Goals of the ICRC TRR 160

The overarching goal of the ICRC requires elaboration of prospective material concepts and sophisticated manipulation tools, inspired by recent progress in obtaining material of highest purity, by advancing spectroscopic techniques to reach ultimate sensitivity and by developing elaborate models for spins interacting within a many-body environment. Vice versa, the magnetic hardware developed may also allow for advanced light manipulation using enhanced magneto-optical effects. The material basis is predominantly provided by III-V or II-VI semiconductor quantum structures also combined with metals to form hybrid systems, hosting either localized or motile spins with robust properties that allow for versatile manipulation involving laser light and microwave radiation or utilizing novel tools such as ultrafast acoustics. The interactions between the spins will be tailored, either to suppress detrimental environmental interactions and maintain spin coherence or to corroborate interactions between spins. Thus, superposition and entanglement of quantum states could be established in order to achieve functionalities that cannot be realized in the incoherent regime. In that way, the ICRC could contribute to the future development of spin-optoelectronics for information technologies in the classical and the quantum regime.
