Physicist solved the puzzle of long ranged interactions between spins in In(Ga)As quantum dots
that there is an interaction between the spins despite the large distance between the quantum dots [1]. "It is indispensable to understand this interaction in order to think about possible applications [...] very good agreement between the experimental and theoretical results," Frederik Vonhoff summarizes.
