Innsbruck physicists have presented a new architecture for improved quantum control of microwave resonators. In a recently published study, they show how a superconducting fluxonium qubit can be selectively coupled and decoupled with a microwave resonator and without additional components. This makes potentially longer storage times possible.

Quantum states can only be prepared and observed under highly controlled conditions. A research team from Innsbruck, Austria, has now succeeded in creating so-called hot Schrödinger cat states in a superconducting microwave resonator. The study, recently published in Science Advances, shows that quantum phenomena can also be observed and used in less perfect, warmer conditions.

Quantum simulators are a completely new tool for research: quantum physics is studied by other kinds of quantum physics. Research teams from Innsbruck and Vienna are developing a new method that will allow this new technology to be reliably verified.

The University of Concepción in Chile has awarded a honorary doctorate to quantum physicist Peter Zoller for his scientific achievements in quantum optics and quantum information. The honor was also in recognition of his long-standing ties with the Latin American university.
