PhD and Postdoc positions are available in the Research Group “Quantum Information and Quantum Many-Body Physics”, led by Norbert Schuch, at the University of Vienna. Topics of interest cover the whole range from quantum information […]
Dark matter makes up about 27% of the matter and energy budget in the universe, but scientists do not know much about it. They do know that it is cold, meaning that the particles that […]
Quantum 6, 876 (2022). https://doi.org/10.22331/q-2022-12-13-876 Many quantum algorithms for numerical linear algebra assume black-box access to a block-encoding of the matrix of interest, which is a strong assumption when the matrix is not sparse. Kernel […]
Quantum 6, 875 (2022). https://doi.org/10.22331/q-2022-12-13-875 Here we argue that the probability that a given source produces exactly a single photon is a natural quantity to benchmark single-photon sources as it certifies the absence of multi-photon […]
Quantum 6, 874 (2022). https://doi.org/10.22331/q-2022-12-13-874 We introduce a hybrid quantum-classical variational algorithm to simulate ground-state phase diagrams of frustrated quantum spin models in the thermodynamic limit. The method is based on a cluster-Gutzwiller ansatz where […]
Many years ago, I learned to program on an old Symbolics Lisp Machine. The operating system had a built-in command spelled “DWIM,” short for “Do What I Mean.” If I typed a command and got […]
Insider Brief Researchers demonstrate another quantum mechanical effect in superconductors – the photon assisted coherent quantum phase slip effect in a very thin superconducting nanowire. The effect is revealed as the formation of current steps […]
This is an early announcement so the official application web page is missing. Please enquire at the PI directly using the e-mail address given below. We are looking for a Postdoctoral researcher at the Department […]
Insider View The Quantum Insider (TQI) announced the release of significant new features on its market intelligence platform. TQI’s engineers have designed the new features to offer unparalleled insights and analysis for investors, quantum stakeholders […]
Insider Brief Aalto University have developed optical chirality logic gates that may be able to operate about a million times faster than existing technologies. The new approach uses circularly polarized light as the input signal. […]
