Entangled states of matter are a crucial resource for many quantum tasks, but producing such states deterministically between noninteracting parties is quite challenging, especially in solid-state systems. Here researchers offer a protocol to entangle two ensembles of nuclear spins that surround two quantum dots connected by an electron waveguide, employing sequential interaction of the nuclei with spin-polarized electrons. The authors numerically demonstrate the efficacy of the protocol, even in disordered and noisy setups, which suggests its feasibility with state-of-the-art techniques in quantum information processing.
