Weak quantum questions

The researchers verified that a series of two weak quantum measuments can lead to restore the original state. The second measurement effectively undoes the effect of the first one. The picture shows the heart of the setup, where the qubits were generated and handled. Picture: Erik Lucero, Martinis Group.
