The work is supported through a number of projects. These include an IARPA - program on Entangled Logical Qubits (ELQ), an Innosuisse technology transfer project, and a Staatssekretariat für Bildung, Forschung und Innovation SBFI program on Quantum Information Science, all of which are executed in collaboration with Zurich Instruments , a company which started as a spin-off of 瑞士苏黎世联邦理工学院 and is now part of the Rohde & Schwarz family.

The lab has three experimental setups. We have named the setups after the Swiss glaciers Otemma, Allalin, and Silvretta . The setups either operate a number of samples simultaneously in four- or six-port multi-sample mounts for device and process testing, in 16- or 48-port sample mounts to test devices with five to 20 qubits, or a 128-port sample mount which currently can operate up to 43 superconducting qubits in a single package.

The mechanical mounts of each cryogenic system have been designed and custom-made by our lab.

The control electronics are focused on equipment from Zurich Instruments who we collaborate with on a range of projects.

The infrastructure needed to operate the cryogenic equipment is installed in a hall located just behind the cryogenic equipment. We made an effort to screen the sensitive equipment used for operating the quantum processors from the infrastructure through electromagnetic shields. We also made an effort to install the equipment in a space-efficient and clean arrangement.

The cryogenic setups are equipped with our lab's own custom-made sample mounts ...

... and our own custom-designed and made wiring solutions.

This is one of our setups during installation.

In the lab our students and researchers operate the experiments from a control room which is separated from the experimental equipment by a set of glass walls which allow for good visual access while keeping the noise and heat of the equipment away from the researchers.

Our Superconducting Quantum Circuits lab at the Quantum Computing Hub at PSI Paul Scherrer Institut is run jointly by a team of students, postdocs and staff together with the Quantum Device Lab at 瑞士苏黎世联邦理工学院 .
