This is not the RCS problem or indeed anything from number theory.
The announcement is about an algorithm which they are calling Quantum Echoes, where you set up the experiment, perturb one of the qbits and observe the “echoes” through the rest of the system.
They use it to replicate a classical experiment in chemistry done using nuclear magnetic resonance imaging. They say they are able to reproduce the results of that conventional experiment and gather additional data which is unavailable via conventional means.
