In this episode of Nick Knows, he presents a technique called dynamical decoupling, which in its simplest form “refocuses” the dephasing noise experienced by qubits while they are idle. In general, dynamical decoupling can be used to modify the effective noise seen by qubits as a function of frequency. While it is still a topic of active research, it has successfully been utilized for improving Quantum Volume and quantum simulations.
