Visualizing Kraus operators for dephasing noise during application of the $\sqrt{\mathrm{SWAP}}$ quantum gate

Nicolas André da Costa Morazotti, Reginaldo de Jesus Napolitano

We consider the case of a $\sqrt{\mathrm{SWAP}}$ quantum gate and its optimized entangling action, via continuous dynamical decoupling, in the presence of dephasing noise. We illus…
