The main milestone of subproject-2 is the theoretical development of operation and control protocols for quantum sensors based on color centers in naodiamonds valid in detection regimes of low frequency and low magnetic field. Despite the high interest in these technologies, these detection regimes have so far not been fully explored. The low frequency, low magnetic field regime is crucial for the distinction of free radicals in an experimental context, in particular the detection of the so-called J coupling between nuclear spins. Beyond the ideal protocol of operation, it is necessary to verify its robustness and stability in noisy contexts of the type that can be found in realistic experiments with biological samples. Sophisticated classical simulation techniques of open quantum systems will be developed and adapted for realistic representations of the nanodiamond environment and the samples. Different degrees of complexity will be considered, and special emphasis will be placed on the use of our own tool known as transfer tensors. This will allow the establishment of action protocols and design principles for the first laboratory of these characteristics in Spain. The ability of this infrastructure to detect and distinguish free radicals depends crucially on the theoretical ability to control and interpret data, among other laboratory support tasks.
