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.
A team led by Francesca Ferlaino has set a new milestone in atomic physics by trapping individual erbium atoms in optical tweezers for the first time. Taking advantage of erbium’s complex electronic structure, which opens up new degrees of freedom and possibilities, this advancement opens the door to a range of innovative experiments in quantum science.
