Exploiting ionization dynamics in the nitrogen vacancy center for rapid, high-contrast spin and charge state initialization

Adam Gali, Daniel Wirtitsch, Fedor Jelezko, Georg Wachter, Michael Trupke, Michal Gulka, Milos Nesladek, Sarah Reisenbauer, Viktor Iv\'ady

Charge state transitions in NV centers can be turned into a tool that raises spin readout contrast by 17 percent and cuts initialization error by more than half.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We observe a relative improvement of the readout contrast by 17 %, and infer a reduction of the initialization error of more than 50 %. ... a measurement speedup by a factor of >1.5 is extracted

C2weakest assumption

That the charge state purification by strong laser pulse followed by weak illumination reliably leads to higher spin polarization without introducing additional noise or decoherence in practical sensing sequences.

C3one line summary

A two-step optical protocol using charge state dynamics boosts NV center spin contrast by 17% and reduces initialization error by over 50%.
