An ERC Advanced Grant was awarded to Andreas Wallraff by the European Research Council (ERC) for the project "Superconducting Quantum Networks". The newly received Grant follows up the ERC Starting Grant that he won in 2009.

We demonstrated exchange interactions, superradiant states and subradiant states for two qubits placed two centimeters apart in an open one-dimensional space, as published in Science online.

The Baugarten Stiftung has facilitated a strong start to the “Quantum Engineering Initiative”. This pioneering commitment to the ETH Zürich Foundation enables two pieces of high-tech laboratory equipment to be acquired, representing the next vital step in the production of scalable basic elements in quantum physics systems.

ETH President Ralph Eichler's final Lokaltermin event focused on a topic close to his heart: together with five other experts from ETH Zurich, he gave representatives from the worlds of business, politics and science an insight into the unusual world of quantum physics and explained how it may be used commercially in the future.

We have implemented a scheme for generating single microwave photons with a tunable shape in superconducting circuits. The experiment describing the fully microwave-controlled shaping process is published in Phys. Rev. X .

We realized a two-spin "Gedankenexperiment" suggested by Dicke in 1954 using a system of two individually controllable superconducting qubits weakly coupled to a fast decaying microwave cavity. We demonstrate superradiance of two emitters both in time and by reconstructing the density matrix of the emitted field. The results of this work are published in Nature Communications.

Quantum simulations are expected to vastly outperform classical simulations when modeling the dynamics of interacting spin systems. Researchers have used a digital quantum simulation to show that spin dynamics can be studied and predicted, which lays the groundwork for applications in quantum magnetism and strongly correlated systems.

By employing a fully controlled cavity quantum electrodynamic system made of superconducting circuits, we experimentally create matrix product states, a class of states that has proven to be extremely powerful as a variational ansatz for numerical simulations. We create 1000 such quantum states and efficiently probe their correlation properties to determine an approximation to the ground state of a model describing a gas of interacting quantum particles. Having physical access to the simulated ground-state wave functions enables us to also probe higher-order correlation functions beyond measuring the ground-state energy. The experimental data are in good agreement with the exact solution over a wide range of interaction strengths of the model.

What sort of options do high-school students have for their future? How does work in basic research look like? What do scientists explore in the Quantum Device Lab at ETH Zurich? Teachers of the canton school Zurich Oberland (KZO) wanted to know.
