Noise Spectrum Analysis at the NV center in diamond — •Konstantin Schukraft, Florian Rempp, Fedor Jelezko, and Jörg Wrachtrup — 3. Physikalisches Institut, Uni Stuttgart

Being able to extend the coherence time of quantum systems is very important not only for quantum computers, but also for high precision metrology applications. To efficiently decouple a system from its environment one needs to know that environment, characterised by the noise spectrum it generates. Since the noise spectrum isn't accessible directly in our case, we retrieve it via echo measurements. These are conducted with the NV centers electron spin; not only already an important measurement tool for the aforementioned high precision measurements, but also a candidate for high/room temperature quantum computers.
