Entanglement characterization touches a new milestone

Entanglement is the backbone of quantum information science. Quantum computers and simulators can outperform classical calculations when simulating complex many-body quantum states. In modern times, characterizing entanglement in quantum simulations is a tricky task. Due to the fragile nature of entanglement and the exponentially increasing number of measurements required for characterizing entanglement with the system sizes, experimental techniques and analysis methods need to be upgraded to more sample-efficient methods. Here, theoretical ideas originally formulated for conformal field theories come into play. These ideas state that a mixed state, segregated from continuum spatial and temporal systems, can be represented by a Gibbs ensemble. The original concept was formulated for lattice models and has now been tested on a trapped ion quantum simulator.

Welcome Florian Kofler

Welcome Florian! Florian joined the AQTION team for his Master's project, where he will implement modulated Mølmer–Sørensen gates to improve the robustness of the gate against fluctuations of the experimental parameters.


Welcome Fabitha Kodakkat

Welcome Fabitha! Fabitha joined the Distributed Quantum Systems Group as a postdoc. She earned her doctoral degree at IIT Madras, India and her previous postdoctoral research focused on quantum sensing at IIT Bombay, India. Her project in here Innsbruck involves investigating light-matter entanglement across deployed optical fiber links.


Welcome René Nardi

Welcome René! René joined the QCosmo team for his Master's project, where he will build a time-of-flight mass spectrometer to selectively ionize and load different molecular species into a paul trap.


Welcome Elyas Mattivi

Welcome Elyas! Elyas joined the QCosmo team for his Master's project, where he will set up and amplify a telecom-wavelength frequency comb for the manipulation of the rotational states of trapped molecular ions.


Welcome Mariano Monsalve

Welcome Mariano! Mariano worked during his Master's thesis with Prof. Tim Schroeder from the Humboldt University zu Berlin in the application of single qubit gates towards the generation of photonic cluster states with Tin vacancy defect centers in diamond. In Innsbruck he is joining the QCosmo team, working on molecular quantum systems.
