New method prevents quantum computers crash

Quantum information is fragile, which is why quantum computers must also be able to correct errors. But what if whole qubits are lost? Researchers at Forschungszentrum Jülich and RWTH Aachen University, in collaboration with Universities of Innsbruck and Bologna, are presenting a method in the journal Nature that allows quantum computers to keep going even if they lose some qubits along the way.
