Popis: The application of spin based qubits requests understanding and control of spin relaxation time T 1 which remains challenging. Here the authors experimentally demonstrate the spin relaxation mechanism via hyper fine interaction and long spin-relaxation time T 1 ~ 57 s for a single electron spin in GaAs quantum dot.
