The Quantum Device Lab is engaged in a number of individual and collaborative projects funded by the European Commission and the Swiss National Science foundation. An overview of these projects is presented on this webpage.

Ongoing Projects

State Secretariat for Education, Research and Innovation

The Quantum Device Lab aims at expanding the size and performance of its quantum information processing hardware in a modular approach. Starting with small modules, the team will demonstrate inter-module and intra-module operation. Instrumentation and software to characterize efficiently and operate a modular quantum computer will be developed. The lab will integrate such modules, containing up to several tens of qubits, in a 3D architecture using flip-chip technology with bump bonds.

The Quantum Device Lab at ETH Zurich and the Superconducting Quantum Circuits Group at the ETHZ-PSI Quantum Computing Hub, in collaboration with Zurich Instruments, will develop an integrated software/hardware system, enabling scalable quantum computing experiments with real-time feedback for large-scale quantum error correction and new applications such as initial state preparation and verification of quantum algorithms.

Swiss National Science Foundation (SNSF), NCCR

The NCCR SPIN aims to make a major contribution to research into and the development of quantum computers and create the basis for a new information-processing technology. The NCCR’s objective is to develop small, fast, scalable silicon-based qubits. It will also generate important findings on software and algorithm development, error correction and the architecture of future quantum computers.

Completed Projects

Programme: H2020-FETOPEN-2018-2020 / H2020-FETOPEN-2018-2019-2020-01

Superconducting quantum circuits are one of the most promising platforms for realizing large-scale quantum computing devices, where in the near future a coherent integration of 100-1000 quantum bits (qubits) is feasible. However, the required temperatures of only a few mK currently restrict quantum operations to qubits that are located within a single, heavily shielded dilution refrigerator. This imposes a serious constraint on the realization of even larger quantum processors or the implementation of local- and wide-area quantum networks based on this technology.

Programme: Swiss National Science Foundation (SNSF)

In this project we will develop building blocks of a fully deterministic quantum photonics framework in the microwave frequency domain. By exploiting the unique properties of superconducting circuits, we focus on the realization of (i) deterministic photon-photon entangling gates , (ii) sources of cluster states, and (iii)  quantum memories to absorb, store and relieve photons with a controllable time delay.
