Not all quantum measurements are created equal
Proving that one quantum measurement is more powerful than another has long been difficult. Physicists from Heinrich Heine University Düsseldorf, Lund University, and the University of Innsbruck have now developed and demonstrated a simple technique to certify that a certain class of measurements has properties that cannot be mimicked by simpler means.
Quantum computing without interruptions
Mid-circuit measurements are one of the biggest practical hurdles in quantum error correction on encoded qubits. Researchers in Innsbruck and Aachen have now proposed and experimentally demonstrated that a universal fault-tolerant quantum algorithm can be executed without such measurements.
Debugging a quantum processor
Researchers at the University of Innsbruck, together with partners from Sydney and Waterloo, have presented a new diagnostic method for quantum computers. It makes errors in individual quantum bits visible during logical calculation and evaluates them. The new method was demonstrated on an ion trap quantum processor in Innsbruck. It can be used to identify critical error sources —a key to developing more robust, fault-tolerant quantum processors.
Noise-proof quantum sensors
Researchers at the University of Innsbruck have shown that quantum sensors can remain highly accurate even in extremely noisy conditions. It’s the first experimental realization of a powerful quantum sensing protocol, outperforming all comparable classical strategies—even under overwhelming noise.
Welcome Jakob Tilg
Welcome Jakob! Jakob earned his bachelor's degree in Innsbruck. In his bachelor's thesis supervised by Thomas Monz, he engaged in quantum error correction. Now he is pursuing a master's degree in physics and a extension programme in computer science here in Innsbruck. For his master’s thesis, he joined the Hyperion team and will work on new techniques for entangling gate characterization.
Welcome Simone Repic
Welcome Simone! Simone is currently pursuing his Master's degree in Physics (Quantum Science and Technology curriculum) at the University of Trieste, where he also completed his Bachelor’s degree with a thesis about Quantum Key Distribution. He is now carrying out his Master's thesis within the QCosmo group with the goal of designing and building a component for the cryogenic experimental setup for quantum logic spectroscopy with trapped molecular ions.
