摘要

半导体量子点是一种具有鲁棒性和可扩展性的量子信息处理系统。如果涉及的量子态相隔至少几十meV，则可以设想用飞秒光脉冲实现相干量子操作的超快序列。因此，具有高约束势的小量子点是有利的。由于其库仑相关能大，CdSe量子点是理想的候选者。

Femtosecond few-fermion dynamics and deterministic single photon gain in a semiconductor quantum dot

Semiconductor quantum dots are promising systems for robust and scalable quantum information processing. Ultrafast sequences of coherent quantum operations may be envisioned with femtosecond light pulses, if the involved quantum states are separated by at least tens of meV. Therefore, small quantum dots with high confinement potentials are favourable. Due to their large Coulomb correlation energies, CdSe quantum dots are ideal candidates.
