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. Using a trapped-ion quantum processor, the team successfully ran Grover's quantum search algorithm on three logical qubits.

Welcome Beatrice! Beatrice completed her Bachelor’s degree at the University of Padua and is currently pursuing her Master's degree in Physics of Condensed Matter at the same institution. For her Master's thesis, she has joined our Barium Lab, where she will work on in-sequence operations on Barium ions with the aim of achieving resolved sideband cooling on the S_1/2–D_3/2 transition.

Welcome back Lorenzo! Lorenzo completed his Bachelor's degree at the Alma Mater University of Bologna, and his Master's degree at the University of Padua. He conducted his Master's thesis at UIBK on RF electrodes optimization and effects of RF technical noise in surface electrode ion traps. Lorenzo will now join the Cryo team to work on scalable architectures for trapped ion quantum computing.

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.

Thomas Lafenthaler completed his Masters on the topic of Ionisation and state preparation for single ion experiments. Congratulations, Thomas!

Marco Lucibello completed both his Bachelor’s and Master’s degrees in Physics at Roma Tre University, Italy. For his Master’s thesis project, he joined the group of Francesca Ferlaino, where he worked on a setup for stray electric field compensation to improve the coherence time of erbium Rydberg atoms in optical tweezers. Marco has now started his PhD in the Quantum Simulations team.
