摘要: The fast dephasing of electron spins in an ensemble quantum dots is detrimental for applications information processing. We show here that can be overcome by using a periodic train light pulses to synchronize the phases precessing spins, and we demonstrate this effect singly charged (In,Ga)As/GaAs dots. This mode locking leads constructive interference contributions Faraday rotation presents potential based on robust coherence within
