Our spatial sense doesn’t extend beyond the familiar three dimensions, but that doesn’t stop scientists from playing with whatever lies beyond. Click to rate this post! [Total: 0 Average: 0]You have already voted for this […]
Paderborn University is a high-performance and internationally oriented university with approximately 20,000 students. Within interdisciplinary teams, we undertake forward-looking research, design innovative teaching concepts and actively transfer knowledge into society. As an important research and […]

The discovery of cuprate high-temperature superconductors in 1986 impacted science and technology considerably and continues to fascinate the communities of condensed matter physics and material sciences because they host the highest ambient-pressure superconducting transition temperature […]

This week has been a big week for Colorado’s quantum community, as delegates from the Government of Finland visited the snowy state to celebrate the beginning of several quantum research and quantum technology partnerships between […]
Quantum 6, 659 (2022). https://doi.org/10.22331/q-2022-02-21-659 Spekkens has introduced an $textit{epistemically restricted classical theory}$ of discrete systems, based on discrete phase space. The theory manifests a number of quantum-like properties but cannot fully imitate quantum theory […]
Quantum 6, 658 (2022). https://doi.org/10.22331/q-2022-02-21-658 We consider online strategies for discriminating between symmetric pure states with zero error when $n$ copies of the states are provided. Optimized online strategies involve local, possibly adaptive measurements on […]
Quantum 6, 657 (2022). https://doi.org/10.22331/q-2022-02-21-657 We propose a method to reliably and efficiently extract the fidelity of many-qubit quantum circuits composed of continuously parametrized two-qubit gates called matchgates. This method, which we call $textit{matchgate benchmarking}$, […]
Quantum 6, 656 (2022). https://doi.org/10.22331/q-2022-02-21-656 In this work, we characterize the amount of steerability present in quantum theory by connecting the maximal violation of a steering inequality to an inclusion problem of free spectrahedra. In […]
