New method prevents quantum computers from crashing

New method prevents quantum computers from crashing Copyright: Harald Ritsch

Quantum information is fragile, which is why quantum computers must be able to correct errors. But what if whole qubits are lost? In collaboration with colleagues at the University of Innsbruck and University of Bologna, we developed and experimentally implemented a method published in the journal Nature that allows quantum computers to keep going even if they lose some qubits along the way. We invite you to also have a look at the press release!

Lorenzo completed his PhD at the University of Hannover, Germany, where he investigated quantum link models and topological phases in cold atom systems.

At Aachen he is joining the EU Quantum Technology Flagship AQTION project, where he hopes to deploy his expertise in AMO physics and the study of strongly correlated systems to contribute to the development and applications for Europe’s first compact trapped-ion quantum computer demonstrator.

Lorenzo started his work from 01st July 2020.


Welcome Sascha Heußen
