Keeping a spin qubit alive in natural silicon: Comparing optimal working points and dynamical decoupling
Keeping a spin qubit alive in natural silicon: Comparing optimal working points and dynamical decoupling
There are two distinct techniques of proven effectiveness for extending the coherence lifetime of spin qubits in environments of other spins. One is dynamical decoupling, whereby the qubit is subjected to a carefully timed sequence of control pulses; the other is tuning the qubit towards ``optimal working points'' (OWPs), which …
