A roadmap for the future direction of quantum simulation has been set out in Nature this week. An international team of researchers, among them Innsbruck physicists Peter Zoller and Christian Kokail explore near and medium-term possibilities for quantum simulation on analogue and digital platforms.

For decades computers have been synonymous with binary information – zeros and ones. Now a team at the University of Innsbruck, Austria, realized a quantum computer that breaks out of this paradigm and unlocks additional computational resources, hidden in almost all of today’s quantum devices.

Today, Rainer Blatt and Peter Zoller have been awarded the Austrian Cross of Honor for Science and Art, 1st Class. With their groundbreaking research, the two scientists are considered pioneers in their field and have laid essential foundations for the development of new quantum technologies such as quantum computers.

For quantum computers to be useful in practice, errors must be detected and corrected. In Innsbruck, Austria, a team of experimental physicists has now implemented a universal set of computational operations on fault-tolerant quantum bits for the first time, demonstrating how an algorithm can be programmed on a quantum computer so that errors do not spoil the result.

Nearly circular 2D supersolid in a round trap

In a new study, investigations led by Francesca Ferlaino and Russell Bisset show how to cool an atomic gas into a supersolid with a circular, 2D shape. The method will allow researchers to further study these exotic states of matter and search for features such as turbulent vortices.
