    Quantum vortices confirm superfluidity in supersolid
    05.11.2024
    than 50 years ago, physicists predicted that quantum mechanics allows such a state, where a collection of indistinguishable particles can simultaneously exhibit seemingly contradictory properties. “It is a bit like Schrödinger's cat, which is both alive and dead, a supersolid is both rigid and liquid,” explains Francesca Ferlaino from the Department of Experimental Physics at the University of Innsbruck and the Institute of Quantum Optics and Quantum Information (IQOQI) of ...

    Quantum times: when did the cuckoo sing?
    29.05.2020
    We are used to the fact that events are sharply localised in time. In a cuckoo clock, the cuckoo always calls at a precise time. Everybody looking at the clock would agree on this. However, a team of physicists led by Caslav Brukner from the University of Vienna and the Austrian Academy of Sciences showed that, when quantum mechanics and Einstein’s general relativity are combined, this might no longer be the case. When time “goes quantum” the temporal localisability of events becomes relative. In quantum times, the cuckoo can call at a precise time according to one observer, but some other observers might be totally uncertain about the time when it sings.

    Quantum teleportation
    05.10.1998
    In 1998, entanglement between one pair of particles was transferred to another pair of particles for the first time - a scientific breakthrough that was also referred to when Anton Zeilinger was awarded the Nobel Prize in Physics in 2022.

    Quantum simulation: Measurement of entanglement made easier
    24.06.2021
    individual measurements are necessary. The method used to read out the quantum state of a quantum simulator is called quantum state tomography. "Each measurement provides a 'cross-sectional image' of the quantum state. You then put these cross-sectional images together to form the complete quantum state," explains theoretical physicist Christian Kokail from Peter Zoller's team at the Institute of Quantum Optics and Quantum Information at the Austrian Academy of Sciences and ...

    Quantum revolution takes a leap forward
    06.02.2020
    bit, the most common quantum information is called qubit . The processing of qubits relies on a few fundamental operations called quantum gates. For some systems, the implementation of such operations is already well established. Quantum technology has taken major strides recently, with a quantum computer achieving quantum supremacy and for the first time, surpassing the performance of conventional devices, and with the arrival of satellite-based quantum cryptography. Quantu ...

    Quantum physicists develop new method for cooling nanoparticles
    05.04.2019
    Such isolated particles not only display unprecedented quality as sensors, but can also be used to investigate basic processes of engines at the nanoscale or quantum phenomena with large dimensions. An essential part of this research is to gain unrestricted control over the movement of the particle, ideally in a regime where the laws of quantum physics dictate its behavior. Earlier attempts to achieve this either modulated the optical tweezers themselves or exposed the ...
